Attention: Read First - IBM ATA-100 (EIDE) Hard Disk Drive User’s Guide Supplement
If you are using Microsoft Windows 3.1, Windows 95, or Windows 98: Disregard this section on setting drive configuration jumpers;
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 Workstation, Microsoft Windows 2000 Professional, Microsoft Windows Millennium Edition
(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.

Troubleshooting
If you follow the steps in the User’s Guide, and the configuration-setup program recognizes your drive at its true capacity, partition
and format your drive using instructions given in the “Partitioning and formatting your drive” section in the User’s Guide.
If the configuration-setup program reports the drive capacity as smaller than what it actually is, you must use Disk Manager to access
the full capacity of the drive using the instructions in the “Partitioning and formatting using DiskManager” section in the User’s Guide.
If you are using Microsoft Windows 2000 or Windows Me, when DiskManager requires the selection of an operating system choice, select
Windows 98 and choose to format and partition with FAT 32.
If your drive functions incorrectly after you restart your computer, check to make sure that the drive interface cable and the drive
power supply cable are connected correctly. Next, attempt to disable the auto-detection facility of your setup software as described in
“Step 1. Solving Problems” in the User’s Guide Appendix B.
If your drive continues to function incorrectly after performing the above actions, your computer might have problems starting up
because the setup program in your BIOS cannot correctly identify your high-capacity drive. To solve these BIOS problems, you must
reconfigure the jumpers on your drive to the desired setting selected from Set B in the figure that corresponds to your disk drive. This
will reduce the capacity that your BIOS sees so it can recognize your drive. You must use DiskManager to access the full capacity of
the drive using the instructions in the “Partitioning and formatting using DiskManager” section in the User’s Guide.
If your computer still functions incorrectly, contact the IBM HelpCenter
IBM” in the User’s Guide Appendix B.
