Certainly a system implementation can provide the registers and CPU notification mechanism to allow this function. Sun did, but most PC manufacturers don't. The ones that do probably won't give out the information (Compaq, et al). The only way I know this might be possible with commonly available PC hardware would be if Intel included this sort of feature in their chipsets which provide an ECC function using parity memory SIMMs. Otherwise that function is embedded within the SIMM, right?
