AIP Checksum Test

This test verifies that the adapter's node ID, channel identifier,
and supported function identifiers such as data rate, shared
RAM, and transmit buffer size are correct.

Shared RAM Boundary/Domain Test

This test verifies that the shared RAM base address is aligned
on the proper address boundary according to the shared
RAM page size setting and verifies that its domain does not
conflict with that of the adapter ROM.

Shared RAM Write/Read Test

This test verifies that the PC can correctly access the total
64 KB of available shared RAM.

Timer Test

This test verifies the adapter's timer operation by comparing
the adapter timing to the PC's timing.

Open Adapter for Ring Operation Test

This test prepares the adapter for an adapter ring operation
test. This test verifies the adapter's ability to transmit data
over the network. This test requires the adapter to be
connected to an STP or a UTP media cable with a DAU, MAU,
or CAU at the other end.

Ring Operations Test

This test assesses communication on the ring. The adapter
must be attached to the ring in order for this test to be
successful. The adapter also must be set to the correct ring
speed.

Close Adapter Test

This test verifies the adapter's ability to close the adapter and
terminate the Ring Operations Test. The adapter must have
been previously opened.
