451: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
452: release is on CD1. If your BIOS does not support booting from CD, you will need
453: to create a boot floppy to install from. To create a boot floppy write
454: <i>CD1:5.2/i386/floppy52.fs</i> to a floppy and boot via the floppy drive.
455:
456: <p>
457: Use <i>CD1:5.2/i386/floppyB52.fs</i> instead for greater SCSI controller
458: support, or <i>CD1:5.2/i386/floppyC52.fs</i> for better laptop support.
