Problem:
Windows 95 OSR2 will not recognise the hard drive controller
on my Tyan 1590.  Is there any way to get the Microsoft drivers to work.  

Solution:
Create the following inf file using your favorite text editor.

Save this file to a floppy.  I chose to call it viaide.inf

Reboot into safe mode.  Go into device manager.  Select hard 
drive controllers.  Remove the controller listed there (e.g. Standard Dual
IDE contoller)

Reboot.

Windows will attempt to redetect the hard drive controller.  Pop in your
floppy and let it use the "driver" stored on it.
If all goes well windows will detect a Via Dual IDE controller.  Then it
will detect a Primary IDE controller.  When it asks to reboot, choose no.
Then it will detect a Secondary IDE controller.  When it asks to reboot
choose yes.

=========
Problem:  I tried this, but there are yellow exclamation marks next to both
the Primary and Secondary IDE controllers, listed in Device Manager.

Possible Solution:  Go into regedit.  Goto 
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS
If you see a key that says NOIDE, delete it.  Reboot.
