QEMU on Windows QEMU is an emulator for various CPUs. It works on Linux, Windows, FreeBSD and Mac OS X. Windows version is in an alpha stage. Use a single hyphen for all options. 1. Install Please extract ziped file. When extracted, you are ready. 2. Starting a program There are two ways to start a program. 2.1 Using a batch file A file "qemu-win.bat" starts QEMU. Double click boots Linux on your desktop. When you use Command Prompt(MS-DOS Prompt), type qemu.exe -L . -hda linux.img An option "-hda" set hard disk image and an option "-L" set bios location. When a mouse cursor is missing, type Ctrl and Alt key together. Please use Alt and Tab on WindowsMe. To exit from Linux, press Ctrl-Alt-2 keys together then you will see (qemu) prompt. Then type quit. (qemu) quit 2.2 Using a shortcut Create a new shortcut of qemu.exe. Right click on the shortcut, append appropriate options like "C:\...\qemu.exe" -L . -hda linux.img at link to text field. Double click the shortcut. 3. Test There is a benchmark in linux.img. When Linux boots, type sh-2.05b# cd nbench sh-2.05b# ./nbench INTEGER INDEX and FLOATING-POINT INDEX are index to Pentium 90MHz. 4. x86_64 emulation A file "qemu-x86_64.bat" also boots linux on your desktop. It boots 32 bit and 64 bit OS. 5. Hard disk image A hard disk image file can be created by qemu-img.exe. To create a 10MB hard disk image file, type in command prompt: qemu-img.exe create harddisk.img 10M 6. Floppy and CD-ROM You can change a floppy and a CD-ROM image from QEMU Monitor. QEMU Monitor can be seen by pressing Ctrl, Alt, 2 key together. Pressing Ctrl, Alt, 1 key together returns to your guest OS. It needs to convert floppy and CD-ROM to image file to use it. For floppy, there are many converters. Please choose your favorite one. If you have CD-R writing software, you can use it. If you don't have it, you can use mkisofs command in cdrtools. To use them together, type: qemu.exe -L . -m 128 -boot a -fda floppy.img -hda harddisk.img -cdrom cdimage.iso -L : bios location -m : memory size (Mbyte) -boot : boot device floppy(a), hard disk(c), CD-ROM(d) -fda : floppy image -hda : hard disk image -cdrom : CD-ROM image When you want to change a floppy and CD-ROM image, type: (qemu) change fda filename.img or (qemu) change cdrom fdimage.iso 7. Uninstall Please delete the extracted folder. If you use an installer, the program uses a registry. 8. Notes Don't start two QEMU on one hard disk image. It will break the hard disk image. 9.
