I wrote a series of archive disks under Xenix that now I don't think I can read under ISC 2.0.2. When switching from Xenix to ISC 2.0.2 I tarred many files to rfd096ds9 or something like that. This should have been 96 track per inch, double side and 9 sectors per track under low density mode, for a total storage of 720K per disk. What a surprise when I loaded ISC 2.0.2 and found that they have 48TPI/ds/9sect (360K) and 96TPI/ds/[9 15]sect (1.2M). But no 5 1/4 format that would produce a 720K floppy. I assume (from what I can tell) that the 96 TPI format regardless of the sector count is a high density format. I ran through most minor device number flags looking for what I need, but didn't find it. Anyone got any ideas? On another porting issue, I configured the first disk partition (UNACTIVE) for msdos, second (ACTIVE) partition, unix. dosette (Unix) won't access the first partition, did I miss something? Thanks and a handshake to all responders, Dave Roland usenet ..!rochester!cci632!ccird7!dsr

Ok, you have to mount the partition as an MS-DOS partition. As root: mount -f DOS /dec/dsk/0p1 /mnt ^ ^----------(partition no.) |________ (fixed disk no.) now access that drive through /mnt. Look in Appendix A. in ICS/ Unix Primer. Dante cmcl2!dasys1!super68!dante
