That means the AHCI Mode, Mode RAID & SATA IDE Mode in the BIOS settings means

My computer is having problems when I bought all first it was from another provider which came as a set overclocked PC up the unit everything needed had to be put in my case & add existing hard drives & DVD etc. readers added on the implementation. I used the same location for more than 10 years before that I always built them myself I can build a good setup computer I correspond to different parts inside each other, and then he tested & sent.
Unfortunately, the store has closed & the owner is sick cannot get their hands on him more & I had to get some add on things like new SSDS & some other bits in my system & the young boy said he would could do this job, but everything went wrong & I lost all new so I decided to recycle me like I used to do it before windows 7-64 came out I was going through a rough patch with me being paraplegic in any case it is difficult to build a new PC, so I chose this store & their confidence that went wrong now & I've been research & learn to catch up with the new technology, I do what I do anyway.
Thing is my system is never one that you can purchase a manufacturer & I left it with the young boy & it came out all memory & was not necessary but of course upset of that ruined the setting completely overclocked so I did it myself & I got the work faster than ever, & quieter PC I just got the score that he had now , so I'm happy with it, but the names I came across while overclocking I came across that I'm not average or really lot as were dealing with Fast CrossfireX DDR RAM 1600 MHz.
Please don't tell me that I should not be messing around with what I made since 1989 & made great strides in how everything works, I am not aware about this sort of thing I know SATA what it is & done, but those responsible for setting came from the part of overclocking in the BIOS I put then correctly , but I wanted to know what they represent in more depth. Thanks to anyone who can put me wise on these 3 points only. Malcolm.

I'm pretty sure that you are on the wrong "forum" for this type of topic. This forum is designed as a support Pro-type Surface ultrabook/tablets and tablet-like Surface.

That said,

AHCI - Advanced Host Controller Interface - this is a hardware mechanism that allows the software to communicate with the devices Serial ATA (SATA). It offers features such as connecting hot and native command queuing (NCQ).

IDE - Integrated Drive Electronics - IDE is basically the 'old' version of AHCI without connection to hot and NCQ. (It is usually used during the era the Parallel ATA (PATA) hard drives)

Now. Mode AHCI and IDE mode - what is - this? IDE mode is to give you the greatest compatibility with older operating systems. AHCI is as I mentioned above, a modern version of the IDE - use the AHCI mode if you are running recent operating systems (Windows Vista + and Linux kernel 2.6.19+).) IDE mode will allow you to connect older operating systems with SATA drives.

As I mentioned above, SATA is Serial ATA and the replacement of hard drives Parallel ATA (PATA).

RAID - this is a storage technology where combine you multiple disks in a unit of 'single', depending on the mode, there may be RAID-0 and RAID-6 and each with different hard drive configurations. I will explain the simple examples: RAID-0 , which is the distribution but no parity or mirroring, this means that there is no data redundancy, if there is a failure on a disc, it will cause the loss of data on the entire RAID array. Ex: You 0110 as writing the data, 01 goes on disk 1 and 10 goes on disc 2, allowing a faster data read/write access.

RAID-1- This is the opposite of RAID-0, which is mirrored without interlacing (no parity or the other). Basically, this means that you have an exact clone of disk 1 disk 2 disk 1 failure.

RAID0 + 1 is that both RAID 1 and 0 is, IE interlacing (write data simultaneously to two [or more]. disks more mirroring failure) the minimum amount of disks required for this type of installation is 4 IDENTICAL drives.

There is also RAID 2, 3, 4, 5, 6. That is just more implemented different configurations of distribution/parity/mirroring on disks.

That being said, your RAID mode will allow you for some type of RAID configuration, if you choose to do so.

Supplement: Many SATA controllers can enable AHCI separately or in combination with RAID support. Recommend Intel choose RAID mode on their motherboards, allowing also the AHCI, rather than AHCI/SATA mode for maximum flexibility (in the case that you ever want to build a RAID array), because there are a few problems that occurs, usually BSOD, when you choose a different mode once an operating system is already installed.

  • Can not start my old Satelite A100-168 or enter the BIOS settings

    Hi all

    My problem and simple to explain:

    The HARD drive led is not active.
    It is also impossible to go into the BIOS settings. The ESC key does not work.
    Everything is black.
    I tried to put a boot disk, but nothing happens.

    So is - anyone help me?

    Thanks in advance

    Message was edited: assignment has been translated

    From my point of view of the defective material, any party may cause the described problem.
    Even only one defective memory card could prevent the laptop to boot the system.
    Of course, also the dysfunction of the BIOS EPROM module would prevent execution of the power on self test and ultimately, it would mean that laptop may not illuminate correctly.

    I think that there is no general solution... parts must be checked; one by one.
    In the worst case, there is a motherboard problem and I think that in this case it s not worth to fix the unit because of the high cost of motherboard.

    You may or may not need to change the BIOS settings.  Assuming that you have a bootable CD with this tool, put it in your CD drive and restart the computer.  One of the 3 things will happen:

    1. the computer starts from the CD and you can follow all instructions you have Symantec.

    2 watching very carefully that the computer starts.  You may see a message that says something like "press any key to boot from the CD-ROM.  If you see this message, press a key (for example, the space bar) and the computer boots from the CD.

    3. watch very carefully that the computer starts.  You will see a message that says something like, "to change settings, press F1."  The key that you press on will be different depending on your particular computer.  It might be F1 or F10 or del key.  Whatever it is, press this button and you will enter the BIOS configuration utility.  From there, you can change the boot order to CD first.  Directions to navigate the BIOS Setup will be displayed on the screen, but they will involve using the button tab, enter, and arrow keys, because your mouse does not work in this utility.

  • EliteBook limited 8460p of the BIOS settings

    Hello

    I use a 8460p EliteBook. Now when I try to enter the BIOS settings, the computer asks for the opening of Windows account password or enroll fingerprints. Whatever I do, when the password is accepted and fingerprint recognized, it led me to 'read only' BIOS, only some parameters settings are editable. (see screenshots)

    I looked in all the menus in BIOS in order to activate the settings to change, but not glue.

    Maybe in the past, I used a kind of HP security software to lock down the BIOS settings.

    Please kindly help! I need to change the boot order, I recently joined a HDD caddy, he also start in the cart, not the first SSD.

    Thank you very much!

    Now, I understand why:

    When I press F10 to enter the BIOS settings, the system asks me if I want to get into the BIOS as a guest user, I was always move the blue highlight to the button NOT to open a session and after that he always asks me to enter the password / enroll fingerprints for nothing.

    This time I chose YES (or hightlight color is reversed), and I can access the complete settings in the BIOS.

    It's really weird.

    Hello Derek

    Use the F2 key to enter the BIOS settings and change the order of boot devices. This option is under the STARTUP tab. Otherwise, you can insert the recovery CD when the unit is turned OFF. Turn it on and immediately press the C button. keep it down for a few seconds and unit is forced from the CD/DVD drive.
