400SC using with Win98se - HELP

Just got a 400SC with the 875P and wanted to load Win98se and use as a peer-to-peer server.  This computer does not like Win98. I went to Intel site and got the drivers for the chipset and loaded them. However, the video card is still in conflict with ACPI extension and Windows doesn't allow you to change the IRQ. Also I have other yellow flags in the device manager for other hardware. So, I took out the PCI card and went to a AGP card. Same problem. Anybody know how to get Win98 to work on this server?
