only.
Figure 5-8 Memory Menu
The keys that follow are available in the Memory menu:
r — Returns to the Individual Diagnostics menu.
d — Runs a Dynamic RAM (DRAM) test, similar to the power-ON
DRAM test, but tests only the memory not in use by the boot
kernel.
f — Performs the power-ON Flash checksum.
F — Performs a read/write test on the application area of flash
memory, which overwrites the application software. Reload the
software after the test. Requires a data key (Spacelabs
Healthcare Field Service Engineers only).
g — Runs the power-ON GDS SRAM test. The SRAM stores the
trend data (GDS) for the patient.
n — Performs a checksum on NVRAM.
N — Requires a data key (Spacelabs Healthcare Field Service
Engineers only). Performs a read/write test of the NVRAM, which
overwrites configuration parameters in NVRAM. After the
NVRAM test completes, NVRAM must be zeroed with the data
key attached. The boot parameters and sysgen values must be
reentered.
