Solving the IDE controller problem in Windows
=============================================
After Windows setup (tested with Windows 98SE), there will be exclamation mark
at the Intel 82371FB PCI Bus Master IDE Controller in Device Manager and the
Primary and Secondary IDE controllers will be missing. To fix this, select
Intel 82371FB PCI Bus Master IDE Controller and click Properties. Then go to
the Resources tab, uncheck Use automatic settings box and scroll down the box
to see the last Input/Output Range (will be F000-F00F). Click it and then
click Change Setting button. You will see 0000-000F in the Value box. Use down
arrow to scroll to a free range (e.g. F100-F10F) and click OK. Then click OK
to close the property window. Windows will prompt you if you want to continue
- click Yes. Windows will find new hardware: Primary and Secondary IDE
controller (dual fifo). Close the Device Manager and reboot. The IDE
controller is now installed properly and you can enable DMA for your IDE
devices.
