DS CS PK Rsvd
X= PK is a Parking position. The presence or absence of this jumper has no effect on the drive. Labeling may
indicate to place this jumper when configuring as a slave. This is to provide for retention of the jumper in the
event that it is needed later.
*Note: Cable Select (CS) utilizes a special cable configuration where the drive setting (Master or Slave) is
determined by its position on the 40-pin ATA cable. In this type of configuration both drives will have their
jumper set to CS. Cable Select is utilized on some OEM systems and is typically required for systems utilizing
Ultra ATA/66. For Ultra ATA/66 compliant cables, the master drive is placed on the outside (end) cable
connector and the slave drive is placed
on the intermediate cable connector.

Jumper Locations
The Maxtor® Fireball™ Plus KX disk drive has only one location where user configurable jumpers are found. The
jumper block is incorporated into the ATA / IDE cable connector. Using the jumper pins you can establish the drive
Master/Slave configuration.
The Maxtor Fireball Plu KX was developed by Quantum Corporation prior to its merger with Maxtor.
BIOS Settings
The following BIOS parameters are provided for customers needing to manually configure the Fireball Plus KX disk
drive. Both base 2 and base 10 capacity values are displayed.
Logical Cylinders 14,164 16,383 * 16,383 * 16,383 * 16,383 *
Logical Heads 15 16 16 16 16
Logical Sectors/Track 63 63 63 63 16
Total Logical Sectors 13,385,856 20,077,014 26,771,672 40,160,988 53,550,304
Base 10 Capacity 6,853 MB 10,279 MB 13,707 MB 20,562 MB 27,417 MB
Base 2 Capacity 6,535 MB 9,803 MB 13,072 MB 19,609 MB 26,147 MB
6.8 GB 10.2 GB 13.6 GB 20.5 GB 27.3 GB
*Note: Default Logical Cylinder value is limited to 16,383 as per the ATA-4 specification. Capacity may be
restricted to 8.4GB (or less) due to system BIOS limitations. Drives greater than 8.4GB in capacity require LBA
support. Check with your system manufacturer to determine if your BIOS supports LBA mode for ATA hard drives
greater than 8.4GB.

Special Considerations
Hard drives greater than 2.1GB may need to be divided into multiple partitions / logical drives. MS-DOS versions
4.0 through 6.22 allow a maximum primary partition / logical drive size of 2.1GB and are limited to 8.4GB in
physical drive capacity. The file systems supported by Windows 95, Windows 98 and Windows NT are not restricted
to the 8.4GB physical drive limit, but LBA support in the system BIOS is required.
Hard drives greater than 8.4GB in capacity may be restricted to 8.4GB (or less) due to system BIOS limitations,
operating system limitations, or both. Check with your system manufacturer to determine if your BIOS supports
the correct LBA extensions for hard drives greater than 8.4GB.
In order to achieve the Ultra ATA/66 transfer speed, you must have a system and BIOS that will support Ultra
ATA/66. The correct drivers must be loaded, and an Ultra ATA specific data cable must be used. The Ultra ATA
cables use the Cable Select (CS) method rather than a master/slave scheme, so the drive must be jumpered to
enable Cable Select.
