Workstation 4 Diagnostics
Workstation 4 Diagnostics Utility
CPU Type
All current and future Workstation 4 system boards run the AMD Geode
SC3200. AMD purchased the National Semiconductor Corp. Geode
embedded processor line in 2003.
RAM Space Available
This field displays the amount of available RAM, located in the single
DIMM installed on the system board. The value displayed on your WS4
will not always agree with that shown in Figure 4-1. This because early
units shipped with a 64M DIMM, while the workstation currently ships
with a 128M DIMM. The change from 64M to 128M was not driven by
application software requirements, but memory price points. A 64M
DIMM is adequate to run all current application software.
CPLD Version
The CPLD (Complex Programmable Logic Device) is located on the WS4
System Board. Greater detail can be found in the system board technical
descriptions located in the WS4 Field Service Guide. The device contains a
microprocessor and firmware, therefore the CPLD Version field refers to
the firmware version running on that device.
The CPLD firmware can only be changed using a specialized parallel port
programmer attached to system board connector J16. The factory and
authorized repair centers have this capability.
Boot Loader Version
The Boot Loader is located on the WS4 system Board. Greater detail can
be found in the system board technical descriptions located in the WS4
Field Service Guide or in Chapter 1 of this manual.
The Boot Loader is a Flash EEPROM programmed at the factory. Page 4-3
details changes to the Boot Loader that affect how the WS4 behaves if a
POST error occurs. In January 2004, a change made to the Boot Loader
(Version 2.0.10 or later) provides support for a Sandisk (202 Series) 64M
CF Card.
After the WS4 leaves the factory, the boot loader can be updated in one of
two ways. One way is the DOC Utility, or DOCUTILITY.EXE, located in
the \DOC\Utilities folder. DOCUTILITY also supports a command line
mode that allows the CAL to upgrade the Boot Loader as part of an
application download or upgrade. In either case, the Docutility requires
that a binary file called LOADER.ROM is present on root of the CF card.
