Greetings! I'm trying to find out how a MS-DOS workstation knows what type of diskette drives are installed WITHOUT checking the physical characteristics of a diskette mounted in the drive. I plan on running a program at network login to set environment variables according the type of disk drives installed, but I can't plan on the user (a student) to have a disk in each drive (or any disks at all). I know that AT's and better save this information in CMOS, but have no idea where and how that information is stored. Also, this doesn't help me with the still large installed base of PC/XT class systems still in use. So, how does DOS know what floppy drives are installed? Format seems to find this info pretty easily, even when a non-standard drive requiring a device driver is used. How can I read and interpret this info? Thanks. -- ----------------------------------------------------------------------------- Mark Medici ** Systems Programmer III * Rutgers University Computing Services medici@elbereth.rutgers.edu * medici@cancer.BITNET * !rutgers!elbereth!medici My opinions are not necessarily my employers'. *Reality is context-sensitive.
