Tests (T 4)
This is the cache system self-test.
The following tests are included:
DATA Store test
Tests the data store in the Model 90 primary cache. A
two-pass memory test is performed on the data store. This
test performs a read/compare/complement/write in both the
forward and reverse directions. The data store is accessed
through the IPR address space.
TAG Store test
Tests the tag store in the Model 90 primary cache. A two-
pass memory test is performed on the tag store. This test
performs a read/compare/complement/write in both the
forward and reverse directions. The tag store is accessed
through the IPR address space.
Memory
Self-Test (T 5)
This self-test is for the memory.
Setup Notes
If memory modules are not configured correctly, the memory test
fails, and the memory modules are not configured. Memory
modules must be installed in sets of 4, with the first set of
memory modules in slots 0A, 0B, 0C and 0D, and the second set
of memory modules in slots 1E, 1F, 1G and 1H. Refer to Chapter
6 for further information on memory module configuration.
