Re: Secondary Slave CDROM Detection / Configuration

I found a solution the problem. I'm not entirely sure if it's the only
way to solve it, but it works for me.

The optical drive info: Optiarc DVD RW AD-7530A

Solution: LILO

I stumbled across a discussion thread with an identical bug. It seems
that Grub has trouble correctly loading the ata_piix module (please
correct me if I'm wrong).

I missed the important log message in the dmesg output:

ATA: abnormal status 0x7F on port 0x00010177

Dances with crows:
I didn't provide the laptop make and model, since it's a Eurocom and
many people are not too familiar with these laptops. I also, didn't
bother with the distribution information, since I thought it's a low
level kernel problem. It appears that the device cannot be (at least
from any sensible way) set to master mechanically. I don't think the
Master/Slave was the problem, though.

Does this laptop have a make and model#? That information is vital to
solving your problem.

I cannot use my CD/DVD burner since it's configured as a slave device
on the secondary IDE channel (by itself). As a result, I cannot locate
the device in dmesg, lspci, etc...

lspci reports devices on the PCI bus, so you'd see the IDE chipset
there, not IDE devices. IDE devices all match hd.* , so dmesg | grep hd
should return something. Unless you're trying to use the not-ready-yet
libata-PATA support.

I'm curious to know if there's a workaround to get the device working
in Linux.

Provide the make and model# of the laptop, the name of its IDE chipset,
and the distro name and version.

I know the optical drive works; I successfully installed Linux from
it.

Using which version of which distro?

I've read that [a drive] must be set up as a master, if it's on [its]
own ide channel. However, I cannot do this from the bios, and I have
no idea where the jumpers are, if they even exist.

They'd be on the drive itself. Remove it from its Ultrabay or
equivalent, look on the back near the IDE connector.
