Three tests are shown on the menu: a "quick” test, a “full” test and a
“continuous” test.
Test Selection
The “quick” teat checks a very small percent of the memory in each RAM chip in a
short time. The test will run in three seconds. Use this test to quickly find
major RAM failures. If RAM in bad In an area other than the few places the test
checks, a bad chip may be undetected by this test.
The “full” test exhaustively tests all 64K of each auxiliary bank available on
the card. The test runs approximately three seconds per 64k. Yogi should always
run the full test after adding or changing RAM on the card or when first
installing the card. The “full” test runs the “quick” test and then
exhaustively checks all banks found good by the “quick” test. Bad or incomplete
banks are not tested as they could not be used by any program.
The “continuous test runs the full test over and over until you press the
Escape key. Use the continuous test if a problem develops with the card after
it has been in use for awhile as many problems with RAM show up as intermittent
problems. Ogre run of the “full” test might not disclose such a problem whereas
its continued running would.
Running A Test
Running the “quick”, “full”, or “continuous” tests shows a high resolution
picture of the MultiRam C Card. Each RAM socket is shown exactly as mid oat on
the card.
