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, DR* disks, DQ* disks, MK* tapes, DV* floppy.
NOTE: You must install media to test disks, tapes, and the floppy drive. Since
no write tests are performed, it is safe to test disks and tapes that
contain data.
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.
