The live system does not require any space on your hard disk. However,
existing Linux swap partitions on the disk will be used if available.

See the FAQ for more information; this document is available at the Ubuntu
web site, http://www.ubuntu.com/

Thank you for choosing Ubuntu!

Press F1 for the help index, or Escape to exit help.F3BOOT METHODSAvailable boot methods:

Try Ubuntu without any change to your computer
  Start the live system. If you wish, you can install it later using the
  "Install" icon on the desktop.
Install Ubuntu
  Start the installation.
Test memory
  Perform a memory test.

("Ubuntu" may be replaced with other related operating system names. This
help text is generic.)

To use one of these boot methods, select it from the menu with the cursor
keys. Press F4 to select alternative start-up and installation modes. Press
F6 to edit boot parameters. Press F6 again to select from a menu of
commonly-used boot parameters.

Except in expert mode, non-critical kernel boot messages are suppressed.

Press F1 for the help index, or Escape to exit help.F4RESCUING A BROKEN SYSTEMThere is no dedicated rescue mode on this disc. However, since the disc
provides a complete user environment, it is possible to use the command-line
and/or graphical tools provided to rescue a broken system, and to use a web
browser to search for help. Extensive advice is available online for most
kinds of problems that might cause your normal system to fail to boot
correctly.

Press F1 for the help index, or Escape to exit help.F5SPECIAL BOOT PARAMETERS - OVERVIEWOn a few systems, you may need to specify a parameter by pressing F6 in
order to boot the system. For example, Linux may not be able to autodetect
your hardware, and you may need to explicitly specify its location or type
for it to be recognized.

For more information about what boot parameters you can use, press:

<F6F6>   boot parameters for special machines
<F7F7>   boot parameters for various disk controllers
<F8F8>   boot parameters understood by the bootstrap system

Many kernel modules are loaded dynamically by the bootstrap system, and
parameters for those modules cannot be given on the command line.

Press F1 for the help index, or Escape to exit help.F6SPECIAL BOOT PARAMETERS - VARIOUS HARDWAREYou can use the following boot parameters by pressing F6, in combination
with the boot method (see <F3F3>). If you use hex numbers you have to use
the 0x prefix (e.g., 0x300).

HARDWARE                               PARAMETER TO SPECIFY

IBM PS/1 or ValuePoint (IDE disk)      hd=cylinders,heads,sectors
Some IBM ThinkPads                     floppy.floppy=thinkpad
Protect I/O port regions               reserve=iobase,extent[,...]
Laptops with screen display problems   vga=771
Force use of generic IDE driver        all_generic_ide=1

Possible (temporary) workarounds for lockups or other hardware failures:

disable buggy APIC interrupt routing   noapic nolapic
(partly) disable ACPI                  acpi=noirq or
acpi=off
disable USB                            nousb
poll for interrupts                    irqpoll

Press F1 for the help index, or Escape to exit help.F7SPECIAL BOOT PARAMETERS - VARIOUS DISK DRIVESYou can use the following boot parameters by pressing F6, in combination
with the boot method (see <F3F3>).

HARDWARE                     PARAMETER TO SPECIFY

Adaptec 151x, 152x           aha152x.aha152x=iobase[,irq[,scsi-id[,reconnect]]]
Adaptec 1542                 aha1542.aha1542=iobase[,buson,busoff[,dmaspeed]]
Adaptec 274x, 284x           aic7xxx.aic7xxx=no_reset (enabled if non-zero)
BusLogic SCSI Hosts          BusLogic.BusLogic=iobase
Certain DELL machines        aic7xxx.aic7xxx=no_probe

This list is incomplete, see the kernel's kernel-parameters.txt file for
more.

Press F1 for the help index, or Escape to exit help.F8SPECIAL BOOT PARAMETERS - INSTALLATION SYSTEMYou can use the following boot parameters by pressing F6, in combination
with the boot method (see <F3F3>). These parameters control how the
bootstrap system works.

RESULT                                  PARAMETER

Disable ACPI for PCI maps (handy for some HP servers and Via-based machines)
                                        pci=noacpi
Use Braille tty                         brltty=driver,device,texttable

you! We are especially interested in hearing about startup problems, because
in general they don't happen to only one person. We've either already
heard about your particular problem and can dispense a quick fix, or we
would like to hear about it and work through it with you, and the next user
who comes up with the same problem will profit from your experience!
