Quantum ProDrive 210AT

The following values are used to set the PC/AT CMOS Table.

Cylinder	873
Heads		13
Sectors		36
Write Precomp	None or 65535*
Landing Zone	873

*= The Quantum ProDrive does not require Write Pre compensation, your CMOS setting should be set to reflect that this feature is not enabled. A value of 65535 is a number that many BIOS manufactures use to disable this feature if the value 'none' is not present.

Jumper Settings

The Prodrive has three drive mode jumper options; DS, SP and SS. To configure the drive as:

• The MASTER of a two drive configuration or as the only drive: Jumper DS only, SP and SS open.
• A SLAVE drive in a two drive configuration: Remove any jumpers across DS, SP or SS.
• A MASTER drive in a two drive configuration if the SLAVE drive does not use DASP: Jumper DS and SP only.
• SS not used, DO NOT install a jumper across this position.

The SP jumper is only used when the second drive in a two drive configuration does not support DASP. DASP (Drive active / drive 1 present) is a CAM (Common Access Method) defined signal that indicates the presence of a second drive, DASP is used during power on initialization and after a reset. Prior to this definition, products were introduced which did not utilize this method to detect the presence of a second drive. The SP jumper is only used on the MASTER drive, with the DS jumper, when the second drive does not support DASP.
