    If I do a search for slic with winhex is that a good start to see if it has one. Im pretty computer savvy, or is there another string I should search for?
    thanks

    You need to open the bios with cbrom, then extract the acpitbl module. you can search that with winhex to see.

    The modules are compressed, a search of the bios file proper will give nothing..

    I have a Gigabyte Gigabyte GA-P55M-UD4 using a Core I5 750 cpu.

    I notice that the BIOS file for this Award bios is 2048 KB
    Although the software says adding a new SLIC is succesfull, I am definitley not sure this is actually the case. Anyone have any experience as yet with this type of BIOS....?

    First, you are under a wrong assumption about bios file. Bios files do not come in one size fits all.

    That is utterly impossible due to the complexity of computers of this time.

    Yes, you bios will work but it will work on a USB BOOTABLE FLASH DRIVE....

    I have a gigabyte board and I flashed a 2.8 MB bios file on my computer using the HP SLIC 2.1 and everything is fine.

    So, I just modified your bios file using Award Tool 1.19 which came out today and I gurantee you that the file I have, though the size is 2.xx MB, will successfully flash your bios.

    I was just wondering if these rules are good to follow

    Method
    1) Flash, using the manufacturers recommended method, the unmodified BIOS of the same version. This allows the bootblock etc. to be updated.
    2) Mod the BIOS using the tool
    3) Flash the SLIC'd BIOS from DOS. Use only the /i switch. This ensures the bootblock is left intact and maximises the chance of a successful recovery if a problem was to occur.

    My bios from foxconn contains a autoexec file with multiple switches, Am I better off just doing a clean unmodded bios flash with default switches first, and then flash the modded bios with only /i switch?

    Flash with the switches supplied. Award flash does not use the /i switch.
    I dont feel the flash of unmodified bios is necessary, some do. It is preference. You do what you are comfortable with.

    I would mod the bios I had, rename it to original, and flash with DOS bootdisk and the autoexec.bat..done. You can flash with switches and not the bootblock. This is only very sensitive with MSI bios anyway.

    It is not a super big deal. If you can flash a unmodified bios, just run one through the tool and flash..:D

    911medic, as per your reply to TOMBO COMBO, i extracted the acpi table from my GA-P35-DS3L board using cbrom and "/Acpi extract" then searched using hex and didn't find a slic, to make sure the procedure is right i did the same for a modified bios and did find the slic word.

    Considering the above should i go 0+2?
    would the priority be:
    0+2
    ISA
    SSV3

    You will never find a slic table in a gigabyte board..not a PC anyhow..and certainly not that board. Maybe the X58 boards..:p

    you can safely use the SSv3 as defaulted to in the tool.Some report this as a slowdown. I have an ISA that works golden..I would recommend the ISA against the tool's default

    Never 0+2 as you will not get into bios to set defaults...:eek:.

    Only ASUS, Foxconn, ECS, MSI, consistently have SLIC code or tables in them..

    I was just wondering how do I get cbrom to spit out acpi. Im guessing through command prompt.

    cbrom /acpi extract c:\files\bios.bin

    would that be right?

    That info about never using 0+2 on gigabyte should be on first page for reference. As well as other known to be s**tty combos that brick the bios!
