Operating instructions

The test command tests the entire system, a subsystem, or a specified device. If
no device or subsystem is specified, the entire system is tested.
To run a complete diagnostic test using the test command, the system configu-
ration must include a CD ROM and loopback connectors on COM2 and the par-
allel port.
The command syntax is:
t[est][-write][-nowrite"list"][-omit "list"][-t time][-q][dev_arg]
-write
Specifies that data will be written to the specified device
-nowrite
Specifies that data will not be written to the device specified in
the "list"
-lb
Specifies loopback testing
-omit
Specifies that the devices in the "list" are not to be tested
-t
Specifies the amount of time the test command is to run
-q
Defines data size as a quadword (64 bits). All values default to 8
bytes.
<dev_arg> Specifies the target device, group of devices, or subsystem to test
For example:
P00>>> t pci0 -t 60
In this example, the test command tests all devices associated with the PCI0
subsystem. Test run time is 60 seconds. When a subsystem or device is speci-
fied, tests are executed on the associated modules first, then the appropriate
exercisers are run.
