IBM ATA-3 - Manual (Page 17)

The largest partition size that you can create under the DOS, Windows
95, Windows 3.x, and OS/2 operating systems that use 16-bit file
allocation table (FAT) conventions is approximately 2.14 GB.
3 When
you are installing a drive larger than 2.14 GB, you must create more
than one partition to use the full capacity of your drive.
If you are using the high performance file system (HPFS) conventions
with OS/2, see your operating system documentation for partition
sizing information.
To create the maximum partition size (2.14 GB) when you are using
the DOS based FDISK utility to partition your drive, you must enter
the partition size as 2047 MB.

Determining What to Do Next
After you complete the hardware installation, you must partition and
format your new drive before you can use it.
If the drive you are installing will be your primary drive (the
drive that contains the operating system) and you will NOT be
using the Disk Manager BIOS, insert the first operating system
installation diskette into the diskette drive; then restart the
computer and follow the onscreen prompts.
If you do not have operating system installation diskettes, see the
documentation that comes with your operating system.
If the drive you are installing will be your primary drive (the
drive that contains the operating system) and you WILL be using
the Disk Manager BIOS, insert the Disk Manager Diskette into
the diskette drive; then complete the following steps:
1. Turn on the computer.
2. At the " Welcome to Disk Manager " banner, press Enter.
3. Read messages and press Enter to continue.
4. At the Disk Manager Main Menu, select Easy Disk
Installation and press Enter.
4 When software such as FDISK refers to memory capacity, MB means 1 048 576 bytes.
