16.8-GB EIDE HDD - Jumper settings


The IBM Enhanced IDE 16.8 GB Hard Disk Drive offers a choice of jumper configurations, so that the drive will function properly on the widest range of computers.
In some computers, the BIOS will not recognize a hard disk drive reporting more than a 2.1 GB capacity.
The following instructions will help you determine if your system has this kind of BIOS, and what configuration settings your computer requires.
  1.  Locate the jumper configuration settings label on the back of your drive. Use a jumper setting from the  Normal Use set in order for the drive to tell your system that its capacity is 16.8 GB.
  2.  Return to the User's Guide  and follow instructions beginning with Determining Where to Begin in the Installation Guide (Part 2).
  3.  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 the Drive  section in the User's Guide.
     If the configuration-setup program reports the drive's capacity as smaller  than what it actually is, you must use Disk Manager to access the drive's full capacity.
  4.  If your drive seems to lockup or hang after you restart your system, check the computer's interface and power  supply connections.
     Next, attempt to disable the autodetection facility of your setup software as described in

      Step 1. Solving Problems - in the (paper) User's Guide Appendix B.

     If your drive is still not working correctly and performing the above actions, continue to step 5.

  5.  Your computer may have problems starting up because the setup program in your BIOS cannot correctly  identify your high-capacity drive. Change the configuration jumpers on the drive to the correct selection in the  set titled 2 GB Clip, illustrated above.
     If you need a third jumper for your setting, look for an extra jumper in  a small bag, included in your option package.
     The 2 GB Clip jumper settings allow the BIOS to treat your  drive as a 2.1 GB drive, which prevents BIOS problems when you start the computer.
     Return to the User's Guide as directed in step 2 above and attempt to complete the installation again.
     You will need to use Disk Manager to access your drive's full capacity. If your system still locks up or hangs, refer to

      Step 3. Placing the Call to IBM - in the (paper) User's Guide - Appendix B.
