201-XXX-Y99	1. Isolate the failing DIMM.
(Multiple DIMM failure, see error text)
		a. Replace a DIMM in bank with a known good DIMM.
		b. Rerun memory diagnostic for the failing bank.
		c. If test fails, mark replaced DIMM as good DIMM.
		d. If test passes, mark replaced DIMM as bad DIMM.
		e. If DIMM tested is bad, replace the bad DIMM.
		f. If DIMM tested is good, do not replace it.
	2. Repeat steps 1a through 1f with other DIMMs in the failing bank
		until the error is corrected.
	3. If error is not corrected, replace system board.
