 Posted: Wed Oct 01, 2003 10:05 pm Post subject: dvd and cdrw drives show up as cdrom |
 |
|
So I finally got my system to read both my drives, but the problem is that I want kde to know that the first drive is a DVD drive and the Second is a CD-RW. It thinks they are both CDROM.
dmesg | grep hd returns
| Code: | hda: WDC WD400BB-75AUA1, ATA DISK drive
hdb: WDC WD800BB-00CAA1, ATA DISK drive
hdc: LITEON DVD-ROM LTD163, ATAPI CD/DVD-ROM drive
hdd: _NEC CD-RW NR-7800A, ATAPI CD/DVD-ROM drive
|
and here is my fstab:
| Code: |
# /etc/fstab: static file system information.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.13 2003/07/17 19:55:18 azarah Exp $
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hdb1 /boot ext2 noauto,noatime 1 1
/dev/hdb3 / reiserfs noatime 0 0
/dev/hdb2 none swap sw 0 0
/dev/hdc /mnt/dvd iso9660 noauto,user,ro 0 0
/dev/hdd /mnt/cdrom iso9660 noauto,user,ro 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0
|
and my devfsd.conf:
| Code: |
# Uncomment this to let PAM manage devfs
#REGISTER .* CFUNCTION /lib/security/pam_console_apply_devfsd.so pam_console_apply_single $devpath
# Autoload the sg module if generic scsi driver compiled as module.
#LOOKUP ^sg$ MODLOAD ACTION sg
# Give the cdrw group write permissions to /dev/sg0
# This is done to have non root user use the burner (scan the scsi bus)
#REGISTER ^scsi/host.*/bus.*/target.*/lun.*/generic PERMISSIONS root.cdrw 660
# General note for the following auto creation of symlinks:
#
# If you change the device that the symlink points to,
# you should also remove the symlink before restarting
# devfsd
# Create /dev/cdrom for the first cdrom drive
LOOKUP ^cdrom$ CFUNCTION GLOBAL mksymlink cdroms/cdrom0 cdrom
REGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL mksymlink $devname cdrom
UNREGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL unlink cdrom
# Create /dev/dvd for the second cdrom drive
# (change 'cdroms/cdrom1' to suite your setup)
# NOTE: We add the fully qualified path here, else some apps
# have problems to resolve the true device (drip comes to mind)
LOOKUP ^dvd$ CFUNCTION GLOBAL mksymlink ${mntpnt}/cdroms/cdrom1 dvd
REGISTER ^cdroms/cdrom1$ CFUNCTION GLOBAL mksymlink ${devpath} dvd
UNREGISTER ^cdroms/cdrom1$ CFUNCTION GLOBAL unlink dvd
# Create /dev/cdrw for the first cdrom on the scsi bus
# (change 'sr0' to suite your setup)
#LOOKUP ^cdrw$ CFUNCTION GLOBAL mksymlink sr0 cdrw
#REGISTER ^sr0$ CFUNCTION GLOBAL mksymlink $devname cdrw
#UNREGISTER ^sr0$ CFUNCTION GLOBAL unlink cdrw

i guess i'm just unclear on what they mean by scsi emulation and what I should do to make the cdrw section work. also shouldn't kde recognize that my dvd drive is not a cdrom?
thanks

From the Gentoo install docs:
| Quote: | | If you have an IDE cd burner, then you need to enable SCSI emulation in the kernel. Turn on "ATA/IDE/MFM/RLL support" ---> "IDE, ATA and ATAPI Block devices" ---> "SCSI emulation support" (I usually make it a module), then under "SCSI support" enable "SCSI support", "SCSI CD-ROM support" and "SCSI generic support" (again, I usually compile them as modules). If you also choose to use modules, then echo -e "ide-scsi\nsg\nsr_mod" >> /etc/modules.autoload.d/kernel-2.4 to have them automatically added at boot time. |
| Quote: | | Important: If you set up SCSI emulation for an IDE cd burner earlier, then to get it to actually work you need to add an hdx=ide-scsi fragment to the kernel line in grub.conf (where "hdx" should be the device for your cd burner). |
or for lilo you need to add append="hdd=ide-scsi" after your kernel section.
So... in your case you need to do (or make sure you have done) three things:
1. enable kernel module support for ide-scsi
2. enable autoloading of the modules at boot time
3. pass "hdd=ide-scsi" to the kernel at boot time through grub or lilo
I'm not sure about the KDE issue, but it might not change. For all practical purposes, a DVD-ROM is a CD-ROM capable of reading large disks.
