As far as I know, dz_atkill is not part of a current release of dzcomm. It
may have been part of a pre 0.7 release, which was before I took over
maintaining the package. If you still have a problem after:

1. completely installing (a current version of) allegro from scratch without
   dzcomm present,
2. adding (a current version of) dzcomm and trying to get it wokring,

I'll see if I can help out.

throw that piece of crap out the window and get a real video card... lol
Even if it's a new piece of crap at least it should support vesa properly..
like those $30 8 meg AGP cards.

I have a 2mb PCI Stealth 3D 2000 which is alright when it comes to vesa (as
long as I use S3VBE20 ) but I wanna get an AGP card... AGP makes a huge
world of difference as far as I've seen when it comes to software

drawing tiles across to a double buffer, then blitting that double buffer to
the screen, I can get 120 FPS in windows in 640x480. In dos that can go
nearly as high as 150 FPS. But that sucks. My friend has AGP and he gets
over 400 FPS.....

And he's not that much faster then me... I have a 291 K6-2 while he has a
433 Celery
