mouse vs. xenix 2.3.1

[David F. McCune]

I am having trouble using the built-in mouse on my
ATI VGAWonder card with Xenix.  The mouse works just
fine under DOS, set for interrupt 5 and i/o address 23CH.
I have used "mkdev mouse" to create the mouse drivers under
xenix (Microsoft bus mouse compatible), but once I boot
up xenix and try "usemouse" or vpix, I get no response from
the mouse at all.  I've tried a large variety of different
interrupt/address combinations.

Has anyone had/solved a similar problem? Any advice would be 
much appreciated.

Thanks!

David
