Can't create boot floppy with bootnet.img

If I run the installer using bootnet.img and NFS the installation UPGRADE
process runs fine until I get to the "Create Boot Floppy" screen. After
inserting a formatted floppy and pressing next, the installer refuses to
accept that a valid floppy disk has been supplied. I then select skip and
the installer continues and reboots the system. After the reboot I then
discover that the booted kernel from the MBR is not 2.4.2-2 but my
previous 2.2.17-14. 2.4.2 seems to be installed, but not configured.
I have used bootnet.img twice now on different systems and I get the same
problem. However, if I run the upgrade directly off the boot CD-ROM the
whole upgrade process works fine; the boot floppy is created and the 2.4.2
kernel is installed and configured in lilo.
Steps to Reproduce:
1. See description.
Actual Results: No boot floppy created and kernel not upgraded to 2.4.2.
Expected Results: Boot floppy created and kernel 2.4.2 installed and
configured by lilo.
To fix the effected machines, I have to reapply the kernel-2.4.2.rpm and
configure lilo to redo the MBR and then create a boot floppy with
Do you have an LS-120 drive in this machine?
No, both the machines I upgraded with bootnet.img just have standard 1.44Mb
floppy drives. We have very few LS-120 drives on our site. The upgrade process
works fine straight off the boot CD; created from the ISO images. Could the
problem be elsewhere, eg: a missing file after copying the distribution to a
single directory from the two ISO images.

Additional cases of not being able to make boot floppies during install
The blank floppy I used came straight out of a new box. The bootnet.img
installer would not touch it, but the boot CDROM installer was able to use the
same floppy disk fine.
If anyone wants me to try the bootnet.img on a third machine I can do this. If
so, are there any suggestions on how I could supply any more useful
information. I checked all the console screens (1 through 7) on the first two
upgrades with bootnet.img, but didn't notice any unusual error or warning
Sure, try it on a third machine. These aren't USB floppy drives, or anything
else out of the ordinary, are they? I just did an install on my test machine
using a bootnet.img and the installer make a boot disk just fine.
No, they are just normal internal floppy drives. I'll upgrade another machine
soon. I just need to determine a time I can upgrade machine when no other users
are working on it.
Putting in NEEDINFO state until you get a chance to test this out.
Well I have upgraded another two machines now with the bootnet.img and
everything proceeded fine without a problem. Strange because these two machines
are identical (and I mean exactly identical hardware wise) to the first two
that did not install correctly. The only difference was that I rebuilt the
RedHat NFS source directory off the CDROMs hoping that something may have gone
wrong the first time I did this.
ie. "cp -a /mnt/cdrom/RedHat /mirror/rh7.1" for both CDROMs
I have two more machines to go, so if anything happens with these I'll be back
with more info.
Thanks and Have Fun!!
Good. I'm glad things seem to be working out. I'm going to close the bug now
because the installer appears to be working. But please reopen this bug if you
see any more problems. Thanks for your report.
