• CPU MMX Shift: Tests the MXX commands PSLL and PSRL. If errors are detected, the
failed commands are listed.
• CPU MMX Data Transfer: Tests the MXX commands MOVD and MOVQ. If errors are
detected, the failed commands are listed.
• CPU MMX Misc.: Tests the MXX commands PCMPEQ, PCMPGT, PACKSS, PACKUS
and PUNPCK. If errors are detected, the failed commands are listed.
- HD Test
The HD Tests are used to perform a variety of Hard Drive checks, as described below.
For test procedure instructions, see the 7-6-1-1-4 "HD Test" on page 7-122 .
• Hard Drive Full Test (w/o Scan): Performs a battery of tests to examine the hard drive
and ensure that it can perform all its functions. All the remaining tests are performed on
the hard drive to ensure that the hard disk controller and the drive mechanism are working
correctly. The disk surface itself is also checked. This test may take 3.5 minutes.
• Hard Drive Linear Seek: Moves the hard disk drive heads from track 0 to the maximum
track one track at a time.
• Hard Drive Funnel Seek: Moves the hard disk drive heads in a funnel fashion (from the
first track to the last, then to the second track, the second last track, the third track and so
on).
• Hard Drive Surface Scan: Scans the surface for defects on the hard disk drive.
- Memory Test
The Memory Tests are used to perform a variety of memory checks, as described below.
For test procedure instructions, see the 7-6-1-1-5 "Memory Test" on page 7-124 .
• Full Memory Test: Uses 18 test patterns to test memory locations. If errors are detected,
the address of the block in which the error was detected is shown. During testing, these
diagnostics will also look for parity errors and other exceptions. If encountered, these are
added to the test log as errors.
• Memory Pattern Test: Uses several test patterns to test as much memory as possible.
• Memory Parity Test: Checks for parity errors on the memory bus during intensive string
transfer operation. If an error is detected, the address of the failed block is displayed.
- Video Test
The Video Tests are used to perform a variety of video diagnostic tests, as described below.
These tests use 18 test patterns to fill the video buffer, testing your graphics acceleration and
text output
For test procedure instructions, see the 7-6-1-1-6 "Video Test" on page 7-126 .
• Full Video Test: Test the system’s video capabilities. This involves testing the memory,
testing the graphics acceleration and testing the text output. You can follow the tests
being performed on the monitor. This test can be cancelled at any time by pressing <
Esc>
on the keyboard.
• Video Memory: Tests the video memory by filling the video buffer with 18 test patterns,
one pattern at a time. These tests fill the entire screen with a single color.
