Re: [TCLUG:3733] modules won't load automatically (fwd)

[Peter Lukas <peter@math.umn.edu>]

Modules that aren't automagically loaded (scsi, network, sound, etc) are
generally called from /etc/conf.modules.  Chances are that this was
somehow overwritten or is no longer queried as the machine comes up.  A
RedHat 5.2 system (or anything using modprobe) requires /etc/conf.modules
to contain information about the sound and ethernet cards, for example.
I'm assuming you made modules and made modules_install, and they're now in
/lib/modules/preferred which is actually a link to 
/lib/modules/kernel-version underneath which are the compiled modules for
network, filesystems, scsi disks, soundcards, etc. If there is no
conf.modules and the appropriate path to the modules isn't set,
modprobe assumes that the path is /lib/modules/`uname -r`  The format for
the conf.modules files is pretty simple.  Here's what mine looks like (I
am running a highly-modularized 2.1.131):
  # I can't boot without this guy.
  alias scsi_hostadapter aic7xxx
  # I don't like appletalk and ipx.
  alias net-pf-4 off
  alias net-pf-5 off
  alias eth0 eepro100
  # I want full-duplex 100mbps!
  options eepro100 options=0x30
  # How else to hear mp3's?
  alias sound sb
  options -k sb io=0x220 irq=5 dma=1
  alias midi opl3
  options -k opl3 io=0x388

Also, consult the man pages for depmod and modprobe for more help with the
conf.modules files.
