Repartition
Value: Yes | No
Specifies whether all partitions on the first drive on the
client machine should be deleted and the drive reformatted
with NTFS or not.
Warning: This is mostly useful when performing an
unattended installation from the bootable Windows 2000 CD-
ROM on x86-based machines. In all other cases, files
copied to that hard disk will be lost. On Alpha-based
computers in particular, the system partition will be
destroyed.
ExtendOemPartition
Value: 0 | 1 | <extra size in MB>
The ExtendOemPartition key is used to install Windows 2000
on a disk that is greater than 2 GB. This key causes text-
mode Setup to extend the partition on which the temporary
Windows 2000 source files are located into any available
unpartitioned space that physically follows it on the
disk.
The temporary installation source MUST be a primary
partition and limited to 1024 cylinders only. Writing
beyond cylinder 1023 will cause the installation to fail.
0 indicates that the partition will not be extended, 1
indicates that it should be extended to fill out the hard
disk and <extra size in MB> specifies the extra amount of
space to be added to the current partition size. When the
value is 1 or <extra size in MB>, the FileSystem key must
be set to ConvertNTFS.
