I have a 2350, tried to upgrade bois to A02 did not work. I went ahead and downloaded the windows update for XP Pro which installed fine. I then tried the floppy again with the bois upgrade this time it seemed to work when I rebooted the machine it never came back on.
This is what the manual says:
Another type of failure has occurred.
Check the computer message that appears on your monitor screen.
I would try disconnecting all cards and see if that helps.
Otherwise you might have a motherboard problem.
