Thanks for the history lesson.
Ric (who started out using linux on a brand spanking new 486 DX2/66 with
a whooping 16 megs of memory and a 15" multisync display, all for the
low low price of $5000.)
Check out the linux counter number below and then consider I was around
way before the counter came out. What I said stands, nor does anything
you wrote have anything to do with what I was asking him. We need to
know what exactly he's working with and if he has onboard video that
shares memory with the mainboard. That has been a problem at install
time since I worked at RedHat in 2000. But, thanks for all of the above,
I'm sure you got some sort of gratification from it. Ric
