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

459: If you can't boot from a CD or a floppy disk,

468: To make a boot floppy under MS-DOS, use the "rawrite" utility located
469: at <i>CD1:5.2/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
470: use the
