Resolving IRQ conflict between modem & nic

[fish051593]

Running UnixWare 7.1.1 on a Dell PowerEdge 2400 P3. Installed a Digi AccelePort RAS 8 port internal modem. Can setup ports & modems from within SCOAdmin but unable to access the device. Device Configuration Utility indicates an IRQ conflict with the network card. Both devices are camped on IRQ 11. Is this resolved by simply moving the modem to another PCI slot? Will DCU allow you to change the IRQ for a device or do I have to modify the BIOS when booting the machine? Thanks, in advance!!

Hi!
I do not believe that SCO supports internal modem. You
will be better off using an external modem on tty ports.
Multitec works best.

Thanks for your reply. I think I've solved the problem. Had to run the Resource Configuration Utility (RCU) which runs in DOS mode at bootup. This is a utility that is distributed with the Dell PowerEdge server. It allows you to modify the IRQ on various devices. Looks like it is part of standard procedure whenever you add another piece of hardware to the server. Trick was, there were no IRQ vacancies. We found the modem will function while sharing an IRQ with a SCSI controller for a tape drive. Both devices will function simultaneously.

Thanks,
