I want to disable the integrated HighPoint 366 controller in the bios so I can use a PCI Promise Ultra 100TX2 controller for two ata 100 IBM hd's. I have a bios and driver issue in Win2k w/ the onboard hpt366 so I want to disable it so Windows 98,2k, and XP do not recognize it when installing the operating systems. I also want to disable USB to free up an IRQ. Why does Windows 98SE continue to recognize the HPT366 when I have no hard drives on the HPT366 controller. I have a SOYO 6BA+IV BX mb. I do not want Windows to recognize USB or the HPT366 onboard controller. The USB is set to no IRQ assigned. There seems to be no settings in the bios for disabling either? (Award 4.51 latest Soyo Bios w/ HPT366 v 1.28) I also had the drives running in ata 66 mode via the IBM utility when they were installed on the hpt366 controller. I formatted the partition and did a clean install of WIN98SE and see it ask for 3 mass storage drivers(should be one for the promise card) and it detects USB. I switched the drives back to ata100(via IBM utility) before I switched them over to the Promise controller and did the clean install.
