Bootable CD-ROM support uses the ``El Torito'' extension of the ISO 9660 standard. It identifies a boot file on the CD-ROM, and then emulates the floppy disk drive on your computer to load the file and boot the system.
To boot directly from the installation CD-ROM, the system must allow you to specify CD-ROM as a boot device in the system BIOS, and must not use a proprietary CD-ROM boot scheme.
To boot from a SCSI CD-ROM drive, set the SCSI controller so that BIOS support for bootable CD-ROM is enabled. You must also select ``boot from SCSI'' in the system BIOS. Once the SCSI BIOS and the system BIOS are set, put the bootable CD-ROM in the CD-ROM drive and boot the system.
To boot from an ATAPI CD-ROM drive, you must ensure that your system BIOS is new enough to support booting from a CD-ROM. Set the boot sequence of your system BIOS to start with the CD-ROM drive. Once the system BIOS is set, put the bootable CD-ROM in the CD-ROM drive and boot the system.
Some systems do not allow you to choose the CD-ROM as a boot device in the BIOS, or have not implemented bootable CD-ROM support. In these cases, you will need to use the boot floppy disk provided with the system.
