natsemi-diag [options]


netsemi-diag is a program that you can use to diagnose problems with ethernet cards based on the National Semiconductor DP83810 / 83815 chips.


These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

-h, --help

Show summary of options.

-V, --version

Show version of program.

-v, --verbose

Verbose mode.

-q, --quiet

Be very unverbose.

-a, --show_all_registers

Print all registers.

-# <cardnum>

Use card number <cardnum>.

-e, --show-eeprom

Dump EEPROM contents to stdout.

-E, --emergency-rewrite

Re-write a corrupted EEPROM.

-p, --port-base <port>

Specify port to use.

-A, --Advertise <mediaype>

Advertise media type. Valid Options are: 10baseT, 100baseT4, 100baseTx, 100baseTx-FD, 100baseTx-HD, 10baseT-FD and 10baseHD.

-F, --new-interface <interface>

Interface number. Options that make sense are: 10baseT, 10base2, AUI, 100baseTx, 10baseT-FDX, 100baseTx-FDX, 100baseT4, 100baseFx, 100baseFx-FDX, MII and Autosense.

-H, --new-hwaddress <address>

Set card to a new hardware address.

-m, --show-mii

Dump MII management registers.

-R, --reset

Reset the transceiver.

-T, --test

Do register and SRAM test.

-w, --write-EEPROM <values>

Write to the EEPROMS with the specified values. Do not use this, if you do not know what you do!

-f, --force-detection

Try to identify the card, even if it is active.

-t, --chip-type <card>

Explicitly set the chip. To get all valid numbers, run natsemi-diag with the options '-t -1'.
