CD Writing in 2.5.51

Hi,

So many howto's for writing in 2.4.x, simply put, what do i need (kernel-wise) to get IDE CD writing going?

the lwn.net announcements dont really explain what needs to been done, what modules need to be loaded (and what I dont need anymore) etc.

You don't need any additional modules. Just don't activate ide-scsi by either not appending ide-scsi/scsi=hdX or not compiling ide-scsi support in the kernel.

You also need a recent version of cdrtools. Just take the latest cdrtools-2.0pre version. cdrdao won't work yet without moving the new libscg from cdrtools to cdrdao, but it's not too hard to do and if you complain on the cdrdao list they will perhaps update it themselves sooner ;-)
After that is done you can burn your disks with dev=/dev/hdX.

Markus

can i completely remove scsi support then? (I dont have any scsi device)

-mdew

Yes.

Markus

awesome, i got it to work, thanks.. tho I'm now trying to enable the DMA on the drives... (unsuccessfully)

Perhaps CONFIG_IDEDMA_ONLYDISK is set? Or you don't have compiled in the specific driver for your chipset?

yeah my mistake, CONFIG_IDEDMA_ONLYDISK was selected, fixed..thanks for help dude..much appreciated.

Any idea why I can't get a CDRW to be read yet I can happily burn and read a CD-R? Do I have to access the CDRW through a different device and/or mount a fs for CDRW?

When I load a burnt CDRW the system complains of bad media yet no problem under w2k.

I'm using a UJDA720
