Subtest 05 Memory module
NOTE: To execute this subtest, an optional memory card must be
installed in the computer.
This subtest functions the same as Subtest 04, except it is used for testing an
optional memory card. Memory module capacity is 2, 4, 8, and 16 MB.
After selecting Subtest 05, the following message appears:
Extended memory size (1:2 MB,2:4 MB,3:8 MB,4:16 MB) ?
Select the number that corresponds to the memory card installed in the
computer.
Subtest 06 Backup memory
This subtest writes constant data to memory from address C8000h to CFFFFh,
then reads new data and compares the result with the original data.
The constant data is 0000h, 5555h, AAAAh, and FFFFh.
Subtest 08 Cache memory
To test the cache memory, a pass-through write-read comparison of '5A' data
is run repeatedly to the test area ('7000':'Program' size to '7000':=7FFF' (32
KB)) to check the hit-miss ratio (on/off status). One test takes 3 seconds.
Number of miss hit < Number of hit → OK
Number of miss hit ≥ Number of hit → Fail
