That `window' is usually a SPARC register window, `window underflow'
is when someone tries to access a register window which isn't
Most likely to cause this problem is a mix of memory modules, eg you
have a bank which has both 4 MB and 1 MB simms, it might also be a fault
cache memory on the motherboard.
However if you know that the simms are placed correctly it might be an
issue with the graphics card, try to do a
boot cdrom - install w
this will bring up an interactive installer, but bypass OpenWindows.
(Same as you will see if you boot it without a keyboard)
