There is a
hcl button at the top of this page, which stands for Hardware Compatability List.
In that section you'll find some posts, and
this one is my post concerning the HP 920C, which is almost identical to the HP 930C. Follow those same instructions and you'll be printing in no time.
You don't list your soundcard, so help is going to require you to do some research. First, as root, do
# lspci
which will list your PCI devices and something that looks like this
Code:
02:0b.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)
will be your soundcard.
Using that information, go to the
ALSA website. From that main page, under Latest Software Releases download the three files - Driver, Library, and Utilities from the column Stable release. While they're downloading, select
Supported soundcards and find the one that the output of # lspci listed. Gigabyte's website only lists Realtek ALC650 codec for your sound, but that's not enough information.
I've never setup a 56K modem in *nix, because I have broadband and use a router with an ADSL modem. There are also some
modems listed in the HCL guide.
Hope this helps, as I wanted my 1,000th post to be worthwhile. Whatever help you still need, post back.
