Hello,
maybe you have also a dump for a 4000-100A ?
I have a motherboard which seems to have problems to Bcache or Pcache, and
another one which I took as replacement, which has a very old version.
I wonder if there's a way to dump the firmware in some way from the
non-working one, then update the other...
Of course I would avoid to desolder and resolder the flash Roms...
Andrea
