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'.
