I don't have any drive backplanes, and I pulled all of the cards from the slots, but that didn't help. Thank you for your suggestion though. I appreciate the help.
I actually posted my problem twice by mistake and I have another question open for the same problem. I didn't realize the moderators might take so long to approve the post and I thought something went wrong, so I submitted it again. The other question is "S3210SHLC BIOS Update Problem".
unfortunately I have got the same error message with an S5000XVN-board.
I previously was trying to do the update via a dos boot stick, getting "error 005".
Also no other add-in-cards - not even video (connected remotely to the system).
Any help would be very very appreciated...
