The PC164 has four PCI slots, two 32-bit, and two 64-bit. This
evening, I tried to put a 32-bit card into a 64-bit slot (I'm out
of 32-bit slots). I tried a Matrox Millennium II (4MB), and later
a Qlogic ISP 1020 SCSI controller.

Both cards work fine in a 32-bit slot, but when placed in a 64-bit
slot, SRM v5.5 blows chunks.

What have I missed? What am I doing wrong?

	curious,

When a card is placed in either 64-bit PCI slot, this happens:
