You mean these?
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2

Scsi is used for expensive hard drives and cd-roms. If you have a "normal" computer you won't need this. *Unless* you've been trying to emulate an scsi interface to be able to use a cd-writer?

Anyway, if your hard drives and cd-roms work, you have nothing to worry about.

/sbin/modprobe scsi------is enabled by default on Slackware install. goto /etc/rc.d/ an open rc.modules up in text editor and comment that particular line out, an Slack won't look for these devices when it boots up.

Thanks for the replies. The strange thing is that the command 'mount /dev/cdrom /mnt/cdrom' does not work. I have to type 'mount /dev/sr0 /mnt/cdrom' I am not sure if my burner will work properly as it claims that it is mounted read-only. I don't remember running into this problem before. Does anybody have any ideas? Here is my fstab file :

/dev/hdb7 swap swap defaults 0 0
/dev/hdb10 swap swap defaults 0 0
/dev/hdb9 / ext3 defaults 1 1
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

Do I just need to change the 'ro' in '/dev/cdrom' to 'rw'?

if you've only one cd device just change the




my line is

/dev/sr0 /mnt/cdwriter iso9660 noauto,user,rw 0 0

and for my dvd just the normal

/dev/cdrom /mnt/cdrom iso9660 noauto,user,ro 0 0

well remember that /dev/cdrom it is usually the symlink for the real device, could be /dev/hdc... etc... so the common thing to do it is just ck if it that's a symlink with a simple
$: ls -al /dev/cdrom
so if it is just do make a symlink

about the burner... i recommend you to compile the scsi emulation support (under IDE ATA and ATAPI block devices) module, then under SCSI support the modules SCSI CD-ROM Support and SCSI generic support (could be as a module), and this one (SCSI generic support) will load the module called sg.o, when you are going to burn something... and your cdrw will usually be /dev/sg0, but the /dev/sr0 will work cuz it is the scsi emulation for the cdrom (to use it as the burner)... and if you want to probe the cdrw to work just do a simple

$: cdrecord -scanbus

anyway i recommend you to read the CDRW How To.

good luck,
