Downloaded with AIX 4.3.3.11, the 14 floppy boot images from
http://web.mit.edu/bootkit/rsaix/diag-2.4.3/
to a directory on my hard drive /floppyimages

Formatted some IBM format 1.44Mb Verbatim MF @HD Datalife floppy disks as
follows.
#format /dev/rfd0 which went okay, no errors.

then swapped into
#cd /floppyimages

then ran
#dd if=diag-1a of=/dev/fd0 bs=144k
which does not write diag-1a from /floppyimages to the floppy disk.

Somehow I don't think "bs=144k" (blocksize = 144 * 1024 bytes) is what you
want.
I would expect that the first block written consumes the entire diskette
leaving
no room for more data.

I'd leave that off. dd will only write out what it reads in, the floppy
images
should already be the correct size.

Many thanks for reply.
On 7012-250 from within #/floppyimage ran #dd if=diag-1a of=/dev/fd0
and after 16 minutes finally got on screen
2880+0 records in
2880+0 records out
On 7011-320 with diskette in, fd as first boot item in service mode and the
key in service mode it did not boot off diskette but off diagnostics on HD.
This machine previously booted off diskette 1a made on a Win machine.

Any ideas ?

Sorry - I'm not up to speed on the machines yet.

My shop is looking at moving from VMS to AIX. I did UNIX (AT&T System III) for a
couple of years back in the middle 80's, have played with Linux now and then,
have done some Tru64 SysAdmin work, have played with FreeBSD and NetBSD and have
a Solaris box at work that I have to deal with. So, I know some UN*X, but little
or nothing specific to AIX or the hardware it runs on.
