You need to prevent the ISA and PCI devices from sharing an
interrupt. If you go into the BIOS setup menus when booting your
system, the BIOS should have a way to specify which interrupts to use
for PCI. You should make sure that that set does not include the
interrupt used by your ISA device, apparantly IRQ 10.

This seems kind of suspicious, though, if you can't change the IRQ the
device is using.

How exactly does the DE-220CT probe? Is it possible to take the EPIC
card out long enough to boot successfully and use the card?
