HEX - Help Extended
The HEX command goes into an interactive, continuous mode of the HE
command.
The prompt displayed for HEX is the question mark (?). You may then
type the name of a directory or command. You must type QUIT to exit.
Example:
PPC x -Diag>HEX
Extended Help, Type <QUIT> to Exit
? lc
LC Loop Continuous Mode
? ISABRDGE irq
ISABRDGE ISA Bridge Tests (DIR)
IRQ Interrupt Request
? quit
PPC
x -Diag>
LA - Loop Always Mode
To repeat a test or series of tests endlessly, enter the prefix LA. The LA
command modifies the way that a failed test is endlessly repeated.
The LA command has no effect until a test failure occurs, at which time,
if the LA command has been previously encountered in the user command
line, the failed test is endlessly repeated. To break the loop, press the
BREAK key on the diagnostic video display terminal.
Certain tests disable the BREAK key interrupt, so it may become
necessary to press the abort or reset switches on the PowerPC board front
panel.
Example:
PPC x -Diag>la;ram adr
RAM ADR: Addressability............. Running ---> PASSED
(no errors detected so LA is ignored)
PPC x -Diag>
