Jerome Fine replies: Are you saying the actual CD image was available as opposed to the many files that are on the CD? I have the RT-11 CD sent from Tim Shoppa, so I am satisfied it is OK. BUT, I also want to burn my own CD in the same manner. ALSO using Windows 98 (Yeck). If anyone wants a copy, please ask! The RT-11 Freeware CD is composed of somewhat less than 212,992 sectors (of 2048 bytes each) which contain about 403 MBytes (Windows 98 Explorer says 21,223 files in 969 Directories using a total of 403,733,960 bytes) all contained under (if I have been told correctly) the ISO file structure for a CD. Starting at sector 212,992 on the CD, there are 114,688 sectors which hold 7 RT-11 partitions of 33,554,432 bytes each for a total of 234,881,024 bytes. These sectors can be accessed only by software which understands the RT-11 file structure, in particular programs such as PUTR, VMS Exchange and of course RT-11 itself. I can duplicate the above combination. I can copy files to a CD into an ISO file structure. I can also copy a file on the hard disk (which contains RT-11 files under the RT-11 file structure) to either a CD-R or a CD-RW starting at sector zero. BUT, Can anyone help me? I want to copy that same file to a CD-R or a CD-RW starting at sector 212,992 (just like Tim Shoppa did) after I have written the files to the CD under the ISO file structure. Of course, I want to be able to do this under Windows 98!! Does anyone know if that is even possible, let alone how it could be done?
