Server install boot options

[Monte Milanuk]

Hello,

I'm curious about the boot options during the server install immediately
following selecting the language. The ones labeled 'F1, F2,...F6' at the bottom
of the screen. I can't seem to find any usable information in the official
documentation, and what I can find in the community docs seems to apply to the
desktop live cd version, as the options are different from what I'm seeing when
booting from the server install cd.

Specifically, the option 'F4 Modes' used to be for selecting graphics modes, but
now contains options 'Normal', 'OEM Install', 'Install minimal system', and
'Install minimal virtual machine'. And 'F6 Boot Options' used to contain various
parameters for booting with funky hardware... it still does, but has two other
options 'Expert' and 'Free Software Only' which are similarly unexplained as to
what exactly they do.

Where can I find some documentation that covers what those options actually do,
etc.? Seems like some important options to be left completely out of the
official documents...

Thanks,

Monte
