Section 7-2 - Diagnostics
•
CPU String Operations:
Tests the proper operation of the string commands LODS,
MOVS, SCAS and STOS with 8, 16 and 32 bit operands. If errors are detected, the failed
commands and operands are listed.
•
CPU Logical Operations:
Tests the proper operation of the logical operations AND,
NOT, OR and XOR with 16 and 32 bit operands. If errors are detected, the failed
operands are listed.
•
CPU Math Registers:
Tests the coprocessor register stack, pointers and commands
FLDLZ, FLDPI, FLDLN2, FLDLG2M FLDL2T FLDL2E and FLD1. If errors are detected,
the failed steps and commands are listed.
•
CPU Math Commands:
Tests the coprocessor commands FBLD/FBSTP, FLD/FST,
FXCH, FCOM, FICOM, FTST, FXAM and FUCOM. If errors are detected, the failed
instructions are listed.
•
CPU Transcendental:
Tests the coprocessor transcendental commands F2XM1,
FPATAN, FPTAN, FYL2XP1, FCOS, FSIN and FSINCOS. If errors are detected, the
failed commands are listed.
•
CPU MMX Arithmetic:
Tests the MXX commands PADD, PSUB, PMUL and PMADD. If
errors are detected, the failed commands are listed.
•
CPU MMX Logical:
Tests the MXX commands PAND, PANDN, POR and PXOR. If errors
are detected, the failed commands are listed.
•
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
.
•
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.
