ns820-diag - EEPROM setup and diagnostic program for ethernet cards based on the National Semiconductor DP83820 chip series.
ns820-diag is a program that you can use to diagnose problems with ethernet cards
based on the National Semiconductor DP83820 chip series.
These programs follow the usual GNU command line syntax, with long
options starting with two dashes (`-').
A summary of options is included below.
Show summary of options.
Show version of program.
Be very unverbose.
Use card number <cardnum>.
Print all registers.
Dump EEPROM contents to stdout.
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.
Dump MII management registers.
Reset the transceiver.
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!
Try to identify the card, even if it is active.
-t, --chip-type <card>
Explicitly set the chip. To get all valid numbers, run ns820-diag with the options '-t -1'.
