SAF-TE Command Implementation
The Write Buffer command is also used to update the SAF-TE firmware
(stored in TWS Flash ROM). When used to upload firmware, the Write
Buffer command format appears as follows:
The Mode field is
0x
04 to indicate that SAF-TE firmware is being sent.
The Flag Byte can be one of the following values:
0x
00 - upload firmware
0x
FD - reset the LSI53C040 to run the new firmware
0x
FE - upload firmware complete; update Flash ROM tables to use
the new firmware
0x
FF - request status of firmware upload; returned using next SCSI
Request Sense command
