Mod Your Own Bios / Discussions on BIOS Transcoding

Good idea to get all the info together:

Please make clear that the isa method works genarally. Not only for Gigabyte bioses.The pubkey / marker method mainly for Asus boards.
But you can try both methods for ALL Award bioses.

Phoenix:

-Open bios.wph or bios.rom with Phoenix BIOS Editor
The bios will be decompressed, all parts are in Phoenix BIOS Editor\TEMP folder now. You can open them with winhex to edit.

-Search for "SLIC" to find a already present SLIC tabe. If found DO NOT modify try to activate first. If it doesn't activate check Everest. No SLIC present at Everest, modify bios

-Copy file with slic table into Phoenix BIOS Editor\TEMP and rename it to the next higher ACPIn.ROM. (n ist the next higher acpi number).

-Open rom.scr with notepad and add a line "ACPI ACPIn.ROM -X", save it.

-Search for "RSDT" and if present "XSDT" string.
Overwrite string next to "RSDT" and "XSDT" with your OEM table and OEM table ID you want.
They are usually found at BIOSCOD1.ROM file. Save changes.

-To enable save button (now is gray) change something random in Phoenix BIOS Editor and restore its original value

-Save bios and check log for errors

If the bios shows log errors on rebuild, be careful testing.

Note:

There are bioses that contains slic table already, but it is not active or only mapped a half. There are built-in routines that change the OEM table id to a fixed one. It's difficult to find them and to disable.
I'm working on this issue and found a way regarding already present SLIC. To circumvent this "problem" do this: Rename the already present SLIC to TEST by editing the SLIC string (title / name) of the ACPI table to TEST. Search for all further SLIC strings at ALL MODULES. (Found sometimes at MOD_5100.ROM) and rename it to TEST as well, except those SLIC strings that are a part of the SLIC table itself!!! Now insert a complete new SLIC table as described above. Done!
The clue: The original table is named now TEST table and is mapped incomplete into RAM while a COMPLETE new SLIC table is mapped into RAM as well!

To circumvent the "problem" with a locked OEM table / table ID you have to disable the code that makes those fixed OEM table / table ID equal at RSDT = XSDT=SLIC or even at ALL tables. It's a routine best to find with a debugger....difficult to explain here........at Sony Vaio I never found it so far..........If somebody is interested please PM me.

Always keep in mind: Some of the mods are not working cause of this issue. Some of the mods brick Laptop without any known reason. Newer results are that it probably is caused because of PBE isn't decompressing the modules completely (data lost). To check, repeat it more times and compare the decompressed modules.........

This is the corresponding certificate which you need to activate Vista after you flashed the modified bios.
