From what I can find about the Iomega card it has the ability to select
IRQ 5, 7, 10. In the old days IRQ5 and IRQ7 where used by LPT1 and LPT2
which leaves preferable IRQ10 to use. Then there is the question does it
use DMA Channels, AFAIK Iomega does not but take a look at the card and
see if it is selectable and choose 1 for a 8 bit card. And disable LPT
ports in the BIOS.
