Bios settings for ASUS P8P67 WS motherboard

[jjshabadoo]

anyone have any insight in this uefi boot versus regular if you're using linuxcoin on a flash drive? seems it really will only boot in and then I can't ever reset it without a black screen hang on second boot.

I've got 4 5870's on x16 extenders and the powered molex into the mobo for extra power to the pci lanes.
ASUS P8P67 WS motherboard
1250w seasonic x1250 gold
4 5870's
pci x16 extenders
couple of scythe ultra kaze blowing through the backs of the cards
2gb ram
Intel celeron G530 cpu
16gb flash drive with linuxcoin final

have the bios on average power settings also figured maybe the low power thing could be screwing me.

I'm wondering mostly if the whole uefi boot has something to do with an ubuntu flash drive as the OS.
