NAME

       ns820-diag  - EEPROM setup and diagnostic program for ethernet cards based on the National
       Semiconductor DP83820 chip series.

SYNOPSIS

       ns820-diag [options]

DESCRIPTION

       ns820-diag is a program that you can use to diagnose problems with ethernet cards based on
       the National Semiconductor DP83820 chip series.

OPTIONS

       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.

       -# <cardnum>
              Use card number <cardnum>.

       -a, --show_all_registers
              Print all registers.

       -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 ns820-diag with the options
              '-t -1'.
