Fujitsu BX620, PG-FCS103, PG-FCS102 manual Control Registers, Identifying the adapter

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	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.	E
