Creating Partition Size
The minimum size for the partition that the system is to be installed can be calculated from the
following formula.
Size necessary to install the system + Paging File Size + Dump File Size
Size necessary to install the system = 1000MB
Paging File Size (Recommended) = Installed Memory Size * 1.5
Dump file Size
IMPORTANT:
The above paging file size is necessary for collecting debug
information (memory dump). If you set the default value of
paging file size smaller than the 'recommended' value, the accurate
debug information (memory dump) may not be collected.
The maximum paging file size which can be set on one partition is
4095MB. If the above paging file size exceeds 4095MB, specify
4095MB for the paging file size.
The dump file size for the system with more than 2GB memory
mounted is '2048MB + 12MB'.
If you install any application program or the like, add necessary
space to the partition to install these programs.
For example, if the mounted memory size is 512MB, the minimally required partition size will be
calculated by the above formula as follows:
1000MB + (512MB * 1.5) + (512MB + 12MB) = 2292MB
NOTES:
If you want to install using Express Setup, calculate the minimally
required partition size as follows:
If you do not apply Windows 2000 Service Pack
The larger value of either one: 'Minimum Partition Size' described
above, or '4095MB'.
If you want to apply Windows 2000 Service Pack
The larger value of either one: 'Minimum Partition Size' described
above + 850MB or '4095MB'.
