3.5 MEMORY TEST
Subtest 01 RAM constant data (Execution time: 30 seconds)
This test writes constant data to Memory, and then
reads and compares them with the original data.
The constant data are "FFFFH", "AAAAH", "5555H",
"OlOlH" and "OOOOH".
Subtest 02 RAM address
seconds)
pattern data <Execution time: 10
This test makes the segment address and offset
address by XORing, and then writes the address
pat tern data and reads and compares them wi th the
original data.
Subtest 03 RAM refresh (Execution time: 20 seconds)
This test wr i tes constant data in 256 bytes length
to Memory, and then reads and compares it with the
original data. The constant data are "AAAAH" and
"5555H". A certain interval time will be taken
between the write and the read operations.
Subtest 04 Protected mode (Execution time: 78 seconds)
This test writes fixed data and address data to
memory (256 kbytes to MAX 640 kbytes or
1
Mbytes to
MAX. Mbytes ) in protect mode, and then reads and
compares it with the original data.
Subtest 05 Protected mode (3MB) (Execution time: 74 seconds)
This test writes fixed data and address data to
memory
(1
Mbytes to 4 Mbyts) in protect mode, and
then reads and compares it with the original data.
Subtest 06 LIM (Expansion memory) (Execution time: 84 seconds)
Run the same test as subtest 04 for the expansion
memory page' frame address (DO OOOH) and the block
select register (208H/2l8H) and memory size
(3
Mbytes
+
384 kbytes). This performed for every 64
kbytes.
