Nearly there but
#1
Hi,

I have a silly Chinese PC (Haier 7G-3) and mostly everything is looked in the BIOS including basic features I need as the Intel (VMX) Virtualization Technology disable for unknown reason and invisible in the BIOS. So I extracted the IFR structure from the Setup module and I got this:

Code:
0x233AD Form: CPU Configuration, Form ID: 0xD {01 06 0D 00 8F 00}
0x233B3 Subtitle: CPU Configuration {02 04 8F 00}
0x233B7 Subtitle: {02 04 02 00}
0x233BB Text: Brand String {03 0B 96 00 95 00 97 00 00 00 00}
0x233C6 Text: Processor ID {03 0B 9A 00 98 00 99 00 00 00 00}
0x233D1 Text: Frequency {03 0B 9D 00 9B 00 9C 00 00 00 00}
0x233DC Text: L1 Data Cache {03 0B A0 00 9E 00 9F 00 00 00 00}
0x233E7 Text: L1 Instruction Cache {03 0B A3 00 A1 00 A2 00 00 00 00}
0x233F2 Text: L2 Cache {03 0B A6 00 A4 00 A5 00 00 00 00}
0x233FD Text: L3 Cache {03 0B A9 00 A7 00 A8 00 00 00 00}
0x23408 Text: VMX {03 0B AB 00 AA 00 AC 00 00 00 00}
0x23413 Text: SMX/TXT {03 0B AE 00 AD 00 AF 00 00 00 00}
0x2341E Subtitle: {02 04 02 00}
...
0x234D8 Suppress If: {0A 03 00}
0x234DB Variable Store Select: 0xC {25 04 0C 00}
0x234DF Variable 0x6[1] equals 0x0 {12 07 06 00 01 00 00}
0x234E6 Grayout If: {19 03 00}
0x234E9 Variable Store Select: 0xF000 {25 04 00 F0}
0x234ED Variable 0x0[1] equals 0x1 {12 07 00 00 01 01 00}
0x234F4 Variable Store Select: 0x0 {25 04 00 00}
0x234F8 Setting: Intel (VMX) Virtualization Technology, Variable: 0x61[1] {05 09 61 00 01 D9 00 DA 00}
0x23501 Option: Disabled, Value: 0x0 {09 09 04 00 00 00 10 00 00}
0x2350A Option: Enabled, Value: 0x1 {09 09 03 00 01 00 13 00 00}
0x23513 End of Options {10 02}
0x23515 End If0x23515 End If {18 02}

There is a lot of instruction "Suppress If: {0A 03 00}". I can find the part I am looking for in the binary using a Hex editor at 0x234D8

From here it should be simple to patch, if I can understand the bit to change and the value to use. Any helps, newbee here, sorry?
Thanks
