The utility creates a bootable floppy drive, so you will need a USB
floppy drive since most of the newer thinkpads do not have floppy drive
built in.
The other hitch is that the hibernation file must be in the first
primary, FAT formatted partition of the hard disk. The partition size
needs to be at least the amount of RAM installed plus ~35MB.
Set up the disk thus:
1st primary: C: FAT
Boot Manager
OS and data partitions (D:, E:, ....) This may mean you will need
to reinstall eCS.
Boot to the DOS utility disk and select the option to create a
hibernation file. (Ignore any warnings about OS/2 not being supported)
