Jumper settings
Jumpers may be fitted to select the following options:

Note: Some systems may require you to use the 15 head logical architecture. This is because they translate a drive greater than 4 GB by multiplying the head count by 16.  The result (16 x 16 = 256) is interpreted as 0 heads with a 0 capacity and is an illegal head count.  Selecting the 15 head logical jumpers produces a legal translation (16 x 15 = 240). The translated cylinder count varies to achieve the drive's full capacity.

Capacity clip to 2GB/32GB with logical head 16
This option can be used in situations where there is a BIOS limitation and the drive is not recognized.  The following jumper settings forces the values of Word 1, 3, 6 and 60-61 in Identify Device data as follows:
 
IC35L060AVER07, IC35L040AVER07 (factory default capacities > 32 GB)
Word 1/3/6 (C/H/S): Remain ship default value
Word 60/61 (LBA) 66055248

Note: Installing the 2GB/32GB capacity clip jumpers for a 34GB and higher drive reduces the drive capacity to 33.8GB.
 
IC35L030AVER07, IC35L020AVER07, IC35L010AVER07 (factory default capacities < 32 GB)
Word 1/3/6 (C/H/S) 4096/16/63
Word 60-61 (LBA) Remain ship default value

Note: Installing the 2GB/32GB capacity clip jumpers for a drive with a capacity of less than 34GB reduces the drive capacity to 2GB.

Disabling auto spin for logical head 16

These jumper settings are used for limiting power supply current when multiple drives are used.  The command to spin up is SET FEATURES (subcommand 07h).

Disable auto spin

Notes:
 
  1. 16 head logical architecture is enabled as the shipping default. Master is set to on (i.e. jumper on pins A-B and G-H). No other jumpers are fitted.
  2. Auto Spin Disable, disables the drive from automatically spinning up when power is applied.
  3. The clip capacity 2GB/32GB option clips the capacity of the disk drive down to 2 GB for drives with a capacity of less than 34GB and clips the capacity down to 33.8GB for drives with a capacity of more than 34GB. For example, a 10.1GB drive with this option set will appear as a 2GB drive and a 40GB drive with this option set will appear as a 33.8GB drive.
  4. When CABLE SELECT is specified, AT interface signal #28 CSEL  determines the drive address as follows:
  1. When CSEL is grounded or at a low level, the drive address is 0 (Device0).
  2. When CSEL is open or at a high level, the drive address is 1 (Device1).
