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.

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

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!
