Irq conflict

I have a NEC PowerMate 75.  When I install a modem card
(supra 288i) I get an irq/io error.  Also says motherboard
error #07.  Then the b drive no longer works.  This seems
be just an irq conflict. I am using an ISA expansion slot
but I don't know how to redirect the IRQ.  I assume the
modem should work with and ISA slot.  Any help would be
great.  Thanks in advance.

Are you using W95?
YOU WILL SEE JUMPERS ON YOUR FAX/MODEM you can change them to pnp an let windows95  take care of irq setings. You also can go to bios and disable your com ports and you will see which com por is used by your modem and then change your com ports or modem setings com1 03f8h com2 02f8h com3 03e8h com4 02e8h com2 and com4 use irq3 and com1 and com3 irq4
