Well KGP, here is something I have been poking around at about my asrock and msr.
Snippet of AppeIntelInfo
Code:
MSR_PMG_CST_CONFIG_CONTROL.......(0xE2) : 0x400
------------------------------------------
- I/O MWAIT Redirection Enable......... : 1 (enabled, IO read of MSR(0xE4) mapped to MWAIT)
- CFG Lock............................. : 0 (MSR not locked)
- C3 State Auto Demotion............... : 0 (disabled/unsupported)
- C1 State Auto Demotion............... : 0 (disabled/unsupported)
- C3 State Undemotion.................. : 0 (disabled/unsupported)
- C1 State Undemotion.................. : 0 (disabled/unsupported)
- Package C-State Auto Demotion........ : 0 (disabled/unsupported)
- Package C-State Undemotion........... : 0 (disabled/unsupported)
So I then opened my bios file in UEFITool, instead of searching for CFG Lock I instead searched for MWAIT. It found a match, so i extracted it via ifrextract.
Snippet of MWAIT
Code:
0x391DA One Of: Monitor/Mwait, VarStoreInfo (VarOffset/VarName): 0x7D, VarStore: 0x1, QuestionId: 0xCF3, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 44 11 45 11 F3 0C 01 00 7D 00 10 10 00 01 00}
0x391EB One Of Option: Disable, Value (8 bit): 0x0 {09 07 4B 0A 00 00 00}
0x391F2 One Of Option: Enable, Value (8 bit): 0x1 (default) {09 07 4A 0A 30 00 01}
0x391F9 End One Of {29 02}
Do you have any comments or suggestions about this finding? Or any other person with some knowledge.
Thank you for your input.
