Hard Disk Upgrade Kit

Most computer systems manufactured before 1994 do not allow you to access
the full capacity of IDE hard drives without a software solution or BIOS
upgrade.  If you system was made prior to 1994 you will probably need to
install Ontrack Disk Manager to access the full capacity of your Western
Digital hard drive in DOS and Windows/Windows for Workgroups 3.1x
environments.

There are two text files provided on the Ontrack Disk Manager diskette: 
README.CAV addresses system specific issues, and WDCDRV.DOC addresses 32
bit disk access driver issues.

Ontrack Disk Manager is only intended for use with DOS and Windows/Windows
for Workgroups 3.1x.  It provides quick installation and adds performance
and functionality to your PC.  Its quick installation capabilities
eliminate the necessity to manually partition your hard drive via the FDISK
program and logically format it via the FORMAT program.

Ontrack Disk Manager is used to access the full capacity of your Western
Digital hard drive.  Some computer systems will not allow you to access the
full capacity of IDE hard drives.  Ontrack Disk Manager software is
provided as one solution to overcome the 528 MB barrier.

Ontrack Disk Manager can be used for DOS and Windows/Windows for Workgroups
3.1x environments.  It cannot be used with the following operating systems;
Unix, Novell Netware, OS/2, Windows NT and OS/2 for Windows.
