INSTALLATION GUIDE
2. Use the Data Lifeguard Install software to access the full capacity of the hard drive with
these jumper settings. To run Data Lifeguard Install:
- Insert the Data Lifeguard Tools diskette into your floppy disk drive.
- Boot your system and use the Data Lifeguard Install software (see page 17 for detailed
instructions). This will install EZ-BIOS on your system and allow your system to access
the full capacity of your hard drive.
8.4 GB Barrier
There is an 8.4 GB hard drive limitation on some traditional system BIOSs. To access the full
capacity of 8.4 GB and larger hard drives, your system BIOS must support extended BIOS
functions, and your operating system must recognize extended BIOS functions. It is difficult
to determine if your system BIOS supports 8.4 GB or larger hard drives. We recommend
using the latest Data Lifeguard Install software to ensure support of the full capacity of your
hard drive. Visit our product support Web site at support.wdc.com for the latest version.
Other options are to upgrade your system BIOS or purchase a controller card. Contact your
system or motherboard manufacturer for a BIOS Flash or more information.
