Installation:
· Extract the zip file in the root of a partition.
· The directories bin, etc and lib will be created.
· Boot DOS without EMM386 and start PM_LOAD </ROOT_PARTITION> from a IDE partition with a supported filesystem.
· </ROOT_PARTITION> is the device which will be mounted as root. Example: /hda1 - IDE primary master HD, first primary partition · /hdd5 - IDE secondary slave HD, first extended partition
