This directory contains image files that can be used to create media
capable of starting the $PRODUCT installation process.
The boot.iso file is an ISO 9660 image of a bootable CD-ROM. It is useful
in cases where the CD-ROM installation method is not desired, but the
CD-ROM's boot speed would be an advantage.
To use this image file, burn the file onto CD-R (or CD-RW) media as you
normally would.
The diskboot.img file is a VFAT filesystem image that can be written to a
USB pendrive or other bootable media larger than a floppy. Note that
booting via USB is dependent on your BIOS supporting this. It should
be written to the device using dd.
