Predator G3620 - Booting to USB/CD?

xeleion — Sun, 10 Mar 2013 15:33:24 GMT

I have a Predator AG3620-UR12, just purchased about a week ago. I've had a couple of random restarts and decided to test my RAM with memtest86+, but couldn't boot to USB or CD. Upon a bit of research, I figured out this most likely has to do with the newfangled UEFI stuff, but I can't figure out exactly what to disable in the EFI settings/BIOS for the computer to boot from USB.

Whenever I try to choose different boot devices, it always fails to find anything except the hard drive, even with both a bootable CD and USB drive availabe.
I tried disabling SecureBoot as well. In addition to increasing the startup time at the main boot screen to 4-5 minutes, it still didn't find the bootable devices.
Both the CD and the flash drive show up in Win8 just fine.

Anyone have any experience with this machine or a similar model (I assume similar models will have the same BIOS)? Also, has anyone experienced random restarts or RAM issues?

Bumping, as I still haven't figured this out yet. Someone has to be experiencing similar issues.

I've figured it out.

On the AG3620-UR12 mobos there's an option to called 'Legacy OPROM'. I had to do a bit of research to figure out what OpROM is. As it turns out, it's a UEFI feature that follows older BIOS protocals, so that legacy devices are compatible. Once I enabled it (it was disabled by default) everything booted up just fine.

I'm going to take some time to research UEFI and everything that it does. There's a site dedicated to it - http://www.uefi.org
