Re: Map of boot procedure

[Aaron Mulder <ammulder@alumni.princeton.edu>]

As far as I can tell SuSE 10 uses hotplug.  It seems to handle network
drivers, mounting various devices (USB sticks, perhaps CD-ROMs?), the
bluetooth module in my laptop, etc.  I have next to 0 understanding of
how it actually works under the covers.  I have noticed that it writes
various things to /etc/sysconfig/hardware/ -- a file named for each
device it detects and that file seems to contain the proper driver to
load for the device.  If you can figure out whether your sound card is
listed there (comparing ID via lspci or something), then you can check
and see if you can override the driver listed or whatever.  For what
it's worth, I've used SuSE 10 with both laptops and desktops and
haven't had this problem, though I don't think I've used it with an
audigy card.
