I'm sorry to clutter the bandwidth here... but since
the next thing that I have to deal with is setting up a CPU
server... is there a magic memory requirement for CPU servers
too?

There are no busmastering ethernet devices in the distribution;
the soundblaster and floppy use the generic DMA routines which
do the check and provide a buffer if necessary.

However, it's unlikely - Plan 9 does not do DMA to user
memory, only to kernel buffers. The space allocated by the
kernel at boot time for dynamic allocation is probably
within the first 16Mb.

What about devices other than disks?  If I get more ram for my

Speaking of that, don't pc's with isa devices need bounce buffers in
the device drivers in order to access more than 16M?

>>too?

8 mbytes and up is fine.  i've used cpu servers with only 4mbytes for
specialised functions (and it's probably possible to squeeze that further),
but you won't want to run very much on anything under 8 mbytes.
with less than 16mbytes, the system will page dramatically when you
link the PC kernel.
