In other words, your }16-bit VGA will act like an 8-bit VGA. You've got it backwards. Any 16-bit card in a double segment forces all cards into 16-bit accesses. This means that you will have to set your VGA to 8-bit operation in order to be able to use the mono board (unless you can find a 16-bit mono adapter--let me know if you do!). If you leave your VGA in 16-bit mode, you'll get some interesting effects as all the attribute bytes written to the mono board get sent to bit heaven.... -- {backbone}!cs.cmu.edu!ralf ARPA: RALF@CS.CMU.EDU FIDO: Ralf Brown 1:129/3.1 BITnet: RALF%CS.CMU.EDU@CMUCCVMA AT&Tnet: (412)268-3053 (school) FAX: ask DISCLAIMER?
