But that wouldn't make any sense since it works for my 8088w/CGA and the 
two cards don't conflict...

The only lines in my config file I can think of that may relate are:

(config.tel:)

video=cga                   # type of video screen
                             #    Legal values for video are:
                             #    cga,ega,pga,no9,hercules,ega43,vga50
                             #   Default is ega

bios=no                     # don't use slow BIOS screen access
                             #    bios=yes to reduce flicker on cga
                             #    bios=yes for TopView or Windows
                             #   Default is no

Couldn't hurt to turn on "consoledebug=1" too...
