I just opened two WAE-674 appliances.
Both go through post, find the RAID controller, and then stop when its looking for an OS. It looks like it will not boot from flash - I set the BIOS to default and still have the same results.
There is no option in BIOS to boot from flash... any ideas?
Can you please try booting and installing WAAS from the rescue CD? You can find instructions here:
