@bibikalka1 Tested "nvme+ReBar+mc" on Z420, V1 1620 CPU (**Note:** I thought I was testing "nvme" previously, due to mixed up the extracted BIN files) . BIOS mod: V396/ME8/B2013 + 0x580000...

@bibikalka1 I've tested the "nvme" freature and it worked. Now Zx2 can boot directly off an NVME stick without the help of OpenCore! Will test your new mods when I...

@bibikalka1 Here is the test results (Note: limited to successful boot, no functionality test). Test 3. MEBALST1 "MEBALST1 xxx.bin" returned the following "ErrorLevel = 1" message:  Reboot did...

@bibikalka1 I redid the MEBALST1 test, as I likely lost track of the test conditions. This time, MEBLAST1 succeeded without error. I verified that 0x400 offset at ME region is...

@bibikalka1 I will test that later. But right, now I have another issue with my setup, which you may help me to correct - I encountered this error (see screen...

@bibikalka1 I did that, a couple of times. Same error. It is possible, that I picked the wrong backup BIOS. Will try again.

@bibikalka1 Did this test: 1) Start with a full working BIOS (this case: V393+ME8+BB2013. Powered on with FDO jumper ON, boot to FreeDOS USB. 2) "fpt -ME -f ME8_0396.bin", where...

If set FDO jumper ON, then we lost "Manufacturing Mode". FPT critical operation will fail. **C:\>fpt -f z2x_bck.bin** - Reading Flash [0x1000000] 16384KB of 16384KB - 100% complete. - Erasing...

@bibikalka1 By enable FDO jumper, I can write to ME region. By simply overwrite 0x400 byte with "0x01" allowed me to exit the "manufacturing mode", based on your discovery.

@bibikalka1 "backup 0" produced the following: (regions missing meant not able to access) FDOO0.BIN 4,096 BIOS0.BIN 11,468,800 GBEO0.BIN 8,192 PDRO0BIN 8,192 BIOV0BIN 458,752 BIOB0BIN 10,944,512 BBLK0BIN 65,536 Update: testing "fpt...
