Unhappy improve burn with Xcdroast & CDRW1610A Philips?


When I started Xcdroast and selected my burner I got a warning that sounded like this:

"You have selected an ATAPI device as your cd-writer. This is not recommended setup. You will eperience long delays within XCdroast and bad performance. See FAQ for how to properly install scsi-emulator for best results."

Where are these FAQ, since with the app downloaded didn't come ?

You added the burner after you installed? Well, maybe Redhat 7.2 wasn't advanced enough to auto configure as scsi-emulated? No worries, I added a burner to 7.0. You need to add scsi emulation as the API to the burner. Here was what I used as a reference...

http://www.justlinux.com/nhf/Hardwar..._to_Linux.html

If the burner is the ONLY cd drive on your system, then likely, it is hdc (you can see if if you 'more /etc/fstab'), what you want to do is...

1. Become root.
2. Add the following line to the end of your /etc/rc.local:

insmod ide-scsi

1. Add the following line to the end of your /etc/lilo.conf file:

append="hdc=ide-scsi"

Where "hdc" might be "hdb" or "hdd" depending on where your drive is installed. This instructs the kernel to access the cd-writer via the scsi emulation driver.

1. Reconfigure LILO by running the following command at the Unix shell prompt:

lilo

Skip the part about cdrecord, because you very likely have it installed. Test with
cdrecord --scanbus
it should now show your burner and you can start xcdroast and not get the error.

Then...

If you want to read with the recorder, you will need to add or modify the appropriate line in /etc/fstab so that the drive is addressed through the ide-scsi interface. The following worked for me, but the device name may not be correct for all distributions, and in any case reading is beyond the scope of this document.

/dev/scd0 /cdrom auto defaults,ro,noauto,user,exec 0 0

When you get to the last part, post your /etc/fstab, and I or others will tell you what you need to add.

RO

P.S. Any particular reason for 7.2 as opposes to 8.0 or 9.0? It has come a long way since 7.2.
P.P.S Here was the FAQ. http://www.xcdroast.org/xcdr098/faq-a10.html#2
Ignore ANY reference to investigating the kernel. The support is there unless you recompiled it.

Exclamation

This is my fstab:
Label=/ / ext3 defaults 1 1
/dev/hda2 /d1 vfat defaults 0 0
/dev/hda7 /d2 vfat defaults 0 0
/dev/hda6 /d3 vfat defaults 0 0
none /dev/pts devpts gid=5, mode=620 0 0
none /proc /proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
LABEL=/rhbig /rhbig ext3 noauto 1 2
LABEL=/rhsml /rhsml ext3 noauto 1 2
/dev/hda8 swap swap defualts 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

Another question:

- where can I find what exactly should I put at the end of /etc/lilo.conf: "hdb", "hdc", "hdd" ?
- I found sth that looks like the driver for my cdrw in /proc/ide/ide1/hdd. Does this mean that I shoul put "hdd"

To RolledOat,

What happend? i'm expecting further explanations. I don't want to make faulty settings and as a result lose the abbility to use my cdrw for reading purposes. Another question: if let's say I might want to install another cdrom on my computer, are there any consequences related to the settings I will make for my cdrw?

Hello, I figured that someone else might follow up while I was away. Changing the fstab is step 3. Do the first 2 steps. which can easily be undone before we do your fstab.

Open a console
su - root <enter>
cp /etc/rc.local /etc/rc.local_orig <enter>
pico /etc/rc.local <enter>

Add the following line to the end of your /etc/rc.local:
insmod ide-scsi

cp /etc/lilo.conf /etc/lilo.conf_orig <enter>
pico /etc/lilo.conf <enter>

Add the following line to the end of your /etc/lilo.conf file:
append="hdc=ide-scsi"

lilo <enter>
cdrecord --scanbus <enter>
it should now show your burner.

RO.

Question

I tried what you suggested but after changing lilo.conf and running lilo I get the following error: duplicate append at line 18. My lil0.conf is:

prompt
timeout="50"
default=linux
boot="/dev/hda1"
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear

image="/boot/vmlinuz-2.4.7-10"
label="linux"
initrd="/boot/initrd-2.4.7-10.img"
read-only
root="/dev/hda1"
append="hdd=ide-scsi"


I guess that appending the line append="hdc=ide-scsi" conflicts with the look-alike line above.
Any solutions?
