about loading / blacklisting / ... modules
Hi
"With a little help from" this list I am now able to view the
boot-messages on my laptop.
After reading through this I realise I still have much too learn and
that there might be some problems with my current config.
Could you please take a look at these warnings/errors and let me know if
and how I should fix them?

>> If I understand this correctly the i810_tco module should be loaded
because hardware requiring this has been detected but the module isn't
available.
Where can I read about all these modules (what they do, when they're
needed etc.)?
Fri Nov 26 22:28:09 2004: Loading 8139too module.
Fri Nov 26 22:28:10 2004: Skipping already loaded module piix.
>> Messages like these can be ignored right? I assume it just means a
certain module is requested twice but only loaded once.

Fri Nov 26 22:28:11 2004: Skipping unavailable/built-in usb_uhci module.
>> I don't understand why usb_uhci isn't marked as blacklisted, in
/etc/hotplug/blacklist there's a line "usb-uhci" are these two different
modules or should the line in /etc/hotplug/blacklist be corrected?

>> the modprobe: FATAL scared me a bit at first but since this laptop
doesn't contain a floppy drive I assume it doesn't matter much... Or am
I wrong? Is there a way (other than to compile my own kernel) to
prevent my system from trying to load this module?
