Hmm, 0603 is the earliest bios version Asus has posted on their site, and it's listed as "first release bios."
So I can't even go back that far.
I'll try flashing 1103 when I get home & if that doesn't make the boots quicker, than it seems like that's what it'll have to be until they either fix the bios or I find the magical setting hidden in the bios that's causing these boot anomalies.
I can get past a slightly longer boot time, it's not that life-changing, and the SSD performance at an OS level seems to be blazing fast, so my only concern is that there's still an underlying problem somewhere that will rear it's ugly head later.
I have no idea, for instance, why I can't press tab to see what's going on during the post. Or why 5% of the time is doesn't want to recognize usb devices on reboot.
