I am using USB cd writer. It is detected by my RH9.
I didn't burn cds yet but I played cd...

Do I have to change default in config file?
Thanks.
Michael.


CDR_DEVICE
The CDR_DEVICE is the scsi address of your CD-RW.
The default is: CDR_DEVICE="0,0,0"


IDESCSI=
If your CD-RW is on /dev/hdd and uses ide-scsi emulation then enter:
IDESCSI="hdd=ide-scsi"
The default is: IDESCSI="hdb=ide-scsi"

Hi,

I am the person who wrote LifeBoat. I have not tested it on a USB CD writer because I do not own one. You are the first person that I know of who has tried to use LifeBoat to burn a USB CD. So I guess you are my guinea penguin on USB CD writers.

I looked at the following link to see what is involved with writing CDs on a USB CD writer:
http://www.tuxmobil.org/linux_usb_cd.html

From what I read there I would say that CDR_DEVICE="0,0,0" should work just like it does for an IDE CD writer. If your CD writer is the first (or only) scsi device on your system then its device number is 0,0,0. If it is the second scsi device then its number is 1,0,0 and so on.

If you set the CDR_DEVICE parameter incorrectly then LifeBoat will not burn a LifeBoat CD.

I can only guess about IDESCI=. The purpose of this parameter is to tell the kernel to use the scsi modules for a device that is configured as IDE. If your USB CD writer is configured as a native scsi device then you do not need IDESCI and you should set it to null: IDESCSI= If your USB writer is configured as native IDE then you need an IDESCI parameter to tell LifeBoat which IDE device is being run as a scsi device.

The IDESCSI parameter is needed by the LifeBoat kernel at boot. If you set it incorrectly the only problem that will happen is that the LifeBoat rescue CD will not be able to write CDs, something that people rarely do in rescue mode anyway.

Also if you need the IDESCSI parameter then you also need it for your desktop kernel. You should have the parameter in your bootloader, either grub or lilo.

If you don't get LifeBoat to burn a CD on the first try or two then I suggest that you first learn to burn an ordinary ISO9660 data CD, then tell me how to do that on an USB CD writer and I could probably tell you how to make it work in LifeBoat.

In any case I would like you to let me know how things work out in detail so that I can do whatever is necessary to make LifeBoat work on USB CD.

Nice to meet you Mr. Creator!

Steve,
I post the same question on another forum since here was no
answers and I received one:

for me, I have an USB 2.0 CD-RW that just works out of the box. I plug it in, and X CD Roast just sees it.

What does (as root)

cdrecord --scanbus

show?

I did that. May the output will tell you something.

Looks like it will not work for me.
But I will try tomorrow at work and will let you know...

Hello Steve,
sorry,
yesterday my colegue took this removable writer and after didn't plugin the power.
Yesterday I run scanbus through ssh to my office RH....
)
I will try to create LifeBoat now.
Looks like everythinf is fine.
This is today's result:

Steve,
I created cd. When I boot computer hangs on line:

"What is wrong?"

The LifeBoat ramdisk is probably too big for your computer memory.

Set:
RAMDISK_SIZE=110

"cp: cannot stat `/bin/eject': No such file or directory"

You can probably get rid of these error messages by setting the DISTRO variable to the name of your distribution.

Also you shoule set the MYNAME variable to your name.
MYNAME=Michael
