Attention: Read First - IBM ATA-100 (EIDE) Hard Disk Drive User's Guide Supplement
If you are using Microsoft
instead, read the "Installing DiskGo!" section in the User's Guide. DiskGo! Will provide direction in setting jumpers.
If you are using Microsoft Windows NT
(Me) or IBM
OS/2
: Read this entire section on setting jumpers; this information supplements the information in your User's Guide.
Your new IBM ATA-100 (EIDE) Hard Disk Drive offers a choice of jumper configurations so that the drive will function properly on
the widest range of computers. In some older computers, the BIOS (basic input/output system) microcode will not recognize a large
capacity hard disk drive. Computers made before 1998 commonly do not recognize drives larger than 4.2 GB (GB equals
approximately 1 000 000 000 bytes). Many newer computers do not recognize drives larger than 8.4 GB or 32 GB. The following
instructions will help you determine if your computer has one of these BIOS limitations and the configuration settings your computer
requires so that the drive will be recognized.
IBM uses drives from a number of manufacturers. Locate the label on your hard disk and find the diagram that it corresponds to from
the following figures. (The sample model numbers given are for 20.4 GB drives). Configure your drive using a jumper setting from
Set A in the figure that corresponds to your drive. Return to the User's Guide and follow instructions beginning with "Determining
Where to Begin" in the Installation Guide (Part 2).
Attention The labeling on some drives could direct you to the wrong figure below. One family of 7200RPM drives has an IBM logo on the top
of its label followed by "Fireball Plus AS". For these drives refer to the Quantum Figure below. Two families of Maxtor drives, clearly labeled
Maxtor D540-4K or D740-6L were developed by Quantum before it was absorbed by Maxtor. For these drives also refer to the Quantum Figure.
As a check, look at the jumper pins and jumper setting information on the drive. It should look similar, but not necessarily identical to the "Set
A" information in the corresponding figure of this supplement. The information in this supplement is provided to document jumpering capabilities
not always covered by the drive labels.
