Software mapping of frame buffer from 8M to 16M
Video display memory: 3/4 MB buffer, Dual port VRAM.
System requirements:
PC AT or higher.
VGA card with compatible feature connector (call 1-800-998-LABS to verify
compatibility).
16bit slot.
DOS 3.1 or greater
VGA or multisync runing 50-70Hz with horz scan of 31.5Khz.
RAM must be less than 16MB.
I was quite interested in one of these cards till I noticed the last caveat.
On my 486 the choices are 8M -> 16M -> >16M thus having a video blaster will
limit me to 8M. I would like to be able to run Unix out of
another partition and X in 8M is grim. The video blaster card locates its
memory somewhere between 8M and 16M and interferes with any memory that
is located in the same area thus restricting the system to <16M.
