    Hi everyone,

    I am running the original JP release of the Z BIOS, R3030C3 from 2010/08/26. What, if any, are the changes in R2170M3 and so on? Should I upgrade?

    Thanks,

    -pN

    Newer Z BIOS emulators allow you to switch on VT (for running VMware and similar) in the advanced menu. They also work with WIndows 7 for switching graphics back and forth, which the older BIOS versions don't.

    They also have disabled EFI boot, meaning you can't boot from an EFI thumbdrive, or partition your hard drive to GPT and boot from it. It also makes it far more difficult to enable the full Advanced menu.

    Oh, and RAM support has changed. One model (Z13? Can't remember) allegedly only works with 8 GB RAM if you run an older BIOS version, but for most of them, there will be no change.
