So Channel9 has decided to broadcast Serenity at 8:30 on Saturday nights? What has it been? 7 years? How long will it last?

Dr. Quinn meets the new Battlestar? only 7 years too late.

I guess I could care if CH9 was more than a casino holding company.

Why do companies bother?

What country is this bird from?When you buy products from many IT companies you usually have to register. This will include telling them stuff like you email address and usually what country you are in. Often they require a lot more in the name of “serving you better”, right.

Do they ever actually use this information in a way that in beneficial to you? I don’t think so.

The number of dim entities that keep offering me cheap or free admission to an industry sponsored conference, … somewhere in the US. Now they know I’m in Australia. They required me to tell them that.

Worse than the geographic stupidity is the timezone cluelessness. Its even cheaper to run a “webinar” these days. Yay team, interact with our best engineers (as opposed to the ones who got pushed into marketing?). Again, no good sending an invite to me for 9am PST (Pacific standard time)! You know I’m at UTC+10, because you asked for it when I created a login! Extra insult is that webinars are not archived so that I can watch the one that occurred while I was sleeping/at work.

Building kqemu

qemu is enough to run tinycore without acceleration, but more is better right?

Get the source: kqemu-1.4.0pre1.tar.gz

$ tar zxf ../Downloads/kqemu-1.4.0pre1.tar.gz
$ cd kqemu-1.4.0.pre1

Edit Makefile.winnt, change




then apply the patch from here:

$ patch -p0 ../../Downloads/kqemu-mingw.diff
patching file `common/Makefile'
patching file `common/genmon.c'
patching file `common/i386/monitor-win32.ld'
patching file `common/i386/monitor_asm.S'
patching file `common/i386/nexus_asm.S'
patching file `common/kqemu_int.h'
Hunk #1 succeeded at 1057 (offset -6 lines).
patching file `common/x86_64/monitor-win32.ld'
patching file `common/x86_64/monitor_asm.S'
$ make -f Makefile.winnt
$ cp kqemu.sys kqemu.inf /c/apps/qemu-0.10.5

Now you need to do some surgery on kqemu.sys. Using the guide from here.

  • [DefaultInstall.NT] –> [DefaultInstall]
  • [DefaultInstall.NT.Services] –> [DefaultInstall.Services]
  • [Uninstall.NT] –> [Uninstall]
  • [Uninstall.NT.Services] –> [Uninstall.Services]

Then right click on kqemu.inf -> install

Hand over UAC permission, then start an Administrator command shell, cd to the installation directory and:

c:appsqemu-0.10.5>net start kqemu

The KQEMU virtualisation module for QEMU service was started successfully.

Now when you start qemu, it goes faster! yay.

$ qemu -cdrom /c/Users/dpinson/Downloads/tinycore_2.2.iso -hda tinycore.img -m256 -boot d

Building qemu for a change

I’ve played with qemu on and off for as long as I can remember (and I remember struggling with Bochs on DEC OSF/1). These days life is Vista orientated for work reasons and by and by I’ve ended up with win32 as my main development environment, even when I work on GTK+ code (the beauty of cross platform libraries I guess).

Nowadays we are blessed with lots of good virtualisation software (VirtualPC, VMWare, VirtualBox). While I have a regular rotation of VirtualBox setups, I thought I could see how well qemu was going, but it seems that the win32 binaries are a bit on the stale side (0.9.0 vs 0.10.6). So lets try to build it under mingw/msys….


Download and install zlib.

$ tar zxf ../Downloads/zlib-1.2.3.tar.gz
$ cd zlib-1.2.3
$ make -f win32/Makefile.gcc
$ cp zlib.h zconf.h /usr/include
$ cp libz.a /usr/lib

Download and install SDL

$ tar zxf ../Downloads/SDL-1.2.13.tar.gz
$ cd SDL-1.2.13
$ ./configure --prefix=/usr
$ make

Which only gets to:

windres ./src/main/win32/version.rc build/version.o
/bin/sh ./libtool --mode=link gcc -o build/ build/SDL.lo build/SDL_error.lo build/SDL_fatal.lo build/SDL_audio.lo build/SDL_audiocvt.lo build/SDL_audiodev.lo build/SDL_mixer.lo build/SDL_mixer_MMX.lo build/SDL_mixer_MMX_VC.lo build/SDL_mixer_m68k.lo build/SDL_wave.lo build/SDL_cdrom.lo build/SDL_cpuinfo.lo build/SDL_active.lo build/SDL_events.lo build/SDL_expose.lo build/SDL_keyboard.lo build/SDL_mouse.lo build/SDL_quit.lo build/SDL_resize.lo build/SDL_rwops.lo build/SDL_getenv.lo build/SDL_iconv.lo build/SDL_malloc.lo build/SDL_qsort.lo build/SDL_stdlib.lo build/SDL_string.lo build/SDL_thread.lo build/SDL_timer.lo build/SDL_RLEaccel.lo build/SDL_blit.lo build/SDL_blit_0.lo build/SDL_blit_1.lo build/SDL_blit_A.lo build/SDL_blit_N.lo build/SDL_bmp.lo build/SDL_cursor.lo build/SDL_gamma.lo build/SDL_pixels.lo build/SDL_stretch.lo build/SDL_surface.lo build/SDL_video.lo build/SDL_yuv.lo build/SDL_yuv_mmx.lo build/SDL_yuv_sw.lo build/SDL_joystick.lo build/SDL_nullevents.lo build/SDL_nullmouse.lo build/SDL_nullvideo.lo build/SDL_diskaudio.lo build/SDL_dummyaudio.lo build/SDL_sysevents.lo build/SDL_sysmouse.lo build/SDL_syswm.lo build/SDL_wingl.lo build/SDL_dibevents.lo build/SDL_dibvideo.lo build/SDL_dibaudio.lo build/SDL_mmjoystick.lo build/SDL_syscdrom.lo build/SDL_sysmutex.lo build/SDL_syssem.lo build/SDL_systhread.lo build/SDL_syscond.lo build/SDL_systimer.lo build/SDL_sysloadso.lo build/version.o  -lm -luser32 -lgdi32 -lwinmm -no-undefined -rpath /usr/lib -release 1.2 -version-info 11:2:11
libtool: link: cannot build libtool library `build/' from non-libtool objects on this host: build/version.o
make: *** [build/] Error 1

Then we need to use the magic pointed to here:

$ ./libtool --tag=RC --mode=compile windres src/main/win32/version.rc -o build/version.o
then edit Makefile and change “$(objects)/version.o” to “$(objects)/version.lo”

and finally we can do:

$ make
$ make install

Now for qemu

$ tar zxf ../Downloads/qemu-0.10.5.tar.gz
$ cd qemu-0.10.5
$ ./configure --prefix=/c/apps/qemu-0.10.5 --disable-kvm
Error: zlib check failed
Make sure to have the zlib libs and headers installed.

I couldn’t resolve this in a nice way… I just edited the configure file to add OS_FLAGS to the MINGW32 section:

OS_CFLAGS="-I/usr/include -L/usr/lib"
if [ "$cpu" = "i386" ] ; then


$ ./configure --prefix=/c/apps/qemu-0.10.5 --disable-kvm
$ make
c:/apps/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -lz
collect2: ld returned 1 exit status
make: *** [qemu-img.exe] Error 1

It seems that zlib still isn’t found. So to be expedient, add it to the Makefile:





and we are away…

$ make
$ make install

Almost there…

$ ./qemu-img.exe create -f qcow2 tinycore.img 1G
Formatting ‘tinycore.img’, fmt=qcow2, size=1048576 kB

$ qemu -cdrom /c/Users/dpinson/Downloads/tinycore_2.2.iso -hda tinycore.img -m 256 -boot d
Could not open ‘\.kqemu’ – QEMU acceleration layer not activated: 2

Next time we will build kqemu.
