ETHERNET CONTROLLER EEPROM COMMANDS
This section describes the commands that provide access to the EEPROM for the Intel
82544EI Ethernet Controller.
initeth4rom
The initeth4rom command sets the 82544EI controller’s EEPROM to the default values.
These values include the ETH4 port Ethernet address, port settings, and ROM checksum.
Definition:
initeth4rom
filleth4rom
The filleth4rom command fills the first 64 words of the 82544EI controller’s EEPROM to the
value specified by fill_value (for test purposes only). For example:
filleth4rom ffff
puts 0xFFFF in the first 64 words.

ENVIRONMENT PARAMETER COMMANDS
The monitor uses on-board, non-volatile memory for the storage of environment parame-
ters. Environment parameters are stored as ASCII strings with the following format.
<Parameter Name>=<Parameter Value>
Some environment variables are used for board configuration and identification by the
monitor. The environment parameter commands deal with the reading and writing of
these parameters. Refer to Section for a list of monitor environment variables.
