Creating the Hibernation File
Warning:
The hibernation file must not be
created in a compressed data
area of the hard disk or external
drive.
When installing the operating system, or if you have expanded the
computer memory, you must create a hibernation file on the hard
disk drive to use hibernation mode.
The size of the hibernation file will be greater than total memory.
For example, if base memory is 8MB and you have installed an
optional 4MB IC DRAM card, the hibernation file is 13MB: (8MB
plus 4MB) plus 1MB.
The following describes how to create a hibernation file for your
operating system.
