[comp.sys.amiga.emulations] Why don't certain VGA cards work with the BB?

<CJC105@psuvm.psu.edu> (03/28/91)

Why do boards like the ATI VGA Wonder, and the Paradise VGA cards work with
the Bridgeboard while others don't?  For instance I have a board with a
TSENG4000 chip on it.  When the card is in the system, the PC will never boot
the first time.  When I do a hardware reset it reboots fine, but the 8K ROM
BIOS extention at D4000 disappears, thus I can not use the Janus utilities.
The card doesn't try to use this area of memory, so I can't understand why
the ROM is disappearing.  (Yes, I have the CGA emulation turned off).  Does
anyone know what might me going on here?  Thanks.
