Example:
The partition size required for a system with an installed memory size of 1GB (1,024MB) and a full
installation of the operating system:
6,300MB + (1,024MB * 1.5) + 1,024MB + 300MB + application size
= 9,160MB + application size.
If the partition where the operating system is installed is smaller than that required to install the OS
and paging file, expand the partition size or utilize a larger disk. If your system does not have a
sufficient dump file size, divide the required file space into multiple disks by performing the steps
below:
1.
Set the partition size to a size sufficient to install the OS and paging file.
2.
See "Setting for Solving Problems" to write the debug information of the dump file on to
another disk.
If there is not enough disk space to write the debug information, add another disk for the dump file.
