 Hi,   6 I have just put CDWRITE13_VMS up for anonymous FTP on ) v36.chemie.uni-konstanz.de in [.cdwrite].   @ CDWRITE13_VMS writes a files-11-structured container file onto aC recordable CD. I have thrown off the option to produce an audio CD. > The produced disk is mountable on every VMS-system without any special drivers.  < I've tested the program with OpenVMS/VAX 6.1/DEC C V5.3-006/B Vaxstation 3100 M38 and I'm pretty sure that this program will run fine on any Alpha, too.   H Writing a CD is a nontrivial task especially in a multiuser environment.H Just look into the FAQ for CD-writing. I recomment a standalone machine,I though I've developed and tested on a clustered VAXstation. Then dismount G the SCSI-disk on all machines but your cdwriter machine before burning.   H Special thanks to Wolfgang J. Moeller, who helped me by looking into theG sources of OpenVMS and encouraged me to use a slow VAXstation 3100 for   CD-writing.   # You'll need the following hardware:   A A 700-1000 MB SCSI disk, directly connected to the machine with a 	 SCSI-Bus. F A Phillips (CDD2000) or HP 4020i CD-Writer (The original linux program< supports more drives here and it is up to you to modify the 2 source if you like! Please send me this version!).  # You'll need the following software: M Install the DECUS-vddriver and generate on a container-file of a size smaller G than 650 MB (restriction: select a multiple of 100 Blocks, because this I is build in here). Initialize the SCSI disk with the switch /index=beginn   to get 650 MB contiguous space.    Now install a virtual disk:   7 $ copy nl: disk:[dir]VDA1.DSK/ALLOCATE=XXXXX/CONTIGUOUS , $! i.e. I use 1327100 for xxxxx = 647,998 MB& $!
