For example, if the mounted memory size is 512MB, the partition size will be calculated by the
above formula as follows:
1000MB + (512MB * 1.5) + (512MB + 12MB) + Application Size
= 2292MB + Application Size
Dividing into the partition of the recommended size into multiple disks as written below will solve
problem that it cannot be reserved in one disk.
1.
Set the "Size required for installation + Paging file size".
2.
See Chapter 5 and set that debugging information (equivalent to the dump file size) is to
be written to a separate disk.
(If the disk does not have enough free space to enable the dump file size to be written,
then after installing the system using the "Size required for installation + Paging file size",
install an additional new disk.)
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'.
