In ASF Mode

1

, the Ethernet controller's ASF function reads the ASF CRC word to determine if the 

EEPROM is valid. If the CRC is not valid, the ASF Configuration registers retain their default 

value. This CRC does not affect any of the remaining Ethernet controller's configuration, including 

the Management Control Register.

The EEUPDATE utility meets the two basic requirements for an in-circuit programming utility. 

First, the utility can be used to update EEPROM images as part of an end-of-line production tool. 

Secondly, it can be used as a standalone development tool. The tool uses the two basic data files 
outlined in the following section (static data file and IA address file). To obtain a copy of this 

program, contact your Intel representative.

The EEUPDATE utility is flexible and can be used to update the entire EEPROM image or update 

only the IA address of the Ethernet controller.

The DOS command format is a follows:

 Parameter_1 Parameter_2

 

where:

Parameter_1 = filename or /D

Parameter_2 = filename or /A

Parameter 1

, above, is file1.eep, which contains the complete EEPROM image in a 

specific format that is used to update the complete EEPROM. All comments in the .eep file must 
be preceded by a semicolon (;).

Parameter 1

 can also be a switch /D. the switch /D implies: do not update the complete 

EEPROM image.

Parameter 2

, above, is file2.dat, which contains a list of IA addresses. the EEUPDATE 

utility picks up the first unused address from this file and uses it to update the EEPROM. An 

address is marked as used by following the address with a date stamp. When the utility uses a 

specific address, it updates that address as used in a log file called eelog.dat. This file should then 
be used as the .dat file for the next update. 

Note: Refer to the appropriate Ethernet controller’s EEPROM map and programming information for 

sample EEPROM images.

The 82544GC/EI and 82541ER do not support ASF.
