I'm using a program called FDformat : at the moment which does wonderful stuff like format 1.2M diskettes to : 1.5M etc etc, I'd like to be able to use these under OS/2 but the driver : required relies on normal handling of int13 so doesn't work under OS/2 at all You can use some of the diskettes formatted with fdformat on O/2 2.x without any special handling. You just can't format them. The option does not exist in the floppy disk driver IOCTL packet. In particular, you can read and write the 18-sector 5.25" and the 21-sector 3.5" diskettes. You will have problems with the 10-sector 5.25" because OS/2 will insist on double-stepping. Bear in mind that you will NOT be able to use these diskettes under Warp. The diskette driver was reworked to allow the 18??-kiloybyte distribution format and in the process the other extended formats were disabled. -- =========================================== MSDOS on a '386 is a waste of good silicon.
