Diagnostic Test Types

The tests performed by the TokenDisk diskette Configuration and Diagnostic Program are divided into Group 1 and Group 2 tests.

A lobe cable must be connected from the selected adapter to a retiming concentrator or MAU for all tests.

Group 1 Diagnostics

Group 1 diagnostics test physical components, connectors, and circuitry of the adapter. They include the following tests:

■MMIO Register Write/Read Test

■Boot PROM Test (if the Boot PROM is enabled)

■AIP Checksum Test

■Shared RAM Boundary/Domain Test

■Shared RAM Write/Read Test

■Timer Test

■Open Adapter for Ring Operation Test

■Ring Operations Test

■Close Adapter Test

Each of these tests is explained in more detail below.

MMIO Register Write/Read Test

This test verifies that the PC can access the adapter’s memory mapped I/O registers correctly.

Boot PROM Test

This test verifies that the PC can access the Boot PROM correctly and verifies the integrity of the Boot PROM.
