I have SCO Xenix 2.3.2 and all of the disk recovery procedures mention the "Emergency Boot Floppy" which the Installation Instructions are supposed to tell me how to make one. I can't find any such directions in the documentation set. If anybody knows, what is the specific manual and page number? Blind as a bat apparently, Jack Benzel jack_benzel@hpfcla.HP.COM

Thanks for the responses shown below!
I too almost never found this passage. It is in the System Administrators
Guide under "Using Floppy Disks and Tape Drives". Good luck.

I think ``mkdev floppy'' does the trick.
It creates a single-floppy file system, with some (not all!) necessary
programs. You'll have to scan it, and see if all's there, cat, ls, rm, etc.
etc.

More responses: mkdev fd Then follow the bouncing ball. You may have problems if you have a large number of devices on your system since your /dev directory is cloned on the floppy with the exception of /dev/root ... I have edited /usr/lib/mkdev/fd to eliminate all the multi-port devices so as not to fill up the inodes on the floppy.

Its the System Admistrator's Shell. A program actually. One of the menu options (its menu driven), is create a boot floppy. Mark DiVecchio

I remember that the 2.3.2 Xenix SysAdmin Guide was the same, so I'd suggest looking under section 16.3.4 (Making Filesystems on Floppy Disks). In the doc rev I have it's on pg 16-10 in the Installation and Maintenance Guide. Yes, it's well disguised and hidden, but it's there. The simple answer to your question; do a mkdev fd and answer the prompts (which is what a "man mkdev" tells us), or it should be accessible off a sysadmsh option if you'd prefer to go through a few extra layers of sfw to get to the same place. I'd suggest mounting your resulting bootable/rootable when you're done and adding any commands you personally might find useful, noting that your requirements may differ from mine and you may have to remove some files (unecessary to you) to make room - carefully. Here's my (lr) list from back when I was using Xenix. Salt & pepper to taste - carefully. Won't hurt to fsck it after you're done when you umount it. ==== bin boot dev etc mnt tmp xenix ./bin: cp dd dumpdir fsck restor rm sync vi ctar dparam ed l restore sh tar ./dev: cga fd096ds9 lp0i rfd048 rhd01 swap clock hd00 lp1 rfd048ds8 rhd02 systty cmos hd01 lp1f rfd048ds9 rhd03 tty color hd02 lp1i rfd048ss8 rhd04 tty01 colour hd03 lp2 rfd048ss9 rhd0a tty02 console hd04 lp2f rfd096 rhd0d tty03 d1057all hd0a lp2i rfd096ds15 rhd0root tty04 dsk hd0d mem rfd096ds18 rhd10 tty05 ega hd0root mono rfd096ds9 rhd11 tty06 erct0 hd10 monochrome rfd1 rhd12 tty07 error hd11 nrct0 rfd1135ds18 rhd13 tty08 fd0 hd12 nrct2 rfd1135ds9 rhd14 tty09 fd0135ds18 hd13 null rfd148 rhd1a tty10 fd0135ds9 hd14 ram00 rfd148ds8 rhd1d tty1A fd048 hd1a rct0 rfd148ds9 rinstall tty1a fd048ds8 hd1d rct2 rfd148ss8 rinstall1 tty2A fd048ds9 install rd1057all rfd148ss9 rmt tty2a fd048ss8 install1 rdsk rfd196 root u fd048ss9 kmem recover rfd196ds15 rrecover vga fd096 lp rfd0 rfd196ds18 rroot xct0 fd096ds15 lp0 rfd0135ds18 rfd196ds9 rswap fd096ds18 lp0f rfd0135ds9 rhd00 ru ./dev/dsk: ./dev/rdsk: ./dev/rmt: ./etc: badtrk dkinit haltsys masterboot mnttab utmp default emulator inir mkdev mount divvy fdisk init mknod umount ./etc/default: boot ./mnt: ./tmp: ==== Ed.

Well ok. I went through the fine manuals several times before I found it. (I was almost ready to post...:-) I have another question in the same vein: Once the emergency boot floppy is made, how does one go about reloading a full system backup from the same floppy drive? In this case the boot device is the same as the backup device. Is a boot floppy no good if more than a fsck is required in an 'emergency'? (I'm running SCO Unix, but I suspect the procedure would be the same Unix or Xenix.) hank White Oak Software Inc.

: actually you will want to try the following for creating a bootable : floppy: : : "mkdev fd" : : read the man page for more info and restrictions ... It may be wise to build a system with only the disks and tape drive configured, then make and test your boot floppies. Afterwards you can add the 69,000 /dev entried required to activate your favorite toys. You don't need pty's on your boot disc, and such files may overflow the floppy disc.
