The BIOS is not on the hard drive. The tools that are used by Compaq
to configure the BIOS though can be installed to the HD, booted from
a CD (SmartStart CD's) or from a set of floppies.

This is not ISA land. Sharing IRQ's with PCI is *NOT* bad.

Unless you really know what you're doing then do NOT do this.

Come on Alberto, you provided no dmesg and NOTHING to help you
out with. Is this system by chance a MP (multi-processor) system?

There are still some known interrupt routing issues on MP systems
and unfortunately all the fiddling in the world with the BIOS will
not resolve this issue.
