Jumpers; Master; Slave; Cable Select - IBM Deskstar 25GP Installation And Reference Manual

Jumpers

Master

If the IBM Deskstar is the only drive on the cable, or the Master drive on a two-drive
cable, set the jumpers for Master.

Slave

If the IBM Deskstar is the Slave drive on a two-drive cable, set the jumpers for Slave.

Cable Select

The 40 pin, 80 conductor ATA/IDE cable included with your drive is constructed using the
Cable Select configuration. If your motherboard or controller card supports Cable Select,
you can set the drive address jumper to Cable Select. Attach the drive to the black
connector for Master or the gray connector for Slave. Attach the blue connector to the
system ATA/IDE port on the motherboard or controller card.

Slave Present (Device 0 Forcing Device 1 Present )

If your Slave drive is an older drive that may not signal its presence on the bus, set the
jumpers on your Master drive to Slave Present.

2/32 GB Clip

For a DJNA model drive:
If your BIOS is incompatible with cylinder values higher than 4,096 cylinders, the 2/32 GB
clip jumper truncates the cylinder and LBA count of your drive to 4,096 cylinders (2 GB
capacity).
