Memory Test
To execute the Memory Test, type 2 from the DIAGNOSTIC TEST MENU, press
Enter
, and
follow the directions displayed on the screen. Type the number corresponding to the subtest you
want to execute and press
Enter
.
Subtest 01
RAM Constant Data
This subtest writes constant data FFFFh, AAAAh, 5555h, 0101h, and 0000h to conven-
tional memory (0 to 640KB). The constant data is then read from conventional
memory and compared to the original data.
Subtest 02
RAM Address Pattern Data
This subtest writes address pattern data created by the eXclusive-ORing (XORing), to
the address segment and address offset in conventional memory (0 to 640KB). The
address pattern data is then read from conventional memory and compared to the
original data.
Subtest 03
RAM Refresh (Real Mode)
This subtest writes a 256-byte unit of constant data (AAAAh and 5555h) to conven-
tional memory (0 to 640KB). This data is then read from conventional memory and
compared to the original data.
NOTE: The size of the data being read and written to conventional memory causes a short
delay between the write and read operations.
Subtest 04
Protected Mode
This subtest writes constant data FFh, AAh, 55h, 00h and address data to extended
memory (addressed 100000h to the maximum address). The data is then read from
extended memory and compared to the original data.
