Hola,
I am having an issue with scsi emulation. I have a fresh install of
RH7.2 (cause my drive with skipjack decided to die the other night :( ).
On first boot I noticed both my dvd and cdrw drives were listed on the
scsi chain 0,0,0 and 0,1,0 respectively. 

[spencer at conflict spencer]$ ls -l /dev/cdrom*
lrwxrwxrwx    1 root     root   9 Apr  9 23:06 /dev/cdrom ->  /dev/scd0
lrwxrwxrwx    1 root     root   9 Apr  9 00:58 /dev/cdrom1 -> /dev/scd1

When I try and burn mp3's to cdda with mp3burn I am able to successfully
do so. Then I put in a dvd and it is not recognized. If I reboot the box
and then put in a dvd the dvd works fine, but I can not burn a cd.
In the past I have always only used scsi emulation on the burner. I
added this to my modules.conf file

[spencer at conflict spencer]$ cat /etc/modules.conf
alias parport_lowlevel parport_pc
alias eth0 3c59x
alias sound-slot-0 emu10k1
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L\
>/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S\
>/dev/null 2>&1 || :
#####Stolen from the internet
options ide-cd ignore=hdb # tell the ide-cd module to ignore h
alias block-major-11 sr_mod # load sr_mod upon access of scd0
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

I was getting some errors in my syslog regarding the block-major-11
sr_mod, that is what prompted me to add these lines (the ones below
##Stolen from internet). I am getting frustrated with these two drives.
One try I _can_ burn a cd next try I make a coaster. ( I do drink alot
of beer, but I _don't_ need anymore coasters :) )
I will have to make this work consistantely, I have to, I just (finally)
got dvd::rip to work on this box. It is very cool. It does want a gob of
resources however. And I am suprised it even acts like it is working on
this AMD K6II 450.
Here is a snip from my syslog with a few errors.
