In reply to Karl's posting and to several others that mailed replies: 1) Evidently Disk Manager doesn't write the partition info. in a way XENIX likes; I deleted the DOS partition and recreated it with DOS FDISK. Now I can boot DOS by typing "dos" at the XENIX boot prompt. 2) The diskette writing problem seems to be an incompatiblilty between my old (1985) WD AT hard/floppy controller and XENIX-386. More experimentation has shown me that when XENIX writes to either floppy (a 1.2 M one as A: and a 1.44 M one as B:) every odd-numbered byte written is a zero. It doesn't matter whether the floppy is a DOS floppy formatted under DOS and written with doscp or a XENIX floppy, for example, tar'ing to /dev/rfd0 (= /dev/rfd096ds15). XENIX won't format a floppy on this system, because the superblock contains every other byte zero. I currently write floppies by copying files to the DOS partition using doscp and then booting DOS and copying from the hard drive to a floppy (DOS writes diskettes just fine on this machine). Has anyone had a problem like this? I have a Western Digital S100013 (I think) hard/floppy controller running in a 16 MHz iSBC-386 computer from Intel (it drives the bus at 16 MHz). The controller has revision no. "X1". I tried my other machine's controller, which is identical to the first one, with identical results. 3) I compiled JOVE and another EMACS under XENIX-386, as well as ARC. Is there a place that I can post the binaries for those without the developers' kit?

In my last posting, the sentence "it drives the bus ad 16 MHz" should have been "it drives the bus at 8 MHz."
