Hello all,
Well, as a diversion from schoolwork, I have been playing with the
VS2000's mono video stuff, and have something which almost (well, not
really) behaves like a graphics console. I have a question,
though, because I've never really done anything like this before.
All I've done so far is to put some graphics console stuff into
the dzcnputc() call in dzcons.c. What I do is write the character passed
to dzcnputc() to video memory in the right place (& deal with scrolling
and BackSpace, etc). I'm still using my VT220 as a terminal, of course,
but now I get nice big letters on my monitor as well. (Well, they're not
that big. I guess I'm getting fairly small letters on my nice big monitor
...)
The problem is this: if I try to map too much of the video
memory (a little past half, I think), I get a kernel panic with
kmem_suballoc: bad status return of 3.
panic: kmem_suballoc
What, exactly, is a 'bad status return of 3'?
Okay ... that's it, time to start playing with LK201 stuff now. (well,
it's either that or Calculus)
Thanks,
Nathan Schepers
