Hi BDMaster,
i have managed to update the bios but i dont seem to have any control over the sata controller settings or ahci modes, there is only the power management and a little on the CPU that i can change, how come the other settings are not displayed ??
Would you be able to check the original bios for advance menus for me please?

I also found this i dont know if it helps,
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.

Yes You right and I define IFR mods like More Options (Camiloml and TTAV134 used this word) !
We can unhide some Options modifying the opcodes and You have done !
The Bios file became different if You change 1 byte only as LZMA compression change all into !
So what do You want yet from me ?
Regards

Hi BDMaster,
i want to be able to modify the extra settigns like the raid controller (set up raid 0 and 1) and see all the settings which have been restricted, by sony including i/o settings and graphics.
if the bios file changes does this have an affect on the system settings?
I have seen this video on youtube with a vgn-z owner who has all unlocked settings of the bios and that is how i want mine, full control.
