Sure, because you're hanging the expansion bus and God-knows-what-else with the 590 turned off. The only thing you can do is shut down, disconnect the 590, and reboot. Actually, I'm surprised it gets as far in the boot process as it does. > I was under the impression that if there is bad memory on a board, > then it is mapped out during boot.

Absolutely. The 590 is on the expansion bus, which you hold in weird states if the 590's power is off. > thomas@diku.dk, Thomas Nikolajsen, CS.
