PRELIMINARY
7-2-4-4-1 PC Doctor
The PC Doctor Tests are divided into two main groups: Automatic and Interactive. The automatic tests
do not require user intervention. The procedure instructions for both groups are provided in 7-6-1-1 "PC
Doctor" on page 7-114.
•Automatic
- Full Back End Test without Hard Disk
This test performs a full system check without a Hard Disk scan. The test sequence includes
all automatic tests (excluding the Hard Disk. For test procedure instructions, see 7-6-1-1-1
"Full Back End Test w/o Hard Disk Scan" on page 7-114.
- Full PC Doctor Test (50 min)
The Full PC Doctor Test requires 50 mins (longer than the Full Test without Hard Drive). This
test performs a full system check as well as a Hard Disk scan. The test sequence includes all
automatic tests (including the Hard Disk).
For test procedure instructions, see 7-6-1-1-2 "Full PC Doctor Test (50 min)" on page 7-117.
-CPU Tests
The CPU Tests are used to perform a variety of CPU checks, as described below.
For test procedure instructions, see 7-6-1-1-3 "CPU Tests" on page 7-119
• CPU Full Test: Performs a battery of tests on the CPU to ensure that it is working
properly. All the remaining tests are performed as part of the CPU Test.
• CPU Registers: Tests the CPU Registers using the default test patterns. On 32 bit CPUs,
the extended registers are also checked. If errors are detected, the failed registers are
listed.
• CPU Arithmetics: Tests the proper function of the arithmetic commands ADC, ADD,
DEC, DIV, IDIV, IMUL, INC, MUL, SBB and SUB with 16 and 32 bit operands. If errors
are detected, the failed commands and operands are listed.
• 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.
