CPU: i386DX (386-class CPU)
real memory = 2359296 (2304K bytes)
avail memory = 1204224 (1176K bytes)
:-)
Btw., the 2304 KB is a lie, 256 K of the ISA hole is being remapped.

The machine sort of works:
Enter pathname of shell or RETURN for sh:
# swapon -a
swapon: adding /dev/wd0s1b as swap device
# fsck
** /dev/rwd0a
** Last Mounted on /
** Root file system
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
CLEAN FLAG NOT SET IN SUPERBLOCK
FIX? [yn] y

...but every now and then, i get:
# pstat -T
panic: kmem_malloc: kmem_map too small
Just curious: is there any way to avoid this? I'm somewhat surprised,
since the kmem_map should suffice for 32 MB of VM, so how comes that
it's ``too small''?
(I could recompile elsewhere, but would like to use the machine for
some light-weight work.)
