DRAM Parity Checking

When enabled, turns on parity checking for the system RAM. This should be enabled if you are using parity checking (or ECC), and disabled otherwise. The default is normally "Disabled" since (unfortunately) most modern systems don't use parity memory. I recommend the use of parity memory; see here for details on what parity memory is, and see here for a discussion of the merits of parity memory versus non-parity memory.

Warning: If you turn on parity checking on a system that does not have parity memory in it, the system will halt with a parity error as soon as it tries to boot up. If you turn off parity checking on a system that does have parity memory, the system will run just fine, but you will have no parity checking protection active.
