5 Broadcom Advanced Control Suite 2 (BACS2) 171
E
Item Description
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
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.
Test LED This test causes all of the port LEDs to blink 5 times for the purpose of
identifying the adapter.
