Paul and Vince, I don't think this is a problem with the IBM BIOS. It is actually very flexible, and allows one to assign one or more IRQs for PCI devices. Try the following command: ps2 pciirq 11 10 9 ... [where numbers are free IRQs] Running Win95 on a 600, or WinXP on a T23, I've had no device problems even though all the PCI devices are on a single IRQ. I think you have a FreeBSD OS/device driver/app problem here.
