EPC621D8A(asrock) can not patch CFG Lock.

CPU always idle at 3.0GHz when I use clvoer, but opencore works well.

I try to use AppleIntelInfo.kext or Hackintool get some info, but get Fault Cpu panic.

There are no CFG option in my bios. I try to disable CFG Lock with this guide.(Patch CFG Lock)

Manual and Bios about my motherboard.

I found some CFG Lock labels in bios image.(0xB3, 0xB4, 0xB5, 0xB6)

For example:

0x59B2C One Of: SAPMCTL_CFG LOCK, VarStoreInfo (VarOffset/VarName): 0xB3, VarStore: 0x5, QuestionId: 0x1835, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 DC 19 E4 19 35 18 05 00 B3 00 10 10 00 01 00}

0x59B3D One Of Option: Disable, Value (8 bit): 0x0 {09 07 B5 00 00 00 00}

0x59B44 One Of Option: Enable, Value (8 bit): 0x1 (default) {09 07 90 0D 30 00 01}

0x59B4B End One Of {29 02}

​

So, I get variable '0xB3' and value '0x5', but option is '0x0' or '0x1'.

'setup_var_3 0xB3' in GRUB shell get 0x06.

'setup_var_3 0xB4' in GRUB shell get 0x07.

'setup_var_3 0xB5' in GRUB shell get 0x08.

'setup_var_3 0xB6' in GRUB shell get 0x09.

​

It is so odd, I do not know what to do, any idea?

​

I try to set all variable to 0x00, still in lock mode.
