Changing component to the kernel.
Comment 3 Arjan van de Ven 2001-05-22 13:04:27 UTC 
Can you try adding "ide=nodma" at the syslinux prompt,eg

syslinux: linux ide=nodma

(don't type "syslinux:" yourself!)
Comment 4 Mickey Chandler 2001-05-22 13:53:12 UTC 
Just tried that.  No change.

Results unchanged.
Comment 5 Arjan van de Ven 2001-05-22 14:07:42 UTC 
Ok next try: mem=48M
Maybe the bios is lying slightly to linux about how much memory the machine has.
Comment 6 Mickey Chandler 2001-05-22 14:14:53 UTC 
That shouldn't be the problem.  In addition to the memory on the SIMMs, there 
is an additional 4M cache on the motherboard.  I've already tried switching the 
jumpers on the motherboard to disable the memory.  The BIOS will fail to 
recognize the additional memory (and go to 48M total memory).  

Same error.
Comment 7 Arjan van de Ven 2001-05-22 14:36:59 UTC 
Could you still try it? I set the value intentionally to be a bit smaller than
the actual memory..
Comment 8 Mickey Chandler 2001-05-23 03:30:48 UTC 
Ok.  Just tried it and got to the install.  Now it's complaining about lack of 
disk space for the packages I selected.  That's a problem I can fix.

Thanks!

That's a problem _I_ can't fix ;)
