Description

Boot ROM Headers and Data

15 seconds

Verifies headers and data

Checksum

 

checksum for all firmware

 

 

volume regions throughout

 

 

the Boot ROM.

 

 

 

Verify BOF Flash with CRC

1 second

Verifies 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 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.

 

 

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.
