Yes, but keep thinking.
I've even set all devices to boot from CD. Its normal now with CD as first boot device.
What happens is that we get all the way to: Verifing pool data, then a line comes up with "Boot from CD/DVD:" then nothing works, PS2 KB, USB KB,
and then a dialogue box says: Boot MGR Missing, Press Cont, Alt, Delete to restart, and around we go. All KB work on other computers and on the
splash screen here.
This a 3yr old Gigabyte 5 series that was originally set up as a gaming machine. The CDs are IDE, although I tried SATA drives earlier, the HDD is a SATA drive.
This computer quit a year ago with malware. I was busy and replaced this MB with a 77 and i7. I have time now, and I'd like to repair this one.
I think the keyboard is somehow being disabled when given the option to Boot from CD. Just a theory.
