PC Server 320/520 - Traps after cache upgrade
Applicable to: World-Wide
Symptom
PCI/EISA versions of the IBM PC Server 320 and 520 hang or reboot while booting or loading an operating system. These errors have been seen with OS/2, Windows NT, and SCO/UNIX.
Problem Isolation Aids
- The system is an 8640 or 8641 PCI/EISA model.
- A 256KB L2 cache upgrade (Option P/N 94G3141) was installed.
- The system may have a second processor installed.
- Symptoms disappear when disabling cache in BIOS with <F2>.
- Diagnostics run without error.
Fix
1. Verify that the cache modules are installed correctly and that no pins are bent.
2. Verify the system board cache jumpers: 256KB cache: W5 and W10 should have pins 1 and 2 jumpered. 512KB cache: W5 and W10 should have pins 2 and 3 jumpered.
3. Replace any cache modules that have the word "Alliance" or the number AS7C3256-15PC with FRU P/N06H8510.
