Backing up a harddisk in Linux

I want to create lots of DOS machines with old 386's and 486's and I don't see myself sitting with old stiffies and floppies installing DOS on each machine. So I decided to go for the option of installing the harddrive of the DOS machine I want to create and taking an image file of the original singing dancing games, worprocessing, killer DOS machine an reimaging this second harddrive from this image.

Here are some good links of Free Linux tools

Free Hard Disk and Partition Imaging and Backup Software
backing up entire hard disks or partitions using dd

Looks like partimage will be the way to go
