When I say that I made the menu system work with Zitu's images, I
specifically mean it will recognize the disk image's file extension
that Zitu's program produces (which is *.dat, vs the usual .img and
.dsk extensions) and display those as menu choices.

The menu is only able to creating disk images with the mkqemuimage
util for now and while it wouldn't be a lot of work to add dd, I think
it would make the interface more confusing than it needs to be...

Perhaps a patch with a conditonal define for win32 targets to
mkqemuimage would be the better way to go...

Cheers,

[Qemu-devel] QEMU 0.6.1 ISO boot bug on Windows hosts?

[Garth Dahlstrom]

I just downloaded Ronald's QEMU 0.6.1 package.

Seems almost all my Knoppix based ISOs (Damn Small Linux, Feather
Linux, Knoppix 3.7 and KnoppMyth) crash as soon as the kernel starts
uncompressing...

I'm running on a 2x P3 800 - is there any SSE3 type optimization that
might be the cause or something?  Can anyone confirm this is a problem
for them on Win32?

Cheers,

-Garth

I only have dsl-0.8.1.1 and can boot it without problems (dsl 2 vga=normal
lang=fr dma) on win98/athlon1800. 
There is no special flags except for SDL ( CFLAGS='-O3 -pipe
-fomit-frame-pointer -march=i586', --enable-debug=no --disable-nasm
--enable-directx=no).
The only problem I have found is the keyboard (still AltGr), works for
freedos and win98 guest but not for dsl.

I did some further poking around... 
My P3 800 can run not boot linux past the isolinux prompt
(uncompressing kernel kills it, either in failsafe mode or as soon as
the video flips), this occurs if I boot from ISO or from a previously
working disk image.  Freedos boots and works okay, but can not be
closed.   When clicking on the window close X, neither Linux or
Freedos can close the QEMU window - the cpu shoots up to 100 and the
app can not close and must be forcefully terminated.

My 2 Pentium M laptops, which are about twice the clock speed, have no
problems booting or closing using the same install files (I copied
over the same crashing QEMU folder to one of them, and installed from
qemu-0.6.1.exe on the other and they both work).

There are a couple of differences I can think of...
The P3 800 is only XP SP1, this is an SMP machine (I'll try to boot it
with 1 CPU to see if that helps when I get back from work), and the
chip set only supports up to SSE1 I believe.

Both of my Laptops are XP SP2, single proc, and should do SSE2.

I have it running on a P3@730MHz (Coppermine Family 6 Model 8 Stepping 3)
with XP SP1 (5.1.2600 SP1 build 2600) 256M sdram, still with dsl-0.8.1.1,
boot ok, halt ok. Tried with the 0.6.1 and 0.6.1-fix, qemu -L .\bios -m
128 -locatime -user-net -enable-audio -cdrom I:\dsl.iso -boot d This let
me think that neither windows version nor specific extensions support is
an issue. The only thing I can see which is changed in the build process
is sdl.

Sorry to mention that, but I did not write this software. I found it
as an alternative to create files bigger than 2Gb quickly.

I'm not the owner/author in anyway, and we should make sure we don't
distribute this piece of software. We should instead point to it as
an alternative of mkqemuimage, or fix the latter as Fabrice pointed
out...
