I just switched from AT&T UNIX 3.2.1 on Chinet to i386 2.0.2. Now, my 3.5 inch drives don't work at 1.44 megs (f03ht). They work ok at 720k. I can format them at 1.44 megs under i386, but they can't be read. I tried copying the pack.d/fd/Driver.o from the AT&T UNIX to see if that would fix it, but no luck. The strange thing is that Interactive ships 2.0.2 on 1.44 meg disks. This happens on all 386 machines at work, with various shipments of 2.0.2. Any ideas?? -randy -- Randy Suess randy@chinet.chi.il.us

Oops. I lied. Seems I got the wrong driver installed. Just
did it again, and the Driver.o out of AT&T UNIX fixes the
problem. pack.d/fd/Driver.o in AT&T UNIX is almost twice
as big as the one in i386.

Yeah, I tried using f13ht when I installed my second floppy drive, and had no luck. Then I discovered pg 104 of the 386/ix opserating sytem guide: f1q18dt - minor number 81 1.44 MB,entire 3.5 disk f1q18d - minor number 85 1.44 MB,omit boot track. subtract one from the above minor numbers to use as drive 0. Of course, if the special device files don't exist you'll have to use mknod to create them in both /dev/rdsk and /dev/dsk as char and block devices respectively. Now here's a question for the netlanders: I'm thinking of swapping my two drives, to make the 1.44 meg (in dos language) a:, and my 1.2 meg drive b:. Does anyone know how I can create a bootable 1.44 meg 386/ix floppy from my 1.2 meg distibution floppy? I tried dd unsuccessfully, but I could have specified some parameters incorrectly. -- Steve Izen: {sun,uunet}!cwjcc!skybridge!izen386!steve / Quote corner: or steve%izen386.uucp@skybridge.scl.cwru.edu / or izen@cwru.cwru.edu /-------------------------/ My second bike is a car. | The problem is that I *was* paying attention.

This also works for Microport, ESIX, etc...:
Just copy the first track, and then copy the rest. Under esix, copy the
first track using /dev/rdsk/f[01]t, and then copy the rest using
/dev/rdsk/f[01].
Or just copy all the disc but the 1st track using /dev/dsk/f[01], and then
install the boot /etc/fboot on the 1st track using /dev/dsk/f1t.

If you want to use dd, you can, but you have to use the "dt" devices in order to copy the boot track. The most useful thing to do though -- and the reason for posting this -- is to mount your bootable "install" floppy, and use dd to make an image copy so you can make new ones (the same size) later, but *also* to use mkdir /floppy # to keep the stuff -- change as appropriate dd if=/dev/rdsk/f0q15dt of=/floppy/IMAGEf0q15dt # or whatever mount /dev/dsk/f0q15d /mnt # mount it as /mnt cd /mnt # whir whir clank find . -print | cpio -pdlmv /floppy/files cd /floppy/files umount /dev/rdsk/f0q15d # or whatever -- "/mnt" might be OK Now you can look at the files that were on the boot floppy in the comfort of your own winchester :-)... In particular, INSTALL and INSTALL2 show how the hard disk is made bootable using dd from the boot track, and copying the necessary /etc/default files, etc., into place. You can also shave a few blocks off these scripts, which will mean that you can then install Unix a few more times before they becomre unuseable (or is that fixed in 2.0.2? I haven't checked). And of course, you can make a bootable disk with different programs on it... Lee -- Liam R.

I have a 1.44 MB boot floppy and want to produce a 1.2 MB boot floppy. I imagined this would work on a system with a 1.2 MB boot drive and a secondary 1.44 MB drive: format /dev/rdsk/f0q15dt dd if=/etc/fboot of=/dev/dsk/f0q15dt mkfs /dev/dsk/f0q15d 2370:144 1 32 labelit /dev/dsk/f0q15d instal flop mkdir /a /b mount /dev/dsk/f0q15d /a mount -r /dev/dsk/f1q18d /b cd /b find . -print | cpio -pdmuav /a This boot diskette will boot, display copyright messages, but then complains with: FD drv 0, blk 1581: Sector not found NOTICE: page read error on floppy disk 0, partition 2 So, what went wrong? -- Pim Zandbergen domain : pim@cti-software.nl CTI Software BV uucp : uunet!mcsun!hp4nl!ctisbv!pim Laan Copes van Cattenburch 70 phone : +31 70 3542302 2585 GD The Hague, The Netherlands fax : +31 70 3512837
