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 but is used for testing an optional
memory card. Memory module capacity is 2, 4, 8, or 16 MB.
After selecting subtest 05, the following message will appear:
Extended memory size (1:2 MB,2:4 MB,3:8 MB,4:16 MB) ?
Select the number corresponding to the installed memory card.
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 original data.
Constant data is 0000h, 5555h, AAAAh, and FFFFh.
Subtest 07 Cache memory
To test cache memory, a pass-through write-read comparison of '5A' data is
run repeatedly to a test area ('7000':'Program' size to '7000':='7FFF' (32 KB))
to check 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
