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 8 MB, 16 MB, and 32
MB.
After selecting subtest 05, the following message will appear:
Extended memory size
(1:8 MB,2:16 MB,3:32 MB)?
Select the number that corresponds to the memory card installed in the com-
puter.
Subtest 06 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) for CPU cache memory. One
test takes 3 seconds.
Number of misses < Number of hits → OK
Number of misses ≥ Number of hits → Fail
