I don't, to be honest. There is some code in /usr/src/sys/i386/isa/nmi.c= =20 that tries to detect the cause of an NMI, although I don't remember ever=20 seeing the messages when a parity error was detected. I guess it's=20 possible that (to some chipset vendor at least) 0x20 and 0x30 indicate=20 parity error, but neither our code or Linux's (see=20 http://fxr.watson.org/fxr/source/arch/i386/kernel/traps.c?v=3Dlinux-2.6#L74= 3 ) know those codes to mean parity error.
