tasks:
• Defined the environment variables for the default system partition. For more
information about describing your system configuration, see the description
for Set default environment variables . . . in Section 3.4.3.
• Described your system configuration to the firmware. For more information
about describing your system configuration, see the description for Set
default configuration . . . in Section 3.4.3.
• Provided the required system partition on your hard disk. For more
information on creating the system partition, see Section 3.4.5.
The following table specifies the free space and file-system requirements for
installing Windows NT:
Item Free Space Required File-System Requirement

System partition must be FAT.
The system partition is the disk partition that contains the hidden files
OSLOADER.EXE and HAL.DLL in the subdirectory \OS\WINNT351. If the system
partition is large enough, it can also contain Windows NT, or you may choose to
use a separate partition. The system partition and Windows NT may be on
different hard disks.
