Did "modprobe ide-scsi" and scsi_mod was also loaded. Then "modprobe sg".

"cdrecord -scanbus" said:

0,0,0     0) 'PHILIPS ' 'PCRW804         ' ' 2,1' Removable CD-ROM

And I wrote the CD image with:

cdrecord -v speed=4 dev=0,0,0 output.iso

This 188MB NetBSD live CD image took six minutes.

Then to look at it:

modprobe sr_mod
mount -t iso9660 /dev/scd0 /mnt # or scd1

(sr is used for SCSI CDROM support. sg is SCSI generic as used by cdrecord.)

Once I couldn't read a big file off of the CD, so I did it again. (Maybe I need to look at the verbose details more closely to see why.)

Then later: It took 19 minutes to blank the CD. (Next time do "fast".)

cdrecord -v blank=all dev=0,0,0
#time cdrecord -v blank=fast dev=0,0,0

To look at ISO image:

modprobe loop
mount -t iso9660 -o loop output.iso /mnt

After working all night, I had my first live cd-based system :) I've been compiling lots of notes in a separate document: live-cd.html.

My CD has full base distribution, working XF86Config (using standards and VESA).
