AFAIR /dev/pg0 is a device used for IDE devices connected via the parallel
port (I had to use it to connect my second CD-ROM writer HP8100e).
Have you installed the paride driver? It is not required for internal IDE
CD-Writer.
AT the moment I have no access to my box with CD-writer, I can check
the details of configuration on monday and send you the message.
But what I remember:
The ATAPI/SCSI emulation should be enabled (read the help for this option,
AFAIR it requires disabling some IDE functions).
In the SCSI section of kernel configuration I have:
<*> SCSI support
--- SCSI support type (disk, tape, CD-ROM)
<*> SCSI disk support
<M> SCSI tape support
<*> SCSI CD-ROM support
<*> SCSI generic support
Your CD-Writer should work as CD-ROM drive and be available as /dev/scd0
(or /dev/scd1 and so on, depending on how many SCSI devices have you installed
in your box). Are you able to mount the CD_ROM? Try to do it as root:
mount /dev/scd0 /cdrom -t iso9660
AFAIR the IDE CD-Writers are serviced as Generic SCSI devices, so you should
have
created /dev/sg0, /dev/sg1 and so on (use /dev/MAKEDEV for this purpose, or
create them manually. Below are their attributes:
crw------- 1 root root 21, 9 lip 29 1998 sg9

I'm very surprised, that your cdrecord complains about /dev/pg0
it should complain about /dev/sg0 (or similar)...
Run the cdrecord as root, or create a group "cdrecord", change the ownership
of /dev/sg* devices too the group "cdrecord", allow RW access for group and
add yourself to the "cdrecord" group.

I'll forward this message back to the group, maybe if I've said somthing wrong
somebody will correct it before you blow up your machine :-).
