Audio

Level: 2. This test checks the SoundBlaster compatible audio sound system. The DSP chip, DMA Channel, and Interrupt Lines are checked for proper operation. An audible sound test completes the test; a bong sound alternating between left and right speakers should be heard.

Display

Levels: 1,2,3. This test checks multiple display subsystems. When manual testing is done, the

display pixels are first tested with 7 operator-paced test patterns: one each for white, red, green, blue, and black; then a vertical stripe pattern followed by a random display pattern. Press Enter or Contrast Up to pass, Esc or Contrast Down to fail, until the automated test begins. The automated display test first tests video memory by flipping to all video modes supported while writing / reading the video buffer with the 18 test patterns. Lastly, the VGA controller registers and VGA color-DAC registers are tested for proper operation.

Docked device

Levels: 1,2. The dock port can be left unconnected, connected to a SCSI tower via SCSI cable or connected to a dock. The level 1 test simply reports what is connected. If a specific device has been specified with the <Alt+D> command, then the test will report an error if anything other than that which what was specified is found. If a dock is connected and level 2 is selected, then the dock LED’s and latch are tested by blinking the selected LED and locking/unlocking. Respond ‘Y’ or ‘N’ as prompted to pass or fail each test depending on the observed performance.

SCSI CD ROM

Levels: 1,2. This test checks a SCSI CD ROM using the MSCDEX API. Instead of a clean boot, drivers must be loaded in CONFIG.SYS and AUTOEXEC.BAT. The following are a minimum driver set to enable SCSI CD’s as well as SCSI hard disks. Note: the directories listed below are the default.

CONFIG.SYS: devicehigh=c:\scsi\aspi8xx.sys /v devicehigh=c:\scsi\symcd.sys /d:aspicd0 devicehigh=c:\scsi\symdisk.sys

AUTOEXEC.BAT:

c:\windows\command\mscdex /d:aspicd0 /m:12 /l:H

The level 1 test does a quick random scan of the CD. The level 2 test does a linear scan, random scan, and a funnel scan of the CD to test for proper operation.

SCSI Hard disk

Levels: 1,2,3. This test operates similarly to the hard disk test. If multiple SCSI hard disks are present, only the first disk is tested. Load the SCSI hard disk drivers in CONFIG.SYS and AUTOEXEC.BAT before running this test.

Dock slots

This test is unimplemented at this time.
