_ DEC-O-LOG for KN16-AA _ DOL, KN16-AA-F001 JUN 94 APPLICABILITY: This FCO is customer installable and it should be installed by Customer Services ONLY when demanded by the customer. This FCO is for all DEC3000/* Alpha AXP Workstations shipped beginning December 1992 until November 1, 1993, plus all DEC 3000 Model 600 and 600S systems shipped before February 16, 1994. PROBLEM & SYMPTOM: There is an EXTREMELY REMOTE possibility that in a below normal temperature environment, a SCSI controller transaction error could occur. Through extensive testing below normal operating temperatures, all observed occurrences of this condition have resulted in a detected illegal command. Because this condition in THEORY could cause data corruption we have supplied a MUP which will fix this condition. SOLUTION: Installation of this MUP will provide enhanced parity protection on SCSI controller transactions by programming parity pass through instead of parity generation in the SCSI controller chip(s).

It is for the DEC3000 Models 300, 300L, 300X, and 300LX systems with one or more 32 megabit Samsung SIMMs (Samsung part # KMM5368100-7) installed. Systems affected directly are those shipped to Europe. Other systems may exhibit this problem when a memory upgrade is installed. PROBLEM & SYMPTOM: These problems can range from systems not being able to boot OSF, to systems crashing, and will only show up on systems with one or more 32meg Samsung SIMM. SOLUTION: Install the EQ kit which is designed to solve system problems described above when the system contains 32Megabit Samsung SIMMs (part # KMM5368100). QUICK CHECK: Check for SAMSUNG 32megabit memory SIMMs and verify the system board is below revision K01. TOOL/TEST EQUIPMENT: Power-up self-test is all that is needed. FCO KIT ORDERING: .
