:DIAGnostic:MEMory
NOTE
. This command overwrites everything saved in the NVRAM. The NVRAM
is reset to factory defaults.
Runs a combination of the EPROM test and the RAM test. This
command initializes the NVRAM. The EPROM test allows you to
run the EPROM checksum test to verify that the EPROM contents
are intact. The RAM test allows the user to run the RAM test to
verify that the processor RAM and the RAMs in the audio and video
generators are functional. The response will be any two of several
possible messages:
EPROM TEST PASSED
EPROM TEST FAILED
TEST PASSED
AUDIO RAM FAILED
BARS RAM FAILED
EMBEDDED RAM FAILED
TEST RAM FAILED
This command does not return a command prompt. Press ENTER
after tests are complete.
