Bootable CD-ROM support

You can boot directly from the installation CD-ROM. If you use this feature, you bypass the initial system load from the floppy disk and increase the overall speed of the installation.

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.

NOTE: SCO recommends that you use bootable CD-ROMs on SCSI based systems, because ATAPI CD-ROM drives often do not recognize bootable CD-ROMs.

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.

Pentium III Processor Serial Number

Pentium III processors include a processor serial number (PSN) feature. If enabled, the PSN can be read by applications. On UnixWare 7, the PSN is disabled by default. This feature allows administrators to turn on PSN support by adding a line to the file /stand/boot and rebooting the system. See boot(4).
