I've seen a lot of posts about getting the Sony CDU-55E ATAPI CD-ROM drive to work under
Linux. Since I just got mine running, I thought it might be worthwhile to lay out the
rough spots I encountered. Those who don't think newbies should be coddled like this,
please direct flames to /dev/nul!
My understanding is that the 1.1.86 kernel was the first to support the CDU-55E. I used
the 1.1.90 kernel. The first twist is in the make config procedure. Be sure to answer
"y" to the questions, "Include new IDE driver for secondary i/f support?" and "Include
support for IDE/ATAPI CDROMS?"
Second twist: after you've made zImage, look for it buried down in the
/usr/src/linux/arch/i386/boot directory. If you wonder why there is a nice vmlinux image
in the /usr/src/linux directory, where you started (that is too big for LILO), and the
zImage that's small enough to boot is buried like that, well, you're not alone!
The last twist is figuring out where to look for the CD-ROM instructions. Take a look at
the README.ide file in the /usr/src/linux/drivers/block directory. Note that you may need
to chmod the referenced MAKEDEV.ide1 script file before running it. I took the line
mount /dev/cdrom /cd -t iso9660 -o ro
and put it in a separate mountcd script file. If you'd prefer to remember the mount command
syntax and flags, feel free!
