I've 2 SATA HD, a dvd writer and kernel 2.6.11.11
just installed. I'm no more able to find the right device
for my dvd writer. In /dev there is a device cdrom
as link -s to /dev/sg1, but it's a character device,
not a block devise, so I cannot mount the CD/DVD.
Maybe there is some mistakes in my kernel,
but I'm not able to find a solution...
Have I to choose (as modules or static)
the ATA/ATAPI/IDE support? SCSI support
for generic devices and cdrom doesn't solve...
Some suggestions?

Thanx!
MS

The only thing I know is that u don't have to use SCSI emulation at all.
I'm still running 2.4 kernel.
sorry.

Most likely you need to link /dev/cdrom to dev/hdc, since scsi-ide emulation
isn't normally used with the 2.6.X kernels. Call it a feature. Oh yes,
when you go to use something like "cdrecord -scanbus dev=ATA" to see what
your dvd is actually detected as to write to it.

With 2.4 it's detected as hda (and sda and sdb the 2 hd),
but with 2.6 I've no hdx devices!

For a while I had some ub_ devices. They eventually became sd_ when I
got a newer 2.6. Check for ub_, sd_, sr_, hd_.

Do you have a /dev/sdc or /dev/sdd? What are your harddrives mounted as in
dmesg? What ever they are, your dvd with be one or two letters up in the
alphabet.

Try commenting out the /dev/hdx = ide-scsi line out of your lilo.conf. I
lost my cdrom device when I upgraded to kernel 2.6.11.10 and commenting
out that line seemed to work.

Now it's seen as hda

Thanx!

What mistake??? pls explain, so we ("I" in this case) can know, and
dont do the same.
Im wondering about this because i want to compile the last 2.6 kernel...

I forgot to compile Generic PCI bus-master DMA support,
choosing: - Use PCI DMA when available
- Silicon Image chipset,
or the chipset of yout MOBO
