Fujitsu 3000 Series Jumper Settings


19980406: Fujitsu 3000 Series Jumper Settings

Tech Note #6

Technicians should be careful when installing the new Fujitsu 3000 series Enhanced IDE hard drives. These will have model numbers MPA3xxxAT and MPB3xxxAT. These drives ship with default jumper settings which will not work in any division systems. The default setting is "cable select" and this setting does not work unless you have a special drive cable, and we don't.

You must therefore set the drive correctly for master or slave. Please note also that while Fujitsu does not distinguish between "master" and "master with slave present", there are two different settings for master and two different settings for slave. The reason for this is that older BIOSes do not recognize drives greater than 2 GB. In order to use these drives with an older BIOS, you must use the legacy jumper settings, which will set the drive type to 2 GB.

With the hard drive upside down (ie. circuit board up) the drive selection pins are numbered as follows:
2 4 6
1 3 5

The drive comes with 2-4 and 3-5 jumpered. This is the "cable select" mode. Do not use this setting!

On boards with new BIOSes, which recognize drives larger than 2 GB, use these settings:
Master: 1-2 and 3-5 jumpered.
Slave: 3-5 jumpered.

On boards with older BIOSes, use these settings:
Master: 1-2 and 5-6 jumpered.
Slave: 5-6 jumpered.

This information, including diagrams, is available on the instruction sheet packaged with the hard drive, or from Fujitsu's web site.
