Yes, it's the PALcode that does all of the machine check/logout area stuff.

Depends... there are some generic machine check vectors. There are some
that are processor-specific (e.g. EV4, EV5, etc.). There are some that
are core logic chipset-specific (e.g. APECS, ALCOR, LCA, etc.). There
are still some others that are platform-specific (AlphaStation 400,

The only documentation I know of that exists for the logout area stuff is:
(1) PALcode source for each platform.
(2) Digital UNIX (formerly DEC OSF/1) source.
The Alpha architecture manual describes some of the generic logout area goo
(e.g. offsets to processor-specific stuff). The individual processor manuals
might have some info about the processor-specific things, but I'm not sure
If you are having problems w/ machine checks on an AlphaStation 400, Matt
and/or I can probably help you w/ the logout area stuff.
