Subject: BIOS update hung at 86%, what now?

thank you for the reply, good info and a couple things there i'll follow up on. thanks again.
as it happens i found another -- more direct -- solution to my problem. poking around i saw it suggested that for recent generation ASRock boards that do not have A/B BIOS control one should __try__ the following (no guarantees):
- clear CMOS using the 10-minute time-out + jumper approach .
- format a USB key with FAT32.
- copy the BIOS of choice to the USB key.
- reboot with the USB key in place.
- cross fingers and wait, "if you're lucky the firmware will load from the USB key".
that's what i tried and it worked exactly as described. there was a considerable delay between the time i powered up and the point at which something came up on screen -- the BIOS loading from the USB -- but it eventually did its thing and i was soon back in business. minutes later my OS was loaded -- fyi, linux -- and i was happily booting from disk like a real person.
my other ASRock board is a Z97 Extreme6 and it does have A/B BIOS control which has got me out of trouble a couple times. i guess i just assumed all their recent boards had it and i never checked before getting this new board. one lesson learned today: i'll NEVER again buy a mobo that doesn't have some version of A/B BIOS control, it ain't worth the headaches.
