7. In the error message window that warns of the network connection
being temporarily interrupted, click Yes . The diagnostic tests run
continuously and the Status field for each test displays the
accumulated total of passes and failures.
8. To stop the continuous testing, click Abort .
Control Registers
This test verifies the read and write capabilities of the network adapter
registers by writing various values to the registers and verifying the results.
The adapter driver uses these registers to perform network functions such
as sending and receiving information. A test failure indicates that the
adapter may not be working properly.
MII Registers
This test verifies the read and write capabilities of the registers of the
physical layer (PHY). The physical layer is used to control the electrical
signals on the wire and to configure network speeds such as 1000 Mbit/s.
EEPROM
This test verifies the content of the electrically erasable programmable
read-only memory (EEPROM) by reading a portion of the EEPROM and
computing the checksum. The test fails if the computed checksum is
different from the checksum stored in the EEPROM. An EEPROM image
upgrade does not require a code change for this test.
Internal Memory
This test verifies that the internal memory of the adapter is functioning
properly. The test writes patterned values to the memory and reads back
the results. The test fails if an erroneous value is read back. The adapter
cannot function if its internal memory is not functioning properly.
On-Chip CPU
This test verifies the operation of the internal CPUs in the adapter.
Interrupt
This test verifies that the Network Device Driver Interface Specification
(NDIS) driver is able to receive interrupts from the adapter.
Loopback MAC and Loopback PHY
These tests verify that the NDIS driver is able to send packets to and
receive packets from the adapter.
