Interrupt Test The interrupt test checks the ability of the hardware to create an interrupt and the ability of
the driver to process the interrupt by forcing the generation of a predetermined number of interrupts. The
test succeeds if the device generates the interrupts and the driver processes all interrupts expected.
Loopback Test The loopback test is a diagnostic tool that routes transmit data through a loopback
connector back to the same adapter.
Link Test The link test inspects the link status (up or down) by checking the physical communication
channel between the host and the firmware.
Windows Diagnostic Test Messages
If a test fails, an appropriate error code is generated and displayed, as shown in Table 17. Note that this
table does not list error messages for the interrupt and link tests.
