Chapter 11: DOS Diagnostics

C3. DMA Test

Function: Both high and low priorities DMA are tested. It moves data from the host memory to NIC SRAM, verifies data, and then moves data back to the host memory again to verify data.

Default: Enabled

C4. MII Test

Function: The function is identical to A2. Control Register Test. The test writing zero and one into the test bits to insure the read only bits value are not changed, and read/write bits are changed accordingly.

Default: Test Enabled.

The test attempts to read the register configuration file ‘miireg.txt’ for the register defines. If the file does not exists, the following table is used. See Table 9.
