QEMU on Windows QEMU is an emulator for various CPUs. It works on Linux ,Windows, FreeBSD and MaxOS X. Windows version is in an alpha stage. I checked it works on Windows2000SP4 and WindowsMe. Double hyphen "--" is no more needed. Please use a single hyphen for all options. 1. Install Please extract ziped file. When extracted, you are ready. 2. To start 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 Comand 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 cousor is missing, type Ctrl and Shift key together. Please use Alt and Tab on WindowsMe. To exit from Linux, click x mark of window's title bar. 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. Uninstall Plese delete the extracted folder. This program doesn't use the registry. 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. Notes Don't start two QEMU on one hard disk image. It will break the hard disk image. 8. License Please refer to QEMU home page and source codes.
