IBM’s 8.4 GB Deskstar offers a choice of two sets of jumper configurations so that the drive will function properly
on the widest range of systems. In some systems, the drive’s maximum usable capacity will not exceed 7.9 GB.
The following instructions will enable you to determine if your system has this limitation and will show you how to
provide the best configuration for many systems not designed to use a drive larger than 2 or 4 GB.
1. Choose your jumper setting from the configurations in the set labeled 16 Logical Heads. This allows the drive
to tell your system that its capacity is 8.4 GB.
2. Return to the User’s Guide and follow instructions beginning with Step 4 on page 1-3 in the Quick Installation
Guide (Part 1) or beginning with “What to Do Next” on page 2-9 in the detailed Installation Guide (Part 2).
3. If you follow the steps in the User’s Guide, and your drive IS recognized by the configuration-setup program,
complete the installation using the steps in the User’s Guide. If a lesser capacity is reported, you will need to
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 your interface and power supply
connections. Next, attempt to disable the autodetection facility of your setup software as described on page
2-20 of the User’s Guide. If your drive is still not working correctly, return to step 5 here.
5. Your system may be unable to start because the setup program in your BIOS is unable to operate correctly with
a drive that identifies itself as 8.4 GB. You must therefore switch the configuration jumpers on the drive to the
appropriate choice in the set titled 15 Logical Heads. (Your option includes a small bag with a third jumper if
you need it.) The 15 Logical Heads jumper setting allows the BIOS to treat your drive as a 7.9 GB drive.
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 2. Placing the Call to IBM” on page 3-11 of the User’s Guide.
This hard drive requires the latest OS/2 driver enhancements to utilize its full capacity. Go to the OS/2 Device Driver Web
page (OS/2 Device Driver Pak) located at http://service.software.ibm.com/os2ddpak/html/index.htm to obtain the OS/2
hardfile updates. Select “OS/2 Component Updates.” Select “Installation Diskette Updates.” Then select “Greater than 4.3
GB IDE Hardfile Support.” Next, download the “idedasd.exe” file. (Read “helpful instructions” for download instructions.)
Follow all the instructions in the “readme” included in the “idedasd.exe” file to install the hardfile updates. Use the
diskettes to install the driver enhancements that allow OS/2 to utilize the full capacity of the 8.4 GB hard disk drive.
