D-8 SPARCstation 4/Xterminal 1 Service Manual • January 1995
When testing the installed memory alone, if
diag-switch?=false
, the
selftest-#megs
parameter takes a default value of 1 megabyte (factory-defined
value) or the value you set using
setenv
shown in the example above.
Any whole number may be used up to 256, and if the number exceeds the amount of
installed memory, all the installed memory in the system is tested. When the
test-
memory
diagnostic is running, the number of megabytes being tested is displayed
and counted down to zero during the test.
See the OpenBoot Command Reference for a detailed description and step-by-step
instructions for the available FORTH Diagnostic tests.
