Method:
Well I 've been playing a little bit with assorted chmem settings
Xdm, xinit, and Xorg. I have an ATI rage II card in that machine and
From what I saw in the log for the auto-probe, it appears to have a 2048
KB video RAM.

I 've knocked Xorg to about 12 MB memory size and it starts to a point
(No out of memory anyways); now I have video resolution setting/Sync
Errors I think. I have to use 1024x768, because its an older flat panel
Screen and anything less is too fuzzy to look.

I'll keep juggling and see what I can figure out. So far though, using
Xdm, startx, or xinitDoesn't work yet, but starting Xorg on its own:

Xorg-verbose 3-logverbose 3

At least tells me more that I knew before. If I Can Get X (Xorg)
Start, then the rest shoshould fall into place I hope.

The problem you're experiencing is caused by the fact that minix
Currently doesn't have a virtual memory system. As a result, X-Windows
Must rely on real memory to operate. Normally, you 'd just be able
'Chmem + 100000000/usr/x11r6/bin/Xorg'// Set Virtual Memory Processing
To fix the problem, but you
Don't have 100 megs to use for the data segment. And since the system
Can't swap to disk, you run out of memory.

You can mess with the chmem command to see if you can set the X binary
To a reasonable memory size, but otherwise you're probably going
Have to wait until minix3 grows up just a little.
