Would anyone like to chat about BIOS modding? I have been analyzing a IBM/Lenovo RD640 server I got from a friend, its pretty stout, but its older Xeons E2600v2's could use a little boost. I have been doing poking around with a tool called UBU, can I extract the BIOS and enumerate the ROM's parameters to memory addresses in hex I found something like this: (edited)
0x1B691 Numeric: VID Override for Max Turbo Ratio, VarStoreInfo (VarOffset/VarName): 0x63, VarStore: 0x1, QuestionId: 0x54, Size: 1, Min: 0x0, Max 0xFF, Step: 0x0 {07 A6 9F 01 A0 01 54 00 01 00 63 00 10 10 00 FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00} 0x1B6B7 Default: DefaultId: 0x0, Value (8 bit): 0x0 {5B 0D 00 00 00 00 00 00 00 00 00 00 00} 0x1B6C4 End {29 02} This is a pretty normal parameter to find an asus desktop board, but it does not exist on the server.
So now I'm looking for someone with some experience to have a chat It seems I can dump the rom, flips some bits, flash the rom and it might change the parameter.
I have uploaded the follow items to google drive:
A1TSIMG.ROM, the latest official rom for the default board that comes installed on an RD640.
body.bin, setup_extr.txt, fit.dump, and csmcore from UBU

Any advice? Perhaps we can mod this one together? I appreciate your time, thanks for being around.

I could use a BIOS for the Optiplex 380 to support the QX9650 Core2Extreme CPU wwith CPUID 10676, and 10677 The G41 chipset lists support for this CPU, and I can get Voltage and multiplier control from inside Windows.
