• Satellite A100 BIOS update - BAD CHECKSUM

  I've just updated my BIOS to version 6.0 that TOSHIBA said > 26/11/07 "this Bios update adds functionality to your system: Satellite A100 Toshiba 6, 00 - WIN (PSAAN).»

  My original BIOS was 5.9
  My computer works fine A100-33 but when my computer restarts, showed it to the BLACK screen.

  I noticed that it displays BAD CHECKSUM and suugested I select default BIOS but I * ignored this advice * that wanted this new Version of the BIOS.

  What means BAD CHECKSUM and what effects will have on my computer peformance please if any?

  Under the system information that is displayed for my BIOS Version/Date Phoenix Technologies LTD 6.00, 07/12/2007

  Name of the Microsoft OS? ® Windows Vista Home Basic

  Hello

  Don t worry if the message "bad checksum" will appear only once.

  'Bad checksum' means that the BIOS has been changed, rewritten or settings have been restored by default. Thus, whenever you save your bios settings, bios made a "checksum" to check the next time you start the settings were stored and all goes well. If something is wrong or has been changed, then the checksum stored since the last save a Don t match real new generated checksum.

  So if you make an update of the bios, all your settings will be modified logic - you get an error "Bad Checksum".

  Another reason for such "Bad Checksum" is an empty BIOS stack or a malfunction, so BIOS cannot keep it s settings and you will get every time you start the computer a message "Bad Checksum".

• Satellite 5105-S501 - Bad checksum (rom)

  Hi I have a Satellite 5105-S501.

  When I start it say bad checksum (rom), press F1 to the default settings.

  After I press F1 it says I have to insert systemdisc and press a key.

  What is a systemdisc?

  Can someone please help me solve this problem or I have to hand it get fixed?

  Sincerely

  Peter Hammarstrm

  "Checksum error/omission" may appear for different reasons.

  A question:
  You access the BIOS after pressing F1?

  Generally, this error appears if the CMOS battery is empty. In this case, you must connect to the AC adapter to the laptop and should leave it for about 20 to 48 hours connected to AC power.
  Then try again to access the BIOS and set the defaults.

• Satellite A60-202 after bad BIOS updated the PC does not work

  Hello

  After a very bad my BIOS update, my PC doesn't work and doesn't turn on.
  What to do now?
  It is Toshiba Satellite A60-202 with 512 MB of memory and 40 GB of HD.
  model PSA60E-OLP06TFR SA60-202

  Thank you

  HI Yves,

  Unfortunately, if the BIOS update procedure does not work (or fill), then it is likely that the BIOS in the CMOS chip had been corrupt and without it, you will not be able to boot your laptop to fix the problem.

  It will be necessary to bring (or send) your laptop to a repairer authorized to have reflashed BIOS.

  Kind regards

• Error message "bad checksum" satellite pro 6100 when starting

  Recently I tried to turn my laptop on when I got the message "bad Checksum"(je pense qu'il dit que) 'check the system press [f1] to continue. "" After I pressed f1 he came an options screen I did nothing for her and just keep then it loaded and stopped again. also I have to lie down on the back just for the first green LED lights up and when I have the battery in the charger does not charge the battery and even when it starts to load and I try to put it on the same orange LED sequence appear.
  so does mean the checksum bad message?
  Thank you

  Hi jam

  Price, we can only speculate because I heard that it is not the same for each service. Unfortunately, we have a? free help? and all licensed services can offer own prices. Contact the nearest service and ask how much will cost the cheque or the exchange of the CMOS battery.

  Bye and good luck!

• Satellite 1410-604-BIOS update > update BIOS Incorrect in the web?

  Hi there again!

  Now with a new and strange issue.

  We all know that tell old... "If it does not break, don't fix it." And if you put in more computer terms, "especially if it's a BIOS.

  Yes, we all know that the BIOS is something quite dellitate to manage. For some reason, we normally feel as if we manage something like nitroglycerine, or radioactive products. And it's because we all know who is put at risk at the moment: our (or sometimes other) computer, the whole system could end up as dead as some pieces of metal, plastic and son.

  Well. I passed through all of this, more than 10 times in my life, and only once, it went wrong. But since this old motherboard was already dead, it was not important. But I've always been EXTREMELY care. Allways cross checked everything before you do anything, allways has a backup and a way to allways and restore that backup... I did COMPAQ systems, which have been prepared in this way. A BIOS update was about about a disc, turn on the PC with the disk in the floppy drive and wait. And if you don't like the results, you just click on 'back to a previus BIOS' and that was it... very nice. And easy.

  A few days ago a friend gave me a Toshiba Satellite 1410 604 to solve some problems that have been her crazy. After you remove a Norton Internet Security has expired, install avast and scan, I found more than a hundred of files infected with a variety of viruses, malware, trojans, and everything you could imagine. Avast all removed, but the rest of the operating system was so unstable that we decide to format it and install from scratch.

  I asked for the restore disks, which obviously it failed because they were lost in one of his trips. After that we had confirmation of Toshiba representatives there is no disk recovery available for this model, because it is too old, we decided to install from scratch like any other normal PC and resigned to losing some of the utilities accompanying that CD and are not available for download on the Web site.

  I downloaded all the software available for this model, including two updates to the BIOS. (In reality an update, but in two versions: Windows and traditional) and prepared a CD with all the drivers and programs as if it were a new system installation. And everything was fine, no problems at all. Until we arrived at the wireless LAN card, but that's another problem is already solved (the mini PCI card for the WLAN does not support the encriptación WEP or WAP, and it is not possible to connect to any LAN encripted wireless).

  At this point, and when I started setting up and activation of peripheral PCMCIA and USB devices (this computer only supports USB 1.1, 2.0 not) I discovered this text from Toshiba Web site:

  "This Bios update adds functionality to your system.
  (BIOS stands for Basic Input and Output System. This program is stored in a chip memory dead on the motherboard.
  When the computer comes on, the BIOS is launched to perform various functions to start.)

  For more detailed updated information, please refer to Information update BIOS Toshiba"

  Quite specific. Isn't?)

  According to the information in this Web site, the available BIOS fits the following models:

  "Satellite 2410 414, Satellite 1410, Satellite 1410 - 654S, Satellite 1410 814, Satellite 2410-303, Satellite 2410-304 s, Satellite 1410 354, 2410-601 Satellite, Satellite 1410-401, {color: #ff0000} * Satellite 1410 604 * {color}, Satellite 2410-404, Satellite 1410-301, Satellite 1410-304, Satellite 2410 S403, Satellite Pro 2100, Satellite 1410 S203, Satellite 2410-304, Satellite 1410 554, Satellite 1410 S102, Satellite 1410 - 354F, Satellite 2410 703, Satellite 1410-303, Satellite 2410 - S203, Satellite 1410-801, Satellite 2410 603, Satellite 1410-902. ', Satellite 1410-313, Satellite 1410-802, Satellite 1410 714, Satellite 2410-354, Satellite 2410 514, Satellite 1410-614, Satellite 1410 704, Satellite 2410 515, Satellite 2410-504, 2410-702 Satellite, Satellite 1410 S103.

  Yes... it's here!

  Now when you go into the "Toshiba BIOS update information", you get:

  "Ref. FAQ: TRO0000000b07.

  A BIOS update is a {color: #ff0000} * operation is relatively simple and can be done by computer more competent users * {color}. All BIOS updates can be obtained from "BIOS update" Section download click here...

  Note: the BIOS files are specific machine the correct BIOS for your machine should be used. »

  Please note that Toshiba does not disencourage BIOS manipulation, on the contrary: they even encourage people to do. It is not badly needed, but at the same time that they encourage people to 'play' with such a delicate question, at the end of this page, in small letters, they say:

  "Toshiba provides this information"as is"{color: #ff0000} * without warranty of any kind * {color}, explicit or implied, including, but not limited to, the implied warranties of quality market or adequacy has a specific use." Toshiba shall not be liable to the topicality, accuracy, completeness or quality of the information provided. {color: #ff0000} * Toshiba is not responsible for damage caused by the use of any information provided, including incomplete or incorrect information * {color}. »

  This should trigger yellow alarms in our minds.

  + "Human error is inherent in man, and it is not possible to eradicate. It will be displayed always, sooner or later"(Prof. James Reason). +

  And finally, I made the mistake. Although I have read this warning, I remembered all these successful BIOS update with COMPAQ and relied for Toshiba. This update was available there, and Toshiba told me that it was for this computer. Great!

  So finally, I disconnected all devices (USB), removed the PCMCIA (WLAN), plugged the battery charger to avoid any possible battery problem, restarted windows, and then Windows started the update (windows version, such as recommended by Toshiba). This drug looked very nice, nothing different from what I usually see on these old COMPAQs.

  As reported by the update program, the system would restart. And in fact he did.

  Windows normally closed (a little faster than normal, but without mistakes, and since there is no other programs that most - even the antivirus not working - no), the computer turned off, all lights (normal) offshore, and then again on...

  {color: #0000ff} * BEEEEEEEEEEEEP... BEEEP... ... BEEEEP * {color}

  OMG! I never movement something SO bad. 3-1-1!

  And now... What a 3-1-1 is here? Award BIOS would mean no card graphics or video deffective card, but it is not true, because it worked 20 seconds ago. There are BIOS.

  He never came again to life. He's still 3-1-1 beep.

  But now comes the investigation on the human factors involved in this accident.

  I found I committed the following errors:

  * (1) * rely in the constructor, even if they have WRITTEN their information may be incorrect or incomplete. (BAD if I was a detective QA & QC).

  * (2) * I cross checked deep enough (until it was already too late).

  * (3) * I haven't looked above for how to make a backup of the BIOS to restore must anything deceive you.

  * (4) * let Toshiba lead me to a path that I didn't walk, just because of their supply of 'increased functionality.

  * (5) * Beleave in Toshiba when they said "relatively simple operation and can be performed by the most competent computer users"... they never said it is infallible. "."

  Then I began the most interesting part of the investigation.

  {color: #0000ff} * "what went wrong?" * {color}

  Obviously, the update of the BIOS has not somewhere, somewhere. And I wanted to know what and where.

  First thing, I discovered that there is another Toshiba search engine called "askiris" ([http://askiris.toshiba.com]) and I looked to see if, for any chance I could get the old BIOS 1.20 version which was installed at the origin of this machine.

  And I found something... VERY interesting:

  GOOD! Or not?

  Let's take a look:

  First thing I did was download all four files.

  Then I took the same version that made the accident: 1.40

  I unzipped the file, which I found:

  And I got my first surprise here: there is a {color: #ff0000} * README. TXT * {color} that was not present in the file that I downloaded earlier from the repository of drivers.

  So I went the readme.txt and I found this:

  'README. CDC TXT 31/01/2003

  Satellite 2410-S204.

  Please note that the model 1410-604 is * NOT * listed.

  I thought ' well, there must be another archive... ". »

  But then I realized a name that seems familiar, that is, in the directory where I unzipped this file 1.40, and the name is:

  {color: #0000ff} * 2410A9V140. EXE * {color}

  So I took the other file, the update of BIOS_Win, and I discovered that the name of the file is:

  * {color: #0000ff} 2410A9V140. EXE, {color} * (Ups!)

  So I once again, uncompressed to find:

  * {color: #ff0000} they have two 20 files and 1 046 461 bytes. I asumed that they are the SAME two folder {color} *.

  And the readme file does not list the model 1410-604 in its readme file, so I can't explain it except as a Toshiba error. * {color: #ff0000} they put an incorrect BIOS on their website and has proposed updating and somehow lead to such mistakes. {color} *.

  (Except in the case that one of these models is a name that is different from the model 1410-604, and if that's the case... now I don't know why this BIOS do not work with this computer).

  The worst thing is that neither the other files (V1.10, 1.20 and 1.30) lists the 1410-604, apparently so no solution possible workaround for this problem. I need an original v1.20 to the CMOS, and Toshiba seems to have. They offered me to solve the problem, leaving the laptop to an ASP, and pay only € 95 for the work and about € 280 for a motherboard replacement, I will get it resolved. But they offer no guarantees of their possibilities because is a model "too old" and "abandoned" and "unsupported"...

  In other words, they said 'you don't have to bother with it, just go and buy a new' (something of quite out of my reach in this time of crisis): P

  Thanks for reading so far.

  Now, what I need is to get ideas on a work around for this, my ideas are:

  (1) the CMOS has some startup that works (it allows a roll-back if you have the appropriate file). So I need a good BIOS to burn in the CMOS memory, the SAME SAME model (a backup BIOS) but the backup should be sufficient for the burning program (CHGBIOSA.COM).

  (2) it is always possible that the BIOS might be OK, but the CMOS data has been corrupted somehow. If so, the CMOS of compensation could solve problem. But I wasn't able to find a clear cmos from the outside button, and after disasembling I took battery, with no good result. I try to leave the MOBO without battery for a period more long (I left it about 20 seconds) just in case where 20 seconds are not all capacitors for well pass zero values. I don't have a lot of hope in this point.

  (3) try to get a REAL good update from Toshiba. I contacted technical support several times, and I was able to verify that they are only - phone operators, with a script in front of them, and when the problem is going - out of reach, they fall in the same response: "you must go to an ASP. I still have a faint hope to find someone who really knows a little and could illuminate with a good BIOS in this disc.

  (4) as far as I could find, this BIOS is not any BIOS-manufacturer known. It seems that it has been developed by Toshiba (own brand), so the Phoenix crisis recovery disk won't be of any help here. As well as any other BIOS recovery tool not designed for Toshiba BIOS. But I'm open to all ideas, which could be put to the test more or less safely. (Remember that the 'BIOS-BOOT-PART' feature still works, I don't want to lose that possibility alone of redemption).

  Wwwaaaaoooowww... what a falks long post! Sorry about that!

  Forgive me, but I wanted to be really clear.

  Someone give some tips or advice will be greatly appreciated.

  Please don't say that I shouldn't be doing... I already know that. I already did some research and found my mistakes, not to repeat them. Now, I need to spend, to move and to try to solve this problem, or at least learn to solve similar things. As much as possible.

  Thank you once again, in advance, and sorry again.

  Modified subject to beter reflect what the problem is (apparently erroneous file BIOS in Toshiba Download Center).

  Hi Fenix,

  Wow... He tooked a lot of time to read your post...

  Maybe I can help you.

  The Bios in the website is the right one. If you have downloaded the right version of the Bios.

  Toshiba America, which has most of the time the Askiris you used isn't accurate models for Toshiba Europe.
  This should be the reason, why does not the readme file contain the European model.

  I'll try to do an update of the fresh Bios using the update of the traditional Bios.

  Copy the files on the disk, put it in the floppy drive, press and hold power on the notebook tab.
  After that the laptop is off, press on and hold the key on the left side of space power on the laptop new bar and wait until it turns off again.

  If your laptop does not power perhaps the most, the RAM is default?

  Therefore, if the use of the traditional Bios or change memory doesn't help, and your laptop is still dead you should go to a SPA, but it will cost money.

  I now have my fourth Toshiba laptop and I had never problems with the Bios updates.

  The 1410 is very old I think, so before you go to a SPA, I'd buy a new ;)

• BIOS rom checksum error

  I have a bios rom checksum error on my hp pavilion a6530f. I replaced the battery on the motherboard and reset the CMOS but it still shows the black screen of death with the messages.

  BIOS ROM checksum error

  IDE ATAPI device detection...

  Found CDROM, try to start her... In case of failure

  Detecting A floppy drive media...

  Insert system disk and press enter

  and beep every few seconds.

  I do not have a system disk and when I try to press F10 or F1 to access the window with the version of the bios information, according to the instructions I found on the HP site, nothing happens. I can't also find a download for any bios drivers for my pc on the Web site.

  Before this past that I have had some freezing problems and a lot of questions of adware.

  I used to operate and maintain fuji printing and developing of films but I'm kinda a tyro when it comes to PCs.

  Is that mean that the motherboard is fried? Or if not, where can I get the download that I need to solve this problem?

  Hello again cienerose,

  If you type the F10 at startup and nothing is happening on your computer (you don't get in your BIOS) then the problem you describe seems to be a physical problem, and I think it would be better if you contact HP Support for service options.
  
  I want to thank you for display on the HP Forums. Have a great day!

• Desktop M8000 giving Bios Rom Checksum Error

  Hello

  My brother-in-law gave me their old tower to see if I could not going again for their children to use, the decent machine actually, he had 2 internal hard drives in it and he said it was more than ever and lock up often.

  The pc don't was not start (sitting at an empty screen) even if it had worked before, so the first thing I did was to remove the two hard drives and their hung outside for my main pc, he said, I wanted to see if they were healthy and if they had the virus on them, etc.

  Health check, past, defragmented both drives them (OMG they were horrible) and on the storage disk ran a virus scan and spyware scan (zero problems) spybot seek and destroy and completely updated avast updated etc.

  On the main C drive, I did Defrag, ran the spybot captured about 10 things mostly of cookies, nothing horrible, then ran avast, it is 17 things in temporary files, remove hit at the end of the scan, re ran the scans and it came out clean.

  Then the two drives are checked as work/healthy, defragmented, virus and spyware cleaning, put it back in the system and I still get the screen white, but maybe 1 out of 10 times I get

  Found the CDrom, boot from it...

  But no matter what I (F-keys, deletion etc.) I can't get the pc to answer or do anything.

  I also removed and then re-inserted the cmos battery thought he could do something to help her back running but no luck, I have a new battery to install to try it but thought to take a few minutes of waiting and re - install could lead to something.

  PG said 350 ms

  These values of 12 volts out worrying par.2 1 tension or limits?

  The unit announces it will sound in case of errors, I get no flow in the readings or beeps, I just wanted to confirm on this.

  Cuz at this point, I checked the ram, hd, battery changed, makes the integrated reset cmos jumper option, but I don't always get anywhere then I suppose that its cpu or motherboard at this stage.

  Hello FTLOSM, reads that you list are fairly normal. A difference of one or two points on the readings should not be a problem, especially if the power supply is connected and powered. The 12 volt rails are mainly used for engines on the disks, so a small difference in the actual 12 volts would be well within tolerances. If 3.3 volts reading falls below 3 volts, then I'd be concerned.

  I would tend to think that the motherboard is the culprit, since it is rare that a processor will fail under normal circumstances.

  It usually takes a voltage spike to get a processor.

• 'bad checksum' error when starting

  When I rebooted my computer, today, the ordinary boot process was interrupted by a black screen with an error message that says "bad checksum" and gave me the option to start anyway, or enter the configuration.  I chose to start instead of enter the configuration.

  After I submitted this question on the forum, I restarted my computer and got this error message (I typed exactly how it appeared on my screen)

  change of service configuration
  : Disk error
  Press F2 to continue, F1 to enter setup

  .. then I pressed F2 to continue and then the message 'boot sequence error' appeared for about 0.5 sec under the previous error message above, then my computer started as if nothing had happened

  I want to know what caused this 'bad checksum' error and the sequence/boot drive error and how to solve the problem (s)

  I have 32 bit Windows Vista Home Basic w / service pack 2

  Thank you

  Thank you for visiting the Microsoft Answers community forum.

  Has anything changed summer on your system recently as new hardware or software installed any new updates?

  What kind of computer you have - laptop or desktop computer and what brand and model?
  This information will help us to help you solve this problem.

  Start by checking the file system corrupted system and check the hard disk for errors.

  To run the System File Checker tool, follow these steps:
  Click Start and type cmd in the box start the search.
  Right click on cmd in the list programs, and then click Run as administrator.
  If you are prompted for an administrator password or a confirmation, type your password or click on continue
  At the command prompt, type the following line and press ENTER:
  sfc/scannow
  When the analysis is complete, test to see if the problem you are experiencing is resolved.

  You can help solve some computer problems and improve the performance of your computer by making sure that your hard disk has no errors.
   
  1. open the computer by clicking the Start button, click computer.
   
  2. right click on the hard drive you want to check, and then click Properties.
   
  3. click on the Tools tab and then, under check for errors, click check now.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  To automatically repair problems with files and folders that the scan detects, select automatically fix file system errors. Otherwise, the disk check will simply report a problem, but not to fix them.

  To perform a full disk check, select search and attempt to recover bad sectors. This scan is trying to find and repair physical errors on the hard drive itself, and it may take much longer to complete.

  To check for errors file and the physical errors, select both automatically fix errors in file system and search for and attempt recovery of bad sectors.
   
  4. click on start.
   
  Depending on the size of your hard disk, this may take several minutes. For best results, do not use your computer for any other tasks while it checks errors.

  Note: If you select automatically errors in file system of fix for a disc that is used (for example, the partition that contains Windows), you will need to reschedule the disk check for the next time you restart your computer.

  Send us information about your system and the results of these tests.
  Thank you

• BIOS rom checksum error does not start

  Compaq

  will not boot at all

  When I turn it on it automatically goes to a black screen that says:

  Award Bios BootBlock v1.0

  Copyright (c) 2000, price Software Inc.

  BIOS Rom checksum error

  keyboard err or no keyboard present

  IDE ATAPI device detection...

  Found CDROM tries to boot from the pass it...

  can anyone tell if this can be fixed if it can and you know I would appreciate it a lot

  Oh and I got a windows vista disc to see if it downloads it, but just on the same screen

  The "boot block" needs to load the rest of the BIOS of a memory chip. Since it doesn't, either the battery on the motherboard (a piece the size of a $0.25 coin silver) has failed, either the content of the memory chip cannot be read.

  Replacing the battery is fairly easy.
  First of all, notice the writing on the top of the battery.
  You will need to put the new battery into the socket,
  with similar writing facing face up into the socket.
  Look on the edge of this battery to a small 'finger' which holds the battery in its socket. Push this "finger" of the Center, and the battery must be able to be raised.
  Remove the accumulator at any computer store and get a replacement.
  Insert it, and then try again.

  If the problem persists, then either he must:
  * Replace the motherboard
  * replace this chip memory (which can be soldered on the motherboard at all times).
  * replace the computer, taking the disc drive of the old computer and its connection as a 'slave' the drive in the new computer.
  * take your computer to an expert technician.

  The attempt to boot from the CDROM is a process "emergency", to use when you have a specially created CD disc that contains a copy of the software to load into the memory of the BIOS chip. It is not a 'normal' start (to load the Vista disc).

• Aurora R4 BIOS ROM Checksum failure but boots 50% of the time?

  About half the time to try to start it normally does so and the other half it does not, start but all the lights and fans turn but nothing appears on my monitor and it gives 1 beep every seconds for BIOS ROM checksum failure (Possible MB). It started after the installation of Windows 10.

  Any help? and why would it only to start half the time?

  I solved the problem!

  Thanks to Tesla1856 and this post with links to Tesla by Cass-Ole messages. I flashed the bios A11 of A08 by creating a USB bootable and update of the dos environment. She completed successfully and now I can now boot Windows every time and have either messages with beeps.

  So far, it seems that the Windows activation message has been linked to this issue, and the issue of 'previous overclocking failed ".

  The only thing I can think that caused it was installing Windows 10 he apparently stores the key "deeper" in the motherboards bios, but I don't know

  If anything, I would just restore my old BIOS, if possible.

  Please, someone help!

  Hello

  Have you tried to access the BIOS and tried to set it to default settings?
  Isn't it? Do this!

  By pressing the F2 key, you would be able to access the BIOS. Set the BIOS back to default settings and set up.
  Then start the laptop again and check if the same notification will appear on the screen.

• Satellite C660-1TT - BIOS problems

  Hi all...

  I sat and would update the bios for my Toshiba Satellite C660-1TT (PSC1QE-01D006N5)

  Sloopy as I was, I left the computer to get a coffee, * obviously one of my children was there * and press a few buttons. This resulted in the computer 'frozen' after a while I was forced to turn off.

  Now change back the time and date each time I start the computer, and I can´t get the wifi to work.
  I tried to reinstall the bios again but then get the message that I already have the same or more recent bios and installation is complete.

  Someone who can tell if I wrong somehow the computer into thinking it is a newer version or the mabye bring in the former and then update?

  Grateful for any help! Robert

  (excuse my bad English)

  Hello

  To my knowledge it is not possible to downgrade the BIOS in windows mode, because you will always have a notification, this new version is already installed.
  To my knowledge the ASP technician Toshiba may downgrade the BIOS but only using the traditional version of BIOS (BACK).

  But I recommend to test this workaround solution.
  Shut down the laptop. Remove the battery and unplug the AC adapter.
  Now let the laptop disconnected for a longer period of time, I think about 3-4 hours
  Then plug the battery adapter and ac and access the BIOS by pressing F2 to turn on/off the unit.
  Here, you must set the default BIOS (F9) and save the changes.
  Now, start Notepad and check how it would work.

  Usually, the date and time resets because the CMOS battery is empty. But I can't imagine that this could be a problem here, however, you can reload the CMOS battery running the laptop on area for 18 to 20 hours. During this time the laptop must be ONE.
