People looking for cdwrite 2.0 (uuencoded) or patches to run under AIX 4.1.4 can find them here.

Also of interest is mkisofs 1.05 (uuencoded) to create ISO 9660 filesystems. And some patches to make it compile cleanly under xlc.

This software currently only works with a Yamaha CDR100 CD-writer (since it is the only drive I have), but it should be possible to modify it to work with other drives. The routine "cdr100_open" should be changed to recognize product id's other than "CDR100" and the routine "cdr100_ioctl" should be changed to generate the appropriate scsi mode select commands. If anyone does make these changes, please forward your changes to me and I will try to incorporate them here. NOTE THAT THE DEVICE DRIVER IS NOT PUBLIC DOMAIN. You may modify it for your own personal use, but you cannot distribute the modified code in any form (executable or source code) and it may not be used as part of any commercial product. It is supplied "as is" without warranty of any kind.

I'm trying to do several things here.

First, I don't want someone making a buck off of my work, it's free to whoever wants to use it.

Second, there's no warranty, if it writes defective CDs or makes your system crash, it's not my problem (but it seems to work OK).

Third, if you make a change, you can't pass that on to a third party. You can send the change to me and if it makes sense I'll add it to my distribution. This helps on the first point because you would want to modify it if you were to sell it, and I expressly forbid distributing modified code; and on the second point because I know my code works (for the most part) and I don't want code that I haven't seen being distributed with my name on it.

So use it all you want, but if you make a significant change others might find useful, then let me know; and if you tell someone about the driver and other programs, point them to my web page rather than giving them your copy of my code.

Build the device driver using these files:

Makefile

cdr100.h

cdr100_dd.h

cdr100_trace.h

cdr100_t.c

cdr100_t.exp

cdr100_b.c

cdr100_b.exp

make -f Makefile install

Build the configure method using these files:

makefile

debug.h

cdr100.h

cfgcdr100.c

cdr100.msg

cdr100.add

make -f makefile install

odmadd cdr100.add

Here is a tar file containing these files as well as the patches.

You should now be able to use SMIT to configure the Yamaha CDR100.

Then get cdwrite-2.0.tar.gz and uncompress/untar it (requires GNU zcat):

zcat cdwrite-2.0.tar.gz | tar xvof -

Then apply the patches (requires the patch utility):

cd cdwrite-2.0

patch -s < cdwrite-aix.patch

make

You will need to change DEFAULT_DEV in the Makefile for your drive.

Precompiled binaries of cdwrite, isosize and mkisofs for AIX 4.1.4 are available.

Try "cdwrite -v -e" (this will eject a disk from the drive) as a first test.

(cdwrite must be suid root or you must change the protection of DEFAULT_DEV to 666).
