Hi
I recently acquired a HP Z620 and a HP quadro K4000 from a Z820 to replace the K2000 that came with the Z620 everything was fine until I set tried changing the option ROM to efi, now when I reboot the monitor remains in stand by untill windows starts, so I can't access the bios to make any changes, just wondered if anyone has any idea what's happening.
Thanks in advance
Mark
