I'm not sure how to get the MBR installed, but you could "dd" a block To be honest, when I want to play with dos I use one of the nice X86 emulators like "bochs" and run with a virtual disk (i.e. a file). It's much nicer than actually booting dos. You can set up the mtools programs to allow you to copy files in/out of the disks. bochs also lets you debug things like boot tracks and peripheral eproms, which can come in handy. I once did a uboot port to an x86 chip and did 95% of the work using bochs. bochs will boot almost anything, including linux. I have run linux inside bochs - it's not bad on a fast machine. qemu is also pretty snappy. -brad
