To elaborate your BIOS may have a setting to allow the BIOS to configure hardware instead of allowing the OS to do it. Look for "enable/disable PnP aware OS".
The downside to this is limited resources. You will need to disable all unused hardware.
You may need to try both ISA slots to get the 220 option. As I recall, sound may want to use 220.
Worth a try.
