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.
The lights come on and I can hear the fan running but I do not get a bois start up screen nor do I hear the hard drive spinning.
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.
So at this point I might be better off to just change the motherboard, what are your thoughts on that idea.
