Touching the m key in the Individual Diagnostic menu displays the Memory menu.
Figure 5-6: Memory menu
The following keys are available in this menu:
r — Returns to the Individual Diagnostics menu.
d — Runs a DRAM test, which is similar to the power-ON DRAM test, but it tests only the
memory not in use by the boot kernel.
f — Performs the power-ON flash checksum to verify system software.
F — Performs a read/write test on the application area of flash memory. Since this overwrites
the application software, it has to be reloaded after the test. This requires a data key (Spacelabs
personnel must be present).
g — Runs the power-ON GDS SRAM test.
n — Does a checksum on the NVRAM.
N — Performs a read/write test of the NVRAM. Since this overwrites configuration parameters
in the NVRAM, after the test the NVRAM should be zeroed and the boot parameters and
sysgen values should be re-entered. This requires a data key (Spacelabs personnel must be
present).
