Probably a component of the memory exerciser. DEAD BEEF being a common
hexadecimal flag used for diagnostics.
I don't recall the exact commands, but it's something like:
I've had to run the Memory Exerciser with multiple subprocesses (like 4 or
8) to really thrash a suspect system and expose some memory problems with it.
The SRM has a pseudo filesystem on it, you can use 'ls' like:
>>> ls *exer*
>>> ls *diag*
Commands, scripts and I/O files appear here. You can 'cat' things, like:
>>> cat el
this displays the "Event Log" (el), a buffer file that will have all
the POST diagnostics, including some that are suppressed from normal
display as well as output from diagnostic processes.
There's cool things in the SRM, but the FORTH based OpenBootProm still
makes a better ROM monitor IMHO.
