CD burning in kernel 2.6 without scsi emulation.

Please everyone forgive me if this is covered elsewhere - I have searched the forum but can only find a few references.
Basically, I've been looking around trying to figure out how to burn in kernel 2.6 without scsi emulation. It says you can do it - but I wasn't sure how.
Anyway, below are the steps I took to get it working. I don't use any kind of front end when burning cd's, so maybe some programs have ways of making this easier, I don't know. I'm sure most people know about this already, but it'd be good to just have a little guide somewhere - especially seeing as 2.6 is on arch 0.6 iso.
1. First of all, the command I pass to lilo is changed from "hdd=ide-scsi" to
"hdd=ide-cdrom"
2. Check what address your burner is at:
cdrecord dev=ATAPI -scanbus
This gives me an address of 0,1,0 - might be different for others
3. After making an iso as usual, just initiate burning with
cdrecord -v dev=ATAPI:0,1,0 speed=8 *.iso

Hope this helps someone!

Re: CD burning in kernel 2.6 without scsi emulation.

oddly enough despite having tried two different burners i have to still use scsi emulation to burn.  if i don't i get piles of errors and the burning process dies before it starts. i tried two burners.....my old cd burner and my new dvd burner.

Re: CD burning in kernel 2.6 without scsi emulation.

In 2.6 my burner worked straight away, without having to add any lines to the lilo.conf
So I dunno if that command is completely necassary
So yeah, I needed no configuration whatsoever to get my burner working with k3b and xcdroast...arson might be another matter though

Re: CD burning in kernel 2.6 without scsi emulation.

I also didn't need a boot parameter to get my CD burner working with 2.6. My gotcha was adding the option dev=ATAPI when using cdrecord. That was not immediately obvious.

Re: CD burning in kernel 2.6 without scsi emulation.

Yes, you're right it's not immiediately obvious! I was unclear about how differnt software would handle this in the new kernels...I just couldn't get tcdr working which was previously fine with scsi-emulation.
I'm sure the all the steps I took aren't necessary - as wakeupbomb and rls say - but I thought it would be helpful to have a thread covering this specifically.

Re: CD burning in kernel 2.6 without scsi emulation.

ATAPI thing doesn't work with cdrdao which i use more often  sad

i have to go back to loading the scsi mods

Re: CD burning in kernel 2.6 without scsi emulation.

slyski ,

are you sure about that i was sure i heard someone ranting online that the newest version had ATAPI working. you may want to visit their homepage to find out.

Re: CD burning in kernel 2.6 without scsi emulation.

AHHHSOOOO!

after furthur review and actually reading the man of cdrdao it does state using the ATAPI:x,x,x thing.

when i first read this post i just implimented the cdrdao scanbus command and it came up empty.

but, after further thought the use of scanbus in cdrdao and cdrecord is quite silly in this regard  :?:
you should be able to apply the command as needed and run with it.

thanks sarah

Re: CD burning in kernel 2.6 without scsi emulation.

no problem. it was just a well timed post really as that is one of the few things from irc in the last week that i remember.

it took me a bit to get all the info for cdrecord straight before i finally was able to burn with ATAPI.

Re: CD burning in kernel 2.6 without scsi emulation.

and after more further reveiw:

what becomes of ide-scsi emulation - is there another use for it or has it just suddenly became deprecated??

i believe i need the other scsi stuff for my camera to hook up to /dev/sdax.

also when when i went 2.6.3 my mouse left skid marks across my screen - i had to slow it down.
was that my imagination? i was usin kde at the time. i switched to gnome now just to test run it. will  post a printing problem later about it.

hiho hiho, off to work

Re: CD burning in kernel 2.6 without scsi emulation.

i think some usb stuff still uses it and possibly it is there for legacy hardware support. i dunno i only ever needede it for burning before.

Re: CD burning in kernel 2.6 without scsi emulation.

The ide-scsi module is specifically for ATAPI IDE drives (just about all of them now).  USB devices are SCSI devices, so don't need "emulation".

Re: CD burning in kernel 2.6 without scsi emulation.

when i recompiled a custom kernel about a week ago i took a peek at the ide-scsi help section and found that it is still used for special situations. such as for drives that do not fit under any other catagory and need special setup.

so it seems not to be totally deprecated after all.

thanks for all,
slyski

Re: CD burning in kernel 2.6 without scsi emulation.

I'm running kernel 2.6.5 with no "scsi-ide" emulation.

I have a Sony 32x/10x/40x CDRW drive.  In the past, using a 2.4.x kernel and "ide-scsi" emulation, I was able to write at 32x (or thereabouts).

Now, at best, I write at 16x, and "XCDRoast" gives me warnings that writer performance may be slowed by NOT using the "ide-scsi" emulation.

It's a minor inconvenience.  I thought the 2.6.x kernel made the "ide-scsi" emulation "obsolete".  I checked the FAQ and manual from the "XCDRoast" website, and they don't seem to address this issue.  All my drives use DMA.

I have no problems writing CD's, but just not at the maximum my writer will allow.  Anyone have similiar experiences, and a solution?

Re: CD burning in kernel 2.6 without scsi emulation.

I think that at one point Linus Torvalds said that ide-scsi for CD burning was crap and wondered why it wasn't changed earlier, so yes, it's probably deprecated.

Re: CD burning in kernel 2.6 without scsi emulation.

so what are magic dev names of these CDRW devices now?
/dev/sg0
/dev/scd0
?

I sure can not find what they are, hence no burning at all under 2.6.5


Off to using Peanut and Slackware, no hard feelings but I need my CD to burn, PDA and scanner to connect and arch won't do it.

Re: CD burning in kernel 2.6 without scsi emulation.

i was having huge probs with this - could not get xcdroast to work with scsi emulation or ATAPI - in the end i tried it with cdrecord with ATAPI settings, as per all the advice, and it worked perfectly first go, all goes - xcdroast is crap methinks!
