|
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 for configuring network speeds such as 1000 |
|
|
| Mbit/s. |
|

|
|
EEPROM | This test verifies the content of the electrically erasable programmable |
|
|
|
|
| |
| 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. |
|
|
|
|
|
|
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 | These tests verify that the NDIS driver is able to send packets to and |
|
|
Loopback PHY | receive packets from the adapter. |
|
|
|
|
|
|
Test LED | This test causes all of the port LEDs to blink 5 times for the purpose of |
|
|
| identifying the adapter. |
