I am looking for a mod to XENIX mkdev to support creation of filesystems on 1.44 Mb floppies... Any help would be appreciated. Please reply via mail to gatech.edu!fabscal!dorn Dorn

Any help would be appreciated. As of Xenix 2.2.2, (I think), if you run "mkdev fd" it will prompt you for 48tpi/9sect, 96tpi/15sect, or 135tpi/9sect. The 3.5" floppy devices, for double density mode (720K) are the same as 96tpi/9sect, in other words /dev/fd096ds9 is the same as /dev/fd0135ds9. Since the 3.5" drives can be plugged into the same cable the 5.25" drive is on, they really are plug compatible. You will have to use /etc/default/tar settings of blocking=18, size=720 though. What I'd like to know is if anyone has successfully used 1.44 meg (DS/HD) 3.5" floppies under Xenix. Either my drive is only rated for 720K, and/or the Xenix driver can't handle 1.44 meg yet. I did notice that SCO is only using 720K floppies for their distribution (for 2.2.X anyways) so that may say something... -- Jim Morton, APPLiX Inc., Westboro, MA UUCP: ...harvard!m2c!applix!jim jim@applix.m2c.org
