Troubleshooting 7-13
The test command also does a quick test on the system speaker. A beep is
emitted as the command starts to run.
The tests are run sequentially, and the status of each subsystem test is
displayed to the console terminal as the tests progress. If a particular device is
not available to test, a message is displayed. The test script does no destructive
testing; that is, it does not write to disk drives.
The syntax is:
test [argument]
Use the -lb (loopback) argument for console loopback tests.
To run a complete diagnostic test using the test command, the system
configuration must include:
• A serial loopback connected to the COM2 port (not included)
• A parallel loopback connected to the parallel port (not included)
• A trial diskette with files installed
• A trial CD-ROM with files installed
The test script tests devices in the following order:
1. Memory tests (one pass)
2. Read-only tests: DK* disks, DU* disks, DR* disks, DQ* disks, DF* disks,
MK* tapes, DV* floppy.
3. Console loopback tests if -lb argument is specified: COM2 serial port and
parallel port.
4. VGA console tests: These tests are run only if the console environment
variable is set to serial. The VGA console test displays rows of the word
compaq.
5. Network internal loopback tests for EW* networks.
NOTE: No write tests are performed on disk and tape drives. Media must be
installed to test the diskette drive and tape drives.
