Things You Should Know the First Time You Power On Your Machine
3.7.2 Effects of Window NT Serviceability support on the update process
One of the most important changes, resulting from the implementation of
Windows NT serviceability support, is the relocation of the AlphaBIOS to a
different sector in flash ROM. This relocation was required to accomodate
the space requirements for fatal error logging. All update methods, from
a system running firmware prior to V5.3, with the exception of a BOOT
command update of the 5.3 or later image, will require the update process
to be executed twice. The first time to update the SRM firmware and the
second time to update the AlphaBIOS firmware. Failure to execute the
process twice will leave the AlphaBIOS as an invalid image and prevent
access to AlphaBIOS. View the information in Chapter 2 for update
changes.
3.7.3 EEPROM commands for Windows NT error logging
The SRM V5.3 or later firmware uses a sector of flash (designated as an
eeprom error logging area) for the support of Windows NT fatal error
logging. Space for two halt error logs per CPU has been allocated. SRM
eeprom commands have been included to initialize the logging area and to
allow viewing of halt error log information. The error log viewing feature
is a supplement to the Windows NT support.
3.7.3.1 Build eeprom
A new SRM command, build -eeprom, has been implemented to initialize
and setup the eeprom error logging area. Initialization and setup of the
eeprom logging area will be required after an update of firmware has been
performed.
The following example shows the build -eeprom command.

3.7.3.2 Show eeprom
This example shows the eeprom halt area information displayed via the
show eeprom halt command. No errors have been logged.
P00>>>show eeprom halt

3.7.3.3 Clear eeprom
The clear eeprom halt command is used to clear the eeprom halt logging
area.
