When I try to set the resources for the floppy controller manually, it says "this resource setting cannot be modified", the same goes for the "motherboard resources" device that the floppy controller is conflicting with. I disabled the "motherboard resources" device and it made absolutely no difference. There's 2 of them listed, I only disabled the one with the conflicting I/O As for native mode using only one interrupt, when it boots in the pci device listing, it only has one ide controller listed on irq 15. I have more than one reason to believe the bios on this board has some issues. Advantech implies support for Win98, it seems they put all their time into refining it for Win XP and XPce. Maybe if I complain a little they'll fix the code. I really appreciate you guys helping out.
