32 Appendix AXD Tools Test Reference

AXD EFI Tools Tests

These tests are available if your Xserve is running AXD EFI tools.

Startup Tests

These tests are automatically run when you start up AXD EFI tools.

SMBIOS tests check to see if bad memory was detected and mapped out at Xserve

startup. When the Xserve tests memory at start up, it automatically maps out bad

memory. Mac OS X doesn’t see this mapped out memory, so the non-SMBIOS memory

tests don’t test it. The SMBIOS test reports these mapped out DIMMS.

When an ECC error occurs, memory catches the problem and and fixes it. When you run

other memory tests, the tests don’t realize an error has occurred. The ECC tests detect

these memory fixes and report them.

Notes

Test Estimated completion time Description

SMBIOS Self-Test 1 second Checks the SMBIOS tables for 32-bit

errors (type 18) and 64-bit errors (type

33). Also verifies that the mapped-in

DIMM size is appropriate for the slot

it’s inserted into. If there’s a size

mismatch, an error occurs.

ECC Error Count 1 second Reports the number of ECC errors, and

then resets the count

Test Estimated completion time Description

Boot ROM Checksum 1 second Verifies the Boot ROM checksum

Boot ROM FW GUID MAC

Addr Checksum

1 second Verifies the Boot ROM FireWire GUID

MAC address checksum

Test Estimated completion time Description

MAC Address Verification 1 second Verifies MAC address isn’t all FFs or

00s

PCI-E 4 LinkWidth Verification 1 second Verifies PCI link width is 4
