216 Start-Up<br />

1. The program checks if the BIOS provides VESA 2.0–compliant framebuffer<br />

support and boots the kernel accordingly.<br />

2. The monitor data (DDC info) is read.<br />

3. The first block <strong>of</strong> the first hard disk (MBR) is read to map BIOS IDs to Linux<br />

device names during the boot loader configuration. The program attempts to<br />

read the block by means <strong>of</strong> the the lba32 functions <strong>of</strong> the BIOS to determine if<br />

the BIOS supports these functions.<br />

If you keep Shift pressed when SYS<strong>LINUX</strong> starts, all these steps are skipped. For<br />

troubleshooting purposes, insert the line<br />

verbose 1<br />

in syslinux.cfg for the boot loader to display which action is currently being performed.<br />

If the machine does not boot from the floppy disk, you may need to change the boot<br />

sequence in the BIOS to A,C,CDROM.<br />

External Boot Devices<br />

Most CD-ROM drives are supported. If problems arise when booting from the CD-<br />

ROM drive, try booting CD 2 <strong>of</strong> the CD set.<br />

If the system does not have a CD-ROM or floppy disk, it is still possible that an external<br />

CD-ROM, connected with USB, FireWire, or SCSI, can be used to boot the system.<br />

This depends largely on the interaction <strong>of</strong> the BIOS and the hardware used. Sometimes<br />

a BIOS update may help if you encounter problems.<br />

9.2.2 Installation Fails or Machine Does Not<br />

Boot from the Installation Media<br />

There are two possible reasons for a machine not to boot for installation:<br />

CD or DVD-ROM Drive Unable to Read the Boot Image<br />

Your CD-ROM drive might not be able to read the boot image on CD 1. In this<br />

case, use CD 2 to boot the system. CD 2 contains a conventional 2.88 MB boot<br />

image that can be read even by unsupported drives and allows you to perform the
