Me too. ATI VGA Wonder/512K w/NEC 4D monitor running under 386 Xenix 2.3.2.

Before upgrading to a 386 system and Xenix I had the adapter card and monitor
installed on an ancient 286 (Zenith ZF-281) running the Rev K version of 
286 Xenix. When going from DOS to Xenix (I had both partitions on the HD) I 
had to make sure the ATI card was setup to look like an EGA screen because 
I'd get nonsense characters if I tried to boot xenix w/the adapter in VGA mode.
Since there's a configuration program that you can run under DOS to set the 
EEPROM for this, there's not much problem since I'm sure you'll get at *least* 
EGA resolution out of your card. 

As for the 2.3.2 version of 286 Xenix, I can't say since I've only run it 
as a 386 setup, which works just fine.
