Steve, Here is some of the info about my machine. Sorry it took so long to get back to you.

Here is the information off the top of the chips. The first and the last one are responsible for routing interrupts in the system. (M)AMI 9511ATY 6721-502 Intel (C) 94 620368-001 Intel(R) PCIset S82375SB S Z955 16A8EF1070 JAPAN9527EAI (C)'92008 Intel(R) PCIset S82374SB S Z892 16T6F1004 JAPAN9520EAI (C)'92037 > > What do you need to know?

Well, I couldn't get this to compile on Linux, which is what is loaded on the machine at this time. It doesn't have the debug kernal either. Sorry. > Also, give me your 'dmesg' output, as well as the part #s of your IO APICs > and chipset if known. Here is the dmesg output....
