I am unsure if either support 1520's.  I can not comment.

OS/2 can reside SOLELY on the first or second disk.
DOS has to be on the first disk.
Linux (the last time I installed it) could reside on the second disk.
*BSD (the last time I installed it) could NOT reside on the second disk,
but it's swap and any other extra partitions could be on disk2.

120 meg = disk 1
40 meg = DOS
75 meg = *BSD /'s
340 meg = disk 2
75 meg = *BSD swap and rest (X, /usr/local, /var, and all)
150 meg = linux system, swap, and all.
40 meg = OS/2 HPFS os/2 (really need like 60 meg)

Something like this would do.  NetBSD maybe can fit in smaller on disk one.
Current has shared libs, and if anyone could get the time to make an interm
release ;-)
Your stuck with DOS on disk 1.

The NFS performance is limited by OS/2's tcpip version 1.2.1.
version 2.0 is MUCH faster, but still slower than I think it should
be for a 32 bit tcp/ip package.

NetBSD will almost alyways outperform Linux with NFS.  NFS by default
uses 8k packets that get fragmented.  On Linux, the networking code
does not support fragmented packets (major violation) so NFS has to 
generate 1.5K packets which produces more NFS packets and overhead.

235k/s is a good speed.  Many systems (like 26 processor sequent's,
486/33 NetBSD and 486/33 Linux) can not do much over 235k/s through
the filesystem.  Many systems like DOS can, because they are never 
reading more than one file at a time.
