We just received two machines using Pentium II motherboards (Intel PD440FX) with AMI BIOS 1.00.04.DT0. The problem is the BIOS configures the PCI SCSI and Ethernet devices to share the same IRQ. While WindowsNT device drivers appear to have no problem with this (IRQ sharing is part of the PCI spec), some Linux and FreeBSD drivers do. There are some free IRQs, but the BIOS assignment appears to be non-user-configurable. I've looked for a SCU (System Configuration Utility) program for this motherboard on the Intel developers web site without success. Moving boards around and disabling the COM, USB, and LPT devices didn't help either. The current solution is removing the SCSI controller and going with an IDE disk. I'd appreciate any other suggestions or pointers to a SCU program I can use! -- Jon <jinouye@cse.ogi.edu>
