Looking at the BIOS manual on their web site:

you can try toggling a few of the options: Try switching OnBoard IDE Operate
Mode between Legacy Mode and Native Mode. If the kernel and the actual
device disagree here, that could cause IRQ delivery problems. You can also
try playing with the "Plug& Play OS" setting.

The machine with me has no "OnBoard IDE Operate Mode" option. "Plug&
Play OS" has been tried with "Yes" and "No".

If the kernel and the actual device disagree, could it also "break"
the ethernet adaptor? This also doesn't work.

Well, the ethernet adapter would likely be a different problem. Do you get any interrupts showing up in /proc/interrupts for either the disk or the network adapter?
