The massive interrupt sharing is caused by ACPI, so you have to tell you system in the device manager that it's a standard system and not an acpi system.
If you want to do this with your current system, go to the device manager and update the system driver to standard pc.
If you want an absulutely clean install, press F5 when Win2k gives the F6-option to install a SCSI/IDE driver, and choose the standard pc system there.
Note that you'll have to activate APM under the energy options of the control panel in order to make your system automatically shutdown.
