Normally during boot a basic test is run, but if you Stop-A into the PROM
itself you can manually run a more thorough memory test, although I forget
how (probably 'test memory' or similar depending on PROM version).
Although only the larger servers have a keyswitch, all systems (AFAIK) have
a 'diag-switch?' PROM variable which you can set to true to make the system
run more advanced tests automatically when booting.
