[SOLVED] MSI X2-108 (MS-9238 v3.xx)

Cool! No changes to BIOS are needed!
You can use your CPU with SYMCMOS:
(0219) - Execute Disable Bit
0 - Disable 1 - Enable
(021C) - Thermal Management 2
1 - Disable 0 - Enable
P.S. Can you enter to Advanced Processor Options. Any changes?

Thank you for your help and patience.
Cant look right now at BIOS setup, server is super loud, and kid is sleeping already)
Is it possible to make it human friendly, to unlock that options in BIOS setup or maybe make it ON in default CMOS settings?

[DeathBringer]

I think it's a logical error in BIOS code. But I can't find it .
P.S. Execute Disable Bit & Thermal Management 2 are enabled in default BIOS settings, but they are disabled in first start with new CPU. BIOS define incorrectly CPU capabilities.

Looked at dissasm of SETUP00.ROM, no way i can trace back to code which checks what futures are available )

[DeathBringer]

I'm still waiting news about changes in Advanced Processor Options after SYMCMOS patching...

[SimpsonsFan]

Sorry for delay. Options still not available after symcmos patching.

[DeathBringer]

SETUP00.ROM uses external calls to define CPU capabilities. Error in somewhere else.
So you must use SYMCMOS instead of BIOS setup.

[SimpsonsFan]

Is it possible to add some OpROM that can enable that futures atleast in CMOS settings?

[DeathBringer]

I've found code in module BIOSCOD06.ROM that verify 0219 & 021C CMOS settings.

Code:

DA08        mov     ax, 219h
DA0B        call    far ptr 0F000h:3661h
DA10        jnz     short DA49
...
DA7E        mov     ax, 21Ch
DA81        call    far ptr 0F000h:3661h
DA86        jz      short DA8C

You can change these conditional jumps to unconditional. Simply replace one byte on address DA10 to EB. And replace one byte on address DA86 to EB too.
I've done it and you can download result.
Use Phoenix BIOS Editor to replace module BIOSCOD06.ROM.

Thank you! I'll check it ASAP.
