+Floppy disks and network not working on NT 3.1 on Qemu 1.2 rc1
+
+When I try to put Floppy IMG/IMA/VFD images on NT 3.1 when it is running on Qemu 1.2 rc, they are not recognized and the network is not working even though I set it correctly (especially the AMD PCnet adapter)
+Here's some screenshot of the floppy error:

+Thanks for testing qemu 1.2-rc!
+
+Can you confirm that both floppy and AMD PCnet worked in QEMU 1.1?
+
+If so, could you please try running git-bisect(1) to identify which
+commit introduced the breakage?
+
+$ git clone git://git.qemu.org/qemu.git
+$ cd qemu
+$ git bisect start v1.2-rc1 v1.1.0
+
+For more info on git-bisect(1):

+they worked in Qemu 1.1 and also in the previous versions and, by the way, I can't compile, I used a third party Win32 build of Qemu 1.2 rc1. :(

+Have you tried any other guest operating systems? If there is a more
+readily available guest OS that shows the same bug it would allow
+others to reproduce and debug this.

+it does not happen on NT 3.5, 3.51 or 4.0, only on 3.1.
+
+Found someone who had a copy of NT 3.1 handy and he bisected it to:

+ fdc: fix interrupt handling
+
+ If you call the SENSE INTERRUPT STATUS command while there is no interrupt
+ waiting you get as result unknown command.
+
+ Fixed status0 register handling for read/write/format commands.

+
+nice :) but what about the network?
+
+It appears that the fdc issue were addressed in this patch series:
+
+ http://thread.gmane.org/gmane.comp.emulators.qemu/168836
+
+Unfortunately the URL from comment #7 is dead nowadays ... has this fix been committed to the QEMU repository?
+
+The floppy fix appears to be commit 34abf9a7 (contained in qemu 1.3).
+
+I don't think anyone ever looked into the networking problem.
