I think it would be good to add instructions on creating disk.img.
Also, when I ran this (64-bit ubuntu) I get:
qemu-system-i386 -serial stdio -bios ~/u/b/qemu-x86/u-boot.rom -hda
disk.img -cdrom /vid/software/win/winxp.iso -smp 2 -m 512
WARNING: Image format was not specified for 'disk.img' and probing guessed raw.
Automatically detecting the format is dangerous for raw
images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
