  I'm trying to get a 486/33 machine up and running to do some network
testing with. Using either 1.2[.0] or Perry's SSTO disk (both his 1.2C
build and my 1.2D serial console build) I get a ffs panic:

  {here I try to track down which command exactly causes it to die}

# tar --one-file-system -cf - . | (cd /mnt ; tar --unlink -xpf - )
mode = 020640, inum = 2240, fs = /mnt
panic: ffs_valloc: dup alloc
syncing disks... 11 11 8 2 done

  It is *always* inode 2240. 
  After a reboot, the disklabel is gone. (Perry, did I mention to you
that the disklabel operation on the SSTO needs a -r?)
  
  I think: bad IDE drive. Try BIOS surface analysis. That comes up
clean. (Should I trust that?) 
  So, maybe this is bad ram, and the ram is always getting used for
buffer cache or something.

  {An aside: I seem to now have 5 NE2000 clones which fail their
onboard ram test. I had a sixth as well, which I stole from my wife's
286 terminal, and it failed to test out in this same machine using the
config utilities. I didn't try the other machine that I was setting
up, since it seemed to work and I didn't want to disturb it. I put the
card *BACK* into the 286 and it still works. Maybe this system is just
screwed up in general. I can't believe that I zapped all five of these
cards!!! Some don't probe at all with the config utility} 

  My current plan is to mope for awhile.
  Then I might pick up a new motherboard after reseating this one's ram.
