User Guide
■ Name —Indicates the official name of the board, given by the Board Test System.
■ Part number —Indicates the part number of the board.
■ Serial number —Indicates the serial number of the board.
■ Factory test version —Indicates the version of the Board Test System currently
running on the board.
■ Factory test date —Indicates the release date of the Board Test System currently
running on the board.
■ MAX II ver —Indicates the version of MAX II code currently running on the board,
which resides in the \kits\stratixVGX_5sgxea7nf45_100g\examples
directory. Newer revisions of this code might be available on the
100G
Development Kit, Stratix V GX page of the Altera website.
■ MAC address —Indicates the MAC address of the board.
MAX II Registers
The MAX II registers control allow you to view and change the current MAX II
register values as described in
Table 6–1 . Changes to the register values with the GUI
take effect immediately. For example, writing a 0 to SRST resets the board.
■ SRST —Resets the system and reloads the FPGA with a design from flash memory
based on the other MAX II register values.

(PSR)
Read / Write
Determines which of the flash memory to use for FPGA
reconfiguration. The flash memory ships with pages 0 and 1
preconfigured.
Page Select Override
(PSO)
Read / Write
When set to 0, the value in PSR determines the page of
flash memory to use for FPGA reconfiguration. When set to
1, the value in PSS determines the page of flash memory to
use for FPGA reconfiguration.

(PSS)
Read only
Holds the current value of the illuminated USER_POF LEDs
(D32, D33, D34).
■ 0 = USER_POF1 LED (D34)
■ 1 = USER_POF2 LED (D33)
■ 2 = USER_POF3 LED (D32)
c This state selects a page not supported by the default
memory map. Use of this extra page may require the
flash to be re-imaged if you want to return to the
factory state.
