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.
