I got NetBSD 1.6.something to work on a 386sx with 4MB ( maybe it were 6MB =
) a while ago. Didn't use the installer - made up a cut-down installation a=
nd a custom kernel on another x86 NetBSD box ( with plenty of memory and an=
 Athlon ) and transferred the whole thing on about 20 floppies because ther=
e was no network, no PCMCIA, no usable RS232 ( only these horrible 16540 wi=
thout buffers that can do 9600bps but no more ). After this chore it worked=
 pretty well for a 20MHz box without FPU ( didn't get around to build an FP=
U-less userland )

So - yes, 2MB is barely enough for the kernel alone. To install on a box wi=
th serious impediments ( slow, small memory, no network and such ) I'd reco=
mment putting the disk into another box and prepare it from there ( a USB-t=
o-IDE converter can be very useful for stuff like this - just used one to p=
repare a new disk for my SPARCbook on an Ultra 10. Not that the SPARCbook h=
as any of these impediments ( well, it's not fast anymore... ) but it still=
 saved me some OBP fiddling, setting up a netboot environment and the U10 i=
s definitely faster unpacking tgz files )

have fun
Michael
