Linuxers,
Thanks to all who have reported recent experience with Linux 2.2.1
and CD writers. Thanks for a job well done to the CD-Writing HOWTO editor,
Winfried Trumper <[EMAIL PROTECTED]>. My recent installation of a CD-Writer
has been rendered practical by reference to others' experience found in
dejanews and elsewhere.
Since the frequency of questions is still high, I suspect that
this summary may be useful as a single source of pointers, despite
incompleteness. I will submit another summary when installation is
complete (est. 99-03-15), and further details are available by mailing
to me direct.

upgrading to at least linux-2.0.36.

* Discoveries
linux-2.0.35 does not support SCSI Ultra 2 Wide.
linux-2.0.36 reportedly provides support.
I upgraded to linux-2.2.1.
pppd-2.2.0 is incompatible with linux-2.2.1.
linux-2.2.1:linux/Documentation/Changes lists the minimum
required version of various utilities.
I upgraded to pppd-2.3.5.
PPPD-2.3.5 INTRODUCES SOURCE DEPENDENCY INTO THE LINUX-2.2.1 KERNEL!!!
pppd-2.3.5 supplies headers that REPLACE and add to the
linux-2.2.1 kernel source.
I await the next upgrade that eliminates this dependency.
linux-2.2.1 is too large for some purposes
make zImage failed.
make zdisk failed.
make bzImage succeeded.
lilo-0.16 is incompatible with bzImage.
lilo-0.21 succeeded.
cdrecord-1.6.1 requires SCSI CD Writer.
cdrecord-1.6.1 does not directly provide IDE support for
HP 8100i.
I compiled SCSI emulation in the kernel.
HP 8100i requires SCSI emulation.
SCSI emulation is required to wrap an IDE device for
with SCSI-only software like cdrecord-1.6.1.
I compiled SCSI emulation in the kernel.
I compiled SCSI generic driver in the kernel.
workman reads /dev/cdrom by default.
/dev/cdrom is linked to /dev/hdc by default?
When using SCSI emulation, the first cdrom probably
appears as /dev/scd0
sudo rm /dev/cdrom required.
sudo ln -s /dev/scd0 /dev/cdrom succeeded.
/dev/sr* is required.
cd /dev; sudo ./MAKEDEV scd0 succeeded.
* Tests
data read
# insert a known good data CD
mkdir -p /cdrom
sudo mount -t iso9660 /dev/scd0 /cdrom
ls /cdrom # Should list known contents
sudo umount /cdrom
audio read
# insert a known good audio CD
sudo workman -V 0
SCSI address determination
cdrecord -scanbus
CD RW format
# Insert a CD RW
sudo cdrecord -v -v -v -multi dev=1,0,0 blank=all
multi-session data read (incomplete)
# Insert a disk packet-written under Win95
sudo cdrecord -v -v -v -multi -toc dev=1,0,0
# This produced a reasonable toc
# I don't know how to read or decipher the track.
track-at-once data write
# Generate a filesystem image
mkisofs -r -o /var/tmp/cdimage.iso9660 /archive
# Test the image
sudo mount -t iso9660 -o ro,loop=/dev/loop0 \
/var/tmp/cdimage.iso9660 /cdrom
cd /cdrom;
for f in `find . -type f; do cmp $f /archive/$f; done
# Record the image
# Close all applications and suspend all nonessential processes
sudo cdrecord -v speed=2 dev=1,0,0 /var/tmp/cdimage.iso9660
# Wait ~40min
# Reload and test the image
sudo mount -t iso9660 /dev/cdrom /cdrom
cd /cdrom
for f in `find . -type f; do cmp $f /archive/$f; done
sudo umount /cdrom

* Remaining Tasks
Upgrade all utilities the minimum versions required by linux-2.2.1.
Fix module problem (... can't locate module net-pf-5 ...).
Fix ftape problems.
* Remaining Questions
Who is working on a pppd upgrade to disentangle its source
dependency from the linux kernel?
Who would like to help me investigate disentangling the pppd source
from the linux kernel?
What errors or omissions are in the above?
How can one read and decipher under linux a track packet-written
(multi-session) under Win95?
How does one packet-write a (multi-session) disk?
Good luck,
