Special Considerations
Hard drives greater than 2.1GB may need to be divided into multiple partitions / logical drives. MS-DOS versions
4.0 through 6.22 allow a maximum primary partition / logical drive size of 2.1GB and are limited to 8.4GB in
physical drive capacity. The file systems supported by Windows-95, Windows-98 and Windows NT are not restricted
to the 8.4GB physical drive limit, but special BIOS support is required.
Hard drives greater than 8.4GB in capacity may be restricted to 8.4GB (or less) due to system BIOS limitations,
operating system limitations, or both. Check with your system manufacturer to determine if your BIOS supports
the correct extensions for hard drives greater than 8.4GB.
In order to achieve the Ultra ATA/66 transfer speed, you must have a system and BIOS that will support Ultra
ATA/66. The correct drivers must be loaded, and an Ultra ATA specific data cable must be used. The Ultra ATA
cables use the Cable Select method rather than a master / slave scheme, so the drive must be set with a jumper to
enable Cable Select.
