Appendix Server Diagnostics Test Reference 39
Test Estimated completion time Description
Boot ROM Headers and Data
Checksum
15 seconds Veries headers and data
checksum for all rmware
volume regions throughout
the Boot ROM.
Verify BOF Flash with CRC 1 second Veries that the low and high
limits for testing sensors are
correctly set.
SMBIOS Self-Test 1 second Checks the SMBIOS tables for
32-bit errors (type 18) and 64-
bit errors (type 33). Also veries
that the mapped-in DIMM size
is appropriate for the slot it’s
inserted into. If there’s a size
mismatch, an error occurs.
When the server tests memory
at startup, it maps out bad
memory. This mapped-out
memory is hidden from the
system and diagnostics so the
non-SMBIOS memory tests don’t
test it. The SMBIOS test reports
these mapped-out DIMMS.
