mode), the SCSI firmware is performance optimized for desktop applications. The firmware default condi- tion for the PM bit is set to one for Desktop mode. During the manufacturing process, the Saved value of the PM bit remains set to the firmware default condition (one) for drives with the LW interface. Drives man- ufactured with all other interfaces (LC) set the Saved value of the PM bit set to the Server mode (zero).

[3]When the Performance Mode bit (Page 0, Byte 2, Bit 7) is set to Server mode (zero), the Number of Cache Segments should be set to three (03h). When the Performance Mode bit (Page 0, Byte 2, Bit 7) is set to Desktop mode (one), the Number of Cache Segments should be set to sixteen (10h).
