• EFI and SMC firmware MBP 8.1 do not match list Apple

  Hi all

  I have a MacBook Pro 13 ", beginning 2011, 8.1.

  I changed the hard drive with a Samsung SSD 850 EVO and installed the OSX El Capitan 10.11.4 Version (15E65) with a clean install (format, then install).

  After that, I noticed that my fans are working more than usual. So I checked the SMC and EFI.

  When I check the presentation of the material, here's what I find:

  Model identifier: MacBookPro8, 1

  Boot ROM version: MBP81.0047.B2C

  Version of the SCM (System): 1.68f99

  But it seems my SMC and EFI firmware do not match Apple list/recommendation:

  MacBook Pro (13 inch, early 2011) MacBookPro8, 1 MBP81.0047.B2A (2015-001) 1.69f4 (SMC 1.7)

  I found this information here:

  On the updates of the EFI and SMC firmware for Mac computers with processor Intel - Apple Support

  I am trying to update, but I received the following message: "this software is not supported on your system."

  Someone at - it already had the same issue on the fans or mismatch SMC/EFI?

  Kind regards

  Hi the-Mat:

  I have the same exact computer and the exact same hard drive. Here are a few impressions of screen.

  

  My information is the same as yours.

  

  

  The version that you and I have is a more recent version. We have MBP81.0047.B2C instead of B2A.

• HP Envy m6 1125dx: how to upgrade the bios and uefi without a hard drive

  I can't install OS, including Windows 8.1 discs. After that I get so far along, installing Windows says there is no hard drive, but it's there!

  I see that my BIOS is outdated. When I download the new BIOS from hp.com, I get an executable file

  which of course does not work on a computer that does not start. I can't find the bios file when I run

  the executable file on another laptop.

  So, I want to update bios and uefi to see if that helps with my problem.

  The current Bios is F.11

  Quite true.

  See the image below.

  What is necessary to do is to extract the sp66782.exe file to a folder on the second computer.

  Rename A 018, 4. FD file to 018 has 4. BIN and save it to the root of the USB stick.

  Plug the key into a port on the computer laptop problem.

  Press the power button / stop the laptop and immediately press and hold the Windows key and the B key until the phone reacts and starts the BIOS recovery.

  If all goes well, that will recover the BIOS corrupted with the new copy which is on the flash drive.

  There is a detailed description of another method to do this on the thread of the forum according to 3rd party.

  Using this method will result in certain risks that you have to accept if you decide to follow this way to unbrick your laptop. Any update of the BIOS manually is risky.

  

• I have problems to install the UEFI BIOS and UEFi diagnostic on my HP probook 4530 s

  I recently bought the probook 4530 s, but for some reason, my hard drive has begun to view the status of the dynamics. I reinstalled the window and the status of the disk was returned to base. However, now I have a problem in installing UEFI BIOS and UEFI diagnostics. whenever I try to install it, a message that you do not have HP_Tool partition would like to install it? I hit the Yes button, but as I already have 4 discs on my new system fail to form. Thus, the operation failed.  so can you help me solve this problem?

• Re: Satellite C850 and UEFI BIOS settings

  I have laptop Satellite C850 - 1 2 with Windows 8.1

  When I boot, it shows a toshiba logo, not the original flag 8 Windows. It is not so much a problem, but I can't change because the parameter is blocked within the parameters of the UEFI. How can I change this?

  I already tried to change through the windows in different ways, but each time it will change the UEFI!

  Help?

  To be honest I don't know what to do, you mean with blocked settings, but it can be changed in the BIOS settings.
  What you need is to make complete OS stop http://aps2.toshiba-tro.de/kb0/TSB2B03EY0002R01.htm and after having done that, you can restart the laptop and enter the BIOS (try F12) settings and then you can change all the settings of the BIOS.

• Pavilion H8-1205eo: Problem with 980 Ti and UEFI

  Hello! A few years ago I upgraded from the Radeon 7570 standard to use a 670 gtx graphics card in my H8-1205eo and everything went well. Recently I bought gtx 980 Ti to run the latest games at high heat. When I started the pc after installing the card, that it would not go beyond the blue HP screen and pressing ESC to enter the BIOS would show only a black screen with my characteristics listed. After reading a little online, I came to the conclusion that I need to change legacy to UEFI. I looked around a bit in the configuration menu, but wasn't able to find a way to change this in the UEFI. Should I buy a new motherboard, or I simply do not found the setting?

  Peter, welcome to the forum.

  You can't find UEFI because the computer is equipped with a standard BIOS.  HP didn't start using UEFI until mid-October 2012.  There is no way to upgrade to UEFI.  The last series of video card that did not use UEFI was 640 gt.

• T400 and UEFI

  Hello world

  I recently saw a video (http://www.youtube.com/watch?v=DLwaKb6pLrc&feature=player_embedded), and it keeps me hopeful that someday my T400 must load a day the start time of 10 seconds.

  I was wondering if you think it will come to the T400 or would be Lenovo will not send UEFI on their new products only?

  UEFI is not available on the T400, she should never be released with the T400 machines.

• 2481 - 3SG L530 - first 1.4 GB of RAM of 4 GB 'reserved by material' and now 2.2 GB? Problem BIOS/UEFI?

  Hello

  Using a Thinkpad L530, which becomes a few weeks over a year (-> warranty expired). Running Windows 7 64-bit on it (in BIOS compatibility mode).

  There is, at the same time (cannot say for sure) four months when I installed an update of the BIOS (which jumped several versions), then all of a sudden my resource monitor showed 1.4 GB of memory reserved by the hardware.

  I did some looking and also called the hotline of Lenovo Germany support (because they don't send support) because my unit was still in warranty, at this time, but useful guys might not help me get back memory - the conclusion was that for some reason, that the update of the BIOS must have changed how the integrated graphics card memory is managed intel (size is dynamic). Due to the fact that a downgrade to BIOS was impossible (due to some changes), they also offered to replace the motherboard with an older BIOS revision, but I refused (I have that it will not much help because I need to upgrade the BIOS later anyway, and really, I didn't miss my primary work machine).

  However, yesterday, after having done nothing more to try the different operating system a few live CD and certainly not after installing a new BIOS update or similar, sudden reserved hardware memory was 2.2 GB (I can say 100% certainty that Monday, it was not, since I was unable to resume a VirtualBox VM suspended Monday due to the change of configuration of memory - and to make sure I also was installing drivers) (or updates to the BIOS since Monday).

  So I'm now sure that this problem (and probably also the other I had before) was not caused by an upgrade of the BIOS or changes how Intel's integrated graphics is managed, but more likely a BIOS/Firmware bug.

  Also, the missing memory shows not only in Windows 7, but when I start a live Linux CD or at memtest86 boot.

  So I studied a bit and found out, that if I boot a Linux live CD (which support it) in UEFI mode (with CSM disabled legacy support), suddenly I can reuse many of my 4 GB of RAM. But only here, and I would use it on Windows and not by the re-installation of a license of Windows 8 in UEFI mode...

  Some information that I have collected (such as memory card EFI and card memory at the start of Windows and Linux, and Linux UEFI, screenshots of Windows) is available in this post in another forum: http://superuser.com/questions/746497/what-hardware-device-used-to-eat-up-1-4gb-of-my-4gb-ram-and-no...

  Does anyone have any suggestions

  -How do I know where this memory is gone?

  -Why memory cards so different between boot UEFI and BIOS/CSM

  -How to get the memory (without replacement)

  I heard of many problems UEFI (not only for Lenovo but also other suppliers) is caused by certain invalid EFI variables, is there a way to reset all variables of the EFI on my laptop (I am aware that I may have to reconfigure the boot settings later)? I tried flashing the BIOS (a version at the bottom and back again) and installation by default, or reset settings Secure Boot loading, but that did not help for my problem.

  
  

• Can't get running dual boot Linux (Fedora) and Win8.1 in UEFI Duo 11 &amp; secure boot mode

  Hello people,

  last year, I bought a 11 (Intel i5, 1.8 MHz, 8 GB RAM, 128 GB SSD) Duo with Win8 (64-bit) installed in secure boot mode. December 2013 I updated the OS 8.1 with a new license and curled UEFI & secure mode active, a few days after I installed Fedora 20 64-bit.

  Installing linux running properly, but I don't get any what startup, or UEFI GRUB menu and only earn 8.1 starts automatically. I checked the EFI partition: all files are installed in the appropriate directories.

  Can someone help me get the dual boot running?

  Thanks in advance

  Michael Wachs

  Hello again,
  Mission accomplished, I have a dual boot win8/fedora20.

  Well, it was much more difficult than expected.

  First of all, thanks to this guy, it's a bit more clearly how noncompliant efi bios on vaio actually works:

  so, let's keep in mind that the start process seems to:
  Look in /EFI/Microsoft/Boot/bootmgfw.efi; If present, it starts.
  Search in all subdirectories of /EFI/ for grubx64.efi. If present, it starts.
  Start /EFI/Boot/bootx64.efi
  Displays an error such as "The OS not found" message.

  Now, that's how I managed to do so, please note that:

  • It's more a hack here-I-fixed-it rather than a clean solution, but it works
  • There is probably a more easy/better way to do
  • a step may be unnecessary (I will say that when I suspect, but I will definitely not return to test)
  • I'm Italian and my English is awkward

  (1) enter the bios settings, select the boot from cd/dvd and disable secure boot (this may be unnecessary and can be re-enabled at the end of the process, I don't really know at the moment)

  (2) use the Fedora dvd installation (NOT 'live' one since you will need the feature of 'rescue') (Finally, you can use a direct to start and then go up and chroot for installed partitions, but it is longer)

  (3) save the system installed, this should mean pressing enter three times and ending up in a shell

  (4) if all goes well, run:

  chroot /mnt/sysimage
  

  (5) go to/boot/efi/EFI and follow these steps

  mv Boot Boot.old
  mv fedora Boot
  cp Boot/grubx64.efi Boot/bootx64.efi
  mv Microsoft/Boot/fwbootmgr.efi Microsoft/Boot/bootmgfwFUBAR.efi
  

  Now, this way our graceful bios not compliant will not find Microsoft file and will head to Boot/boot64.efi (fedora one). Unfortunately, grub scripts does not detect windows, so we need to manually add Windows entry in grub conf.

  (6) take note of the UID of the EFI partition:

  grep /boot/efi /etc/fstab
  

  (Well Yes, there are safer ways)

  (7) edit /etc/grub.d/40_custom and add this:

  menuentry "Windows 8" {
  insmod part_gpt
  insmod fat
  insmod search_fs_uuid
  insmod chain
  search --fs-uuid --no-floppy --set=root A609-3B1E
  chainloader (${root})/efi/Microsoft/Boot/bootmgfwFUBAR.efi
  }
  

  (8) now we will (re) making our new config (in our new location):

  grub2-mkconfig -o /boot/efi/EFI/Boot/grub.cfg
  

  I fear that this step will be necessary whenever there is an update to the kernel

  9) restart with fingers crossed

  Oh, I currently have a working dual boot windows 8 / 20 on my vaio fedora.

  My biggest fear this time, it's some obscure windows update could restore the original Microsoft/Boot/fwbootmgr.efi. Finally, I could rename it again, still, it would be boring. We'll see.

  What a great way to spend a Saturday morning.

• New HP desktop, Windows8, Ubuntu, UEFI and a desktop computer that is no longer start

  I have a new HP desktop computer purchased just before Christmas, 2012.  Not realizing the problems with Windows8 and UEFI, I tried to load the version 12.1, Ubuntu, and now the Office does not start.

  Here is the chronology of the events:

  1A tried to install Ubuntu linux 12.1 with dual boot NO

  2 once installed Ubuntu, the system would not start and crashes with an error message

  3. accessed in UEFI menu and security disabled for all boot devices

  4 tried to start again, but the only thing on the screen is a picture of Seattle and the system will not meet any keyboard input

  At this point you can power cycle this machine, everything you want, and it puts just a photo of Seattle.  I can't access BIOS UEFI, or anything like that and the machine will not respond to any keyboard input.

  I did some research and it seems that this new version of the UEFI running on this desktop computer will not allow the machine to run anything other than Windows8?

  Any ideas on how to solve this problem?  I don't want doesn't matter what Microsoft anything running on this PC, and want to dual-boot.  I have not the recovery disc for this desktop computer.

  I think about how to solve this problem first becomes the machine to respond to keyboard entries, enter the UEFI and re - enable security this could allow me boot Windows8 still?

  Thank you!

  I finally got the machine to respond to the keyboard.  I found the solution on a linux Web site

  1. turn off the machine by pulling the power cord

  2. remove the battery

  3. press and hold the Power Off button for 60 seconds

  4 replace the battery

  5. start and hold down the ESC key

  BTW, I will update this thing with some notes as this can help someone else.

  The machine is a brand new HP P2-1310.  It comes with Windows 8.

  Try to wipe the hard drive and install linux has been in vain due to the new implementation of UEFI.  At best, I could install linux on a new partition, but the machine does never start the linux OS.  It will start only Windows8 successfully.

  As near as I can tell, UEFI will prevent any OS other than Windows8 currently running on this computer.  See linux UEFI as a kind of security attack and simply prevents the machine to use.  The Open Source community works now this last attempt of MS and PC manufacturers to prevent consumers who buy a new PC to install anything other than Windows8.  Run a search on this issue and you can get more information on the latest status.

  My guess is that sometime in 2013 different versions of linux Open Source will receive the digital signature required to interact with UEFI and load their OS on the new PC, or they will develop a workaround solution.  My suggestion for anyone considering buying a new PC that intends to install linux, immediately after that purchase should consider carefully what is not possible.  Right now I still can't do and I'm stuck now with Windows8.  If I had to do it again, I will not buy a new PC, but rather just go online and buy something.  After this experience I discovered used PCs with fast processors and a lot of memory can be purchased for $100 or less (craigs list), and because they are pre-UEFI, they will be easily load linux.

• EliteDesk 800 G1: EliteDesk 800 G1 does not boot UEFI disks immediately after-&gt; UEFI BIOS change

  I am changing our configuration of the BIOS boot in the UEFI. I tried to simplify the problem.

  I boot via PXE BIOS of SCCM task sequence and perform following actions:

  1. Apply UEFI Secure Boot configuration with BiosConfigUtility (enable Secure Boot, boot which is ignored anyway... order)
  2. Fixed disk partition type as TPG
  3. Create Fat32 partition to boot EFI and an NTFS volume for the data
  4. Apply WinPE to NTFS and copy the boot (bcdboot) in Fat32 files
  5. Set the volume to Fat32 as ESP
  6. Reset

  Now BIOS does not allow me to start this disc. Disk appears in 'Device Configuration', but not in the boot order.

  If I start again to PXE (now in mode UEFI) and check the contents of the disc, everything seems in order. If I reapply my script to repeat steps 4 and 5, and then the next time the disc will apper in the boot and boot order.

  If before the first attempt of UEFI, I put in a known UEFI boot disk, the system does not start it no more.

  I think that there is a bug in the BIOS.

  I saw something similar with Z620. When to apply some config past to the BIOS, the system is no longer shows startup valid drives in the boot order (this attempt was in BIOS mode). Emulation of the RAID controller is switched back to AHCI has worked around him then. But this time I'm not emulation of the controller.

  As BiosConfigUtility reports that it has fixed start changes but when reading them back (before or after the restart, they are the same). It's not as important, but

  BiosConfigUtility 4.0.15.1

  BIOS final v2.68

  My repro led nowhere (successful boot) but I was hired by HP support and all by responding to their email, I accidentally found the question.

  My BIOS setup script was a command to disable temporarily BitLocker if configuration is repeated his request for a system that is already deployed.

  manage-bde-protectors-disable c:

  However, this had inexplicably FAT32 partition become encrypted. If I started to UEFI PXE SCCM WinPE on the next boot, silently erased WinPE encryption and system would be on hard disk again, causing confusion.

  But when, for a test, I booted a Linux LiveCD, it showed encryption.

  I guess it's been like this for a while but only in this case C: was be the UEFI boot partition (usually it's system partition). In hindsight, my repro of WinPE image have also components BitLocker...

  I deleted command BitLocker and now it starts normally on hard drive after the configuration change. Detective Conan for time to engage the support of Microsoft and HP...

• HP Envy Rove: Boot with MBR instead of EFI without removing the GPT partitions

  Hello

  I mean, how do I start using the MBR without destroying GPT partitions or files EFI?

  I don't have an option in the BIOS to select the 'priority '.

  I have the BIOS with the e.17 Rev.A (latest) firmware

  @afeno

  Welcome to the HP Forums, it's a great place to get help, find answers and advice,
  Thanks for posting your request, I'll be more than happy to help you

  If I understand correctly you want to use the trunk legacy rather than the UEFI boot, before getting into the details, however,

  Here is the difference between Boot EFI and start-up of the legacy
  
  This is the process used by the firmware to find the target of starting:
  
  Legacy boot is used by the firmware BIOS boot process.
  The firmware keeps a list of installed storage devices can be bootable (Floppy Disk Drives, hard drives, optical drives, tape drives, etc.) and list them in a configurable priority. the POST procedure has finished, the firmware loads the first sector of each target of memory storage and it scans for a valid Master Boot Record (MBR). If a valid MBR is found, the firmware passes execution of code found in the MBR, bootloader that allows the user to select a partition to boot from. If we don't get, it proceeds to the following equipment in the boot order. If no MBR is found at all, the user is presented with the famous "Please insert system disk".
  
  UEFI boot is used by the UEFI firmware boot process.
  Firmware maintains a list of volumes of valid boot called EFI Service of Partitions. During the POST firmware procedure UEFI scans all bootable storage devices that are connected to the system for a valid GPT GUID Partition Table (). Unlike a MBR, a GPT does not contain a boot loader. The firmware itself scanning the closure for a score of Service EFI to boot from. If no boot EFI partition is found, the firmware can fall back on the boot of the legacy method. If boot UEFI and legacy boot fail, the famous "Insert system disk" will be presented.
  
  In general, the UEFI boot is more desirable.

  And if you want to know how to convert a GPT to MBR or convert MBR to GPT disk: click here (3rd party link - please ignore the ads).

• Satellite M50D - A - 10 L - installation of Windows 7 UEFI

  I m trying to install Windows 7 on TOSHIBA Satellite M50D - A - 10 L with UEFI boot.

  First time I used facility with CSM Boot EFI and it worked fine.

  But after I tried to spend in UEFI and make the installation of UEFI, whenever it starts loading setup files and after freez windows on "Starting Windows" screen.

  I have two pieces of these ultrabooks and they do the same thing.

  I used Flash disk, USB CD-ROM, two different versions of windows 7, but it have same endpoint...

  Secure boot is disabled

  I've got a Satellite M50 - A model (its similar to the M50D-A, but it was equipped with instead of ATI GPU nVidia GPU) and able to install the Windows 7 change the start mode MSC mode.

  Generally the UEFI boot mode can only be used for the system support UEFI as Win 8 or 8.1 win and some Linux distributions.
  Win 7 isn't taking system support UEFI.

  However, there are various workarounds to install Win 7 64 bit (not 32-bit) in the UEFI using the partitionstable GUID (GPT). Win 7 64 bit only contains the UEFI boot loader.

  But, very important is that UEFI installation isn t available (by default) is booting from USB due to lack of uefi boot loader! In case you use the key of USB for installation, you must add the UEFI (search in google for details) Start menu.

  Finally and above all depends on BIOS support in the case where the BIOS would only mode Setup CSM; all of these solutions workaround would be unnecessary.
