Hi all,
I have a program, not xPDF; rather QV; (which I downloaded after hearing
about it here/on the old list via John Oram), that I want to try to run on
my PC-AT 386DX __
according to it's documentation, QV, in order to play MPEG movies/video?
needs a 387 math co-processor chip, forgive me for being lazy, yet could
someone translate bernie's note below... I didn't know I have a LINK
command line... what is a LINK command line?? do I need to "link QV to
memory", like I used to in programming class after compiling fresh code,
now, as part of emulating a 387 chip?
I just want something simple... as simple as plugging in a 387 chip then
trying to run QV
1. I want to download the file(s?) emulator
2. put it/them in a directory like I "flopped in" QV
3. adjust CONFIG.SYS and AUTOEXEC.BAT appropriately
4. download some MPEG files
5. then run or attempt to run QV
can someone help with this??
