After upgrading the motherboard to BIOS 4.60, the computer goes directly in to the OS, doesn't show the BIOS or POST screen so I can't access the BIOS settings.

I've tried using windows flash but the flashing program just exits after running the check, doesn't seem like I can downgrade.

I've tried downloading the UEFI tool to go straight to BIOS, doesn't work.


Anyone have the same problem or have tips on how to deal with this?

Thanks

or plan B

turn it off

unplug the boot drives and then try to get into bios and turn off fast boot

I'll try unplugging the HD and see if BIOS comes up

Figured it out! 

For some reason when I had a video card in slots 3-6 it wouldn't show the BIOS screen but if there are less than 2 video cards and they're in slots 1-2 it boots.

Next problem is to get the motherboard to work with 6gpus
