Windows 2000 Supports Large Hard Drives

Windows NT2000 system partition can be formatted as FAT file system ( max 2GB),
FAT32 file system ( max 32 GB) or NTFS file system ( max 2 terabytes) before
copying the Setup files. Finally, support for large drives. Windows NT 2000
supports large system partitions because it has the ability to use BIOS INT-13
extensions to boot the operating system on partitions with more than 1,024
cylinders, or 7.8 GB in size. After Windows NT2000 Setup copies files, it
restarts the computer to continue with GUI-mode Setup.

There can be problems. NT2000 setup does not verify that BIOS INT-13
extensions are enabled or available for use. If they are not, upon reboot, you
will get the following error message after POST:

       A disk read error occurred.
Press Crtl+Alt+Del to restart.

A similar problem occurs with SCSI controllers when drive translation is
disabled and INT-13 extensions are disabled in the SCSI BIOS.

In either case, with these features disabled, the drive’s geometry is native
and the drive’s partition table will contain Cylinder, Head, and Sector (CHS)
values which cannot be described within the partition table’s upper limit of
1,023 cylinders. INT-13 extensions must be used to boot from the partition.
