MEMORY TEST
Constant data
This subtest writes constant data to conventional memory (640KB), then
reads and compares it with the original data. The constant data is FFFFh,
AAAAh, 5555h, OlOlh, and OOOOh.
Random data
This subtest writes random data to conventional memory (640KB) , then reads
and compares it with the original data.
Sequential data
This subtest writes sequential data to conventional memory (640KB), then
reads and compares it with the original data repeatedly. The sequential data
is OOh to FFh.
Addresspack
This subtest packs the test address and writes data to conventional memory
(640KB), then reads and compare it with the original data.
Memory refresh
This subtest writes data to conventional memory (640KB), then reads and
compares it with the original data. The data is OOh, 55h, AAh, and FFh. There
is a delay between the write and the read operations.
Backup memory
This subtest writes data (FFh, AAh, 55h, and OOh) and address pattern data
created by XORing (Exclusive-ORing) high/low of the offset address to
memory (addressed FOOOOh to F07FFh), then reads and compares it with the
original data. Before and after the test data is preserved.
EMS mode
This subtest tests EMS memory (page frame address DOOOOh) and block
select register (03h) every 64KB in the same way as subtest 06.
