Thank you for confirming that there is a problem here.  I'd like to see that
patch.

On the other hand, I'd also like to be able to fix the BIOS problem since it
might help when I run the machine under Windows.  Does anybody have any
technical information about how I might be able to do this?

Hmm. I'll look into it.  That was on my short list to be done after the IRQ
problem was cleared.  From what you are saying, this package should help clear
the problem.  If that does not help, I'll try the boot line parameter that 
Charles Taylor mentioned.

Thank you for the information.
