io/irq conflict detection/resolution

I'm having problems installing Win2K as a guest OS in VMWare(tried 2.0 and 3.1). I'm running RH linux 7.1 with default 2.4-2 kernel. What happens is during the final steps(specifically under "performing final tasks->Registering Components(about 80% of the way through)) my PC completely locks up(no hard drive activity not even the keyboard will respond). This happens every time, at the same point.

I dual boot on this system to Win98, and I've seen a similar problem(ocassionally), usually when I print. I'm guessing there's some sort of I/O or IRQ conflict, or possibly a hardware problem somewhere. I've tried tweaking the BIOS, to no avail..(I have an Amptron K7VZA MB if that matters at all)

So anyways, I would like to find where the problem lies. I'm fairly knowledgeable in Linux(and Windows), but I've never seen such aproblem on another system. I was wondering if there's a way to do a scan of all I/O ports to see what the problem may be. It's a USB printer that I'm (almost) convinced is the culprit. Any troubleshooting ideas/tools would be greatly appreciated.
thanks!

It could be the USB printer -- I have had USB devices lock up my Linux system before.  Simple way to tell is of course to disconnect the printer and see what happens.

I would suspect a memory problem as much as a PCI problem.  Can you remove your memory and put in a new memory stick maybe borrowed from a friend just to test?
 
Also, I would upgrade to the most recent BIOS on your motherboard.

But, to answer your question, /proc contains quite a bit of information about your irq/io ports, and dmesg should show error messages from drivers.  Try these and post the resulting pcidata.txt here:

cat /proc/pci >> pcidata.txt
cat /proc/usb/devices >> pcidata.txt
dmesg >> pcidata.txt

These should give us enough information to find out if there are any obvious resource problems.

It was the BIOS. Got the latest upgrade from Amptron, and everything's going smoothly. They do cite some USB bugs in earlier BIOS's(v. 3.0 in my case).
