NAME

eeprom − EEPROM display and load utility

SYNOPSIS

eeprom [−] [−i] [−f filename ] [field [ =value ]] ...

eeprom [−i] [−c] [−f filename ]

SYNOPSIS — SPARCstation 1 SYSTEMS

eeprom [ field [ value ] ]

AVAILABILITY

Not available for Sun-2 systems. 

DESCRIPTION

eeprom displays or changes the values of fields in the EEPROM.  It processes fields in the order given.  When processing a field accompanied by a value, eeprom makes the indicated alteration to the EEPROM; otherwise it displays the field’s value. When given no field specifiers, eeprom displays the values of all EEPROM fields.  The ‘−’ option specifies that fields and values are to be read from the standard input (one field or field=value per line). 

eeprom verifies the EEPROM checksums and complains if they are incorrect; if the −i flag is specified, erroneous checksums are ignored.  If the −c flag is specified, all incorrect checksums are recomputed and corrected in the EEPROM. 

DESCRIPTION — SPARCstation 1 SYSTEMS

eeprom displays or changes the value of fields in the EEPROM in the order given.  When given no field specifiers, eeprom displays the values of all EEPROM fields.  If a filed is specified, just that field is displayed.  If both a field and a value are specified, the field is set to that value, if possible.  Both the old and new values are displayed for the specified field. 

OPTIONS

−c Correct bad checksums. 

−i Ignore bad checksums. 

−f filename Use filename as the EEPROM device. 

− Read field names and values from the standard input.
