Some brief background info for the tech people:
The BIOS is a InsydeH2O BIOS with tianocore module compression. There is a big setup utility (multiple languages) stored at 0x111068 in the BIOS file (length) 0x9705C. If you disassemble it you will notice that BIOS does not check a VSS variable in the advanced options suppress-if condition (like on the VPC-Z1, variable 0x258), it refers to opcode 0x27 instead. This opcode returns true so the advanced options get suppressed completely. I changed this instruction to the opcode 0x28 that returns false so the full options get revealed. In the BIOS ROM, nothing more than one byte was changed (0x27->0x28 in the suppress instruction). 25% of the BIOS ROM appears to be changed, this is a result of the tianocore compression of the 600kib setup module.
Not ALL options are unlocked, some still depend on VSS variables but did not seem important to me. Have a look in the detailed Z2 BIOS options table here.
