My old motherboard stopped reading the USB thumb drive this week (I tried all ports and all the USB headers, so I guess the USB controller died). So I re-purposed an ASUS M4A78 Pro motherboard that I already had. I upgraded the BIOS to the latest version. Now getting this board to boot from USB drive ia a PITA!! Since it appears on the hardware list, I assume someone has figured this out. The problem is that I have to press the F8 key at boot BIOS flash screen in order to get a boot menu that I can select the Unraid USB drive, thus requiring keyboard and monitor and me being physically present to boot the box.
Here is what I have tried:
Upgrade BIOS to latest from ASUS
Disable Floppy Controller (no big deal, but I could not get USB to boot at all unless I did this)
Made "Removable Device" first in BIOS boot priority list
Removed all other possibilities from boot priority list
Any ideas on what else to try?
Thanks,
