Appendix D FORTH Diagnostics D-7
For example:
D.1.6 module-info
This command reports back the system CPU information including: the
microprocessor name, its revision, the speed at which it is running in megahertz,
and the SBus speed in megahertz.
For example:
D.1.7 test-memory
All of the system main memory will be tested if the system
diag-switch?
parameter is
true
. If the
diag-switch?
parameter is
false
, this test uses the
selftest-#megs
parameter in NVRAM to determine how much memory to test.
The default for the
selftest-#megs
parameter is
1
, so only 1 megabyte of memory
is tested.
To change the default amount of memory tested using the
selftest-#megs
default
parameter, type this command:
This sets the desired memory size to be tested to 256 megabytes.
