Modules question

[Thomas E. Dukes]

Hello,

About a year ago, I installed an ide CDRW.  I added the following lines to
modules.conf:

options ide-cd ignore=hdb
pre-install sg     modprobe ide-scsi # load ide-scsi before sg
pre-install sr_mod modprobe ide-scsi # load ide-scsi before sr_mod
pre-install ide-scsi modprobe ide-cd # load ide-cd   before ide-scsi

Since upgrading from RH 9 to FC 2, I now get "fatal error" at boot up for sg
module. What is the sg module?  The reason I ask is that under RH 9, I
always got an error about sound.  My mother board does not have sound nor do
I have a sound card.  So I'm sure that's why I got the sound error under RH
9.  

Is the sg module for sound?  If so, can I comment it out without affecting
the operation of the CDRW?

TIA
