not sure if it helps, but when I updated to this BIOS version, I was even unable to boot from any of my devices (including DVD). I had to switch back to 0039 or what version it is.
Anyone having a similar problem? I seem to be able to duplicate this issue every night. I have Raxco PerfectDisk installed and according to the event log, it appears whenever a consolidate free space pass is made on the drive that is on the controller, it disconnects (along with the DVDRW).
I got the same board, and mine still disappears under heavy load even with 060 bios.
It will only reappear after restart. OS is Windows 7 x64.
Anyone experiencing the same?
