    Post Generic Bios Mod HOWTO

    Okay, here is a generic HowTo so you no longer need to wait for other people to release bios mods. I'm not going to cover adding new features or showing hidden ones by default, but I will show you how to upgrade embedded firmware (IDE/SATA Raid, PXE boot roms, etc).

    WARNING! MODIFYING THE BIOS IMAGE PROVIDED BY YOUR MOTHREBOARD MANUFACTURER MAY NOT BE SAFE. IF YOU MAKE A MISTAKE, YOUR SYSTEM MAY BE DISABLED. THE FOLLOWING PROCUDURE WORKED FOR ME, BUT IT MAY NOT WORK FOR YOU. USE IT AT YOUR OWN RISK. I AM NOT LIABLE FOR ANY DAMAGES THAT MAY OCCUR.

    First, you need to identify what hardware your motherboard has, and obtain:
    1) The latest BIOS from your motherboard manufacturer.
    2) The latest firmware/bios for your onboard devices.
    • ITE RAID BIOSs may be found at www.ite.com.tw
    • Silicon Image RAID BIOSs may be found at www.siliconimage.com
    • For other firmware, just search around. You ought to be able to find it.

    3) A recent version of cbrom (at the time of this writing, version 2.15 works well). NOTE: The 2.x versions are NEWER than the 6.x versions. Search on google for this one. It should be easy to find.

    Extract everything and stick it all in a single directory. Open a command prompt ("cmd.exe" in XP/2000, and "command.com" in 9x) and change into the directory with everything in it.

    For the remainder ofthe HowTo, I'll be using cbrom215 to refer to the cbrom executable. If you have a different version, use its name instead.

    Now view what's currently in the bios image (which I'll call bios.bin)
    Code:
    cbrom215 bios.bin /D
    You should see something like this:
    Code:
     No. Item-Name         Original-Size   Compressed-Size Original-File-Name

    What we're interested in are the PCI ROM[] entries. I have a Silicon Image SATA Raid controller and an ITE Raid controller. They show up as 4200.bin (PCI ROM[A]) and ITE4212.ROM (PCI ROM[D]). PCI ROM [B] and [C] are the pxe boot roms for my intel and nvidia lan cards. None of this is incredibly important, but it's fun to know.

    Next, we want to replace the old, included rom files with the new ones we just downloaded. So, to update my SiliconImage Raid controller, I would type:
    Code:
    cbrom215 bios.bin /PCI 4247.bin
    Where 4247.bin is the new bios/firmware I just downloaded. You should see a message something like this:
    Code:
    CBROM V2.15 (C)Award Software 2001 All Rights Reserved.
    Adding 4247.bin ..... 51.5%
    Now when I view the debug output again, I notice that 4200.bin has been replaced:
    Code:
     No. Item-Name         Original-Size   Compressed-Size Original-File-Name

    You can follow the same procedure to update other rom files. When you're done, bios.bin will have the latest firmware images included in it, and if you flash it and reboot, you ought to see that they have taken effect.

    I hope this helps!

    Re: Generic Bios Mod HOWTO

    This was done by the man who taught me to mod bios, the man is a guru.

    Modbin Tutorial

    Cbrom Tutorial

    These links are for learning purposes nothing more. They are links to 2 different tutorials pretaining to the above topic.They are alil better explained on the tutorials provided then the one above, Although it is a descent explanation, I felt it would be better to show a more thourough one. No offense intended but when it comes to peoples systems it has to be as thorough as possible for they people whom are attempting these mods.

    Re: Generic Bios Mod HOWTO

    Well it'll take some of the demanding of things to be done to a minimum, folks can actually try it themselves, then we that mod bios can actually "help" instead of doing the actual mods, unless absolutely needed.

    Re: Generic Bios Mod HOWTO

    perfect all I need now is a fix for the multiplier on my 7n400 Pro 2 Rev. 2 Board.

    The 10 and 10.5 multi's dont work and Ive read that you can fix them by hexing the bios file....

    But the turtuoral wassnt in good english and I had a hard time understanding it.

    Re: Generic Bios How To

    This is an old topic I know but I'd thought I'd blow the dust off it.
    The links that Wild Child posted no longer exist - so this site seems to be the one decent spot on the web that shows how to use CBROM.

    Something that Kogur forgot to put in his guide is that before adding the new component BIOS file to the motherboard BIOS file you have to remove the previous component BIOS first. I've edited the instructions above to reflect this below - the relevant bits are in Bold.

    --------------------------------------------------------------------------

    What we're interested in are the PCI ROM() entries. I have a Silicon Image SATA Raid controller and an ITE Raid controller. They show up as 4200.bin (PCI ROM(A)) and ITE4212.ROM (PCI ROM(D)). PCI ROM (B) and (C) are the pxe boot roms for my intel and nvidia lan cards. None of this is incredibly important, but it's fun to know.

    Next, we want to remove the old, included rom files. So, to remove my SiliconImage Raid controller, I would type:

    Code:
    cbrom215 bios.bin /PCI release
    
    CBROM V2.15 (C)Award Software 2001 All Rights Reserved.
    PCI ROM - - - A : 4200.bin
    PCI ROM - - - B : 8169pxe.082
    PCI ROM - - - C : ITE8212.ROM
    Enter a choice:A


    Next, we want to add the old, included rom file with the new ones we just downloaded. So, to update my SiliconImage Raid controller, I would type:

    [QUOTE]
    Code:
    cbrom215 bios.bin /PCI 4247.bin
    Where 4247.bin is the new bios/firmware I just downloaded. You should see a message something like this:

    Code:
    CBROM V2.15 (C)Award Software 2001 All Rights Reserved. Adding 4247.bin ..... 51.5%
    Now when I view the debug output again, I notice that 4200.bin has been replaced:
