To begin an installation or upgrade with the most common options, simply wait 60 seconds or hit [Enter].

• Install or upgrade an existing system
  Do a basic install or upgrade. Try this option first
  vmlinuz initrd=initrd.img
• Install system with basic video driver
  Do a basic install or upgrade, but use the basic (vesa) video driver. Use this if you are having video card problems.
  vmlinuz initrd=initrd.img xdriver=vesa nomodeset
• Rescue installed system
  Boot into a text based rescue mode shell. If you already have linux installed on the machine, this will attempt to mount the drives for you.
  Note: The rescue image is on the boot.iso (network install) image as well as the normal DVD's. When it asks you where the rescue image is, you can select "Local CD/DVD".
  vmlinuz initrd=initrd.img rescue
• Boot from local drive
  Don't do any install, just boot off the local drive.
  .localboot 0xffff
• Memory test
  Run memtest to check the memory of your computer
  memtest

Boot command line options

This is also where you can pass options to the installation program to make it perform differently.
Options should be passed by hitting [Tab] and then typing in the option at the end of the line.
Then hit [Enter] to boot with those options.
