|
||||
*
|
||||
* 8/3/02 Enhanced and incorporated in lm_sensors 2.6.5
|
||||
* 13-December-2001 Arjan van de Ven <arjanv@redhat.com>
|
||||
* Fix memory bank type (DMI case 6)
|
||||

||||
* Fix return value in dmi_bus_name
|
||||
* Additional sensor fields decoded
|
||||
* Fix compilation warnings

|
||||
* 6-August-2002 Jean Delvare <khali@linux-fr.org>
|
||||
* Reposition file pointer after DMI table display
|
||||
* Disable first RSD PTR checksum (was not correct anyway)
|
||||
* Show actual DMI struct count and occupied size
|
||||
* Check for NULL after malloc
|
||||
* Use SEEK_* constants instead of numeric values
|
||||
* Code optimization (and warning fix) in DMI cases 10 and 14
|
||||
* Add else's to avoid unneeded cascaded if's in main loop
|
||||
* Code optimization in DMI information display
|
||||
* Fix all compilation warnings
|
||||
*
|
||||
* 9-August-2002 Jean Delvare <khali@linux-fr.org>
|
||||
* Better DMI struct count/size error display
|
||||
* More careful memory access in dmi_table
|
||||
* DMI case 13 (Language) decoded
|
||||
* C++ style comments removed
|
||||
* Commented out code removed
|
||||
* DMI 0.0 case handled
|
||||
* Fix return value in dmi_port_type and dmi_port_connector_type
