4.5 Memory Test
Subtest 01
RAM constant data
This subtest writes constant data to conventional memory (0 to 640KB), then reads
and compares it with the original data.
The constant data is FFFFh, AAAAh, 5555h, 0101h, and 0000h.
Subtest 02
RAM address pattern data
This subtest writes address pattern data created by eXclusive-ORing (XORing) the
address segment and address offset to conventional memory (0 to 640KB), then reads
and compares it with the original data.
Subtest 03
RAM refresh (real mode)
This subtest writes 256-byte units of constant data to conventional memory (0 to
640KB), then reads and compares it with the original data.
The constant data is AAAAh and 5555h.
There is a delay between the write and the read operations.
Subtest 04
Protected mode
This subtest writes constant data and address data to extended memory (addressed
100000h to the max.), then reads and compares it with the original data.
The constant data is FFh, AAh, 55h, and 00h.
Subtest 05
Memory module
NOTE:
To execute the this subtest, an optional memory card must be installed in the
T2200SX.
This subtest is the same as Subtest 04; it is used for testing an optional memory card.
Memory module capacity is 2MB, 4MB, and 8MB.
After selecting Subtest 05, the following message will be displayed.
Extended memory size (1:1MB,2:2MB,3:4MB,4:8MB) ?
Select the number that corresponds to the memory card installed in the T2200SX.
