I have successfully written a CD using the HP cd writer. I had to make only the 2 changes I mentioned in my last post. I have a dedicated hard drive for the CD mastering, and I have a Pentium-90 with 32 megs of ram. I supped -current this morning and installed a current kernel on my 2.1R machine. Some notes: The HP CD-R is on its own controller (an AHA1542CF). I could start up X, recompile the kernel while starting a couple of netscapes, etc... and it still worked. (I did all of this stuff with the laser off, but it still kept up with the drive) One sort-of wierd thing was that the CD-R stayed in dummy mode even though I didn't tell it to the second time. The docs I have say something about removing the medium resetting this stuff, so I ejected and put it back in and it wrote fine... (630 megs or so...) I also got the newest version of mkisofs from some linux site somewhere and used that. I used: mkisofs -d -a -N -l -R -T -v -A "This is a Test" -P "Written by JJARRAY" -o /cdmaster/image.iso /cdbuild (where cdbuild has the directory tree I want on the cdrom, and cdmaster is another partition on the dedicated CD disk) I then used the vn driver to examine the contents of the iso9660 filesystem. I didn't even waste any CD's !! Many thanks to everybody involved in getting this working!!! Here's the shell script I used to write the CD... I don't know if the sleeps are necessary but I stuck them in anyway... (The rtprio etc. line specified in the wormcontrol man page is a bit wierd...) #/bin/csh -x wormcontrol select PLASMON RF4100 sleep 1 wormcontrol prepdisk double sleep 1 wormcontrol track data sleep 1 rtprio 5 team -v 1m < /cdmaster/image.iso | dd of=/dev/rworm0 obs=20k sleep 1 wormcontrol fixate 1 Fred.
