You only have to do this twice, then MS-DOS is installed. Remember it's control+alt+2 to get to the qemu console to change the floppy to dos622_2.img, then control+alt+1 to get back to the display to hit enter. Let it have the whole disk, you just hit enter a few times, then qemu will reboot, then it will format the disk & then prompt for disk two.
On the first boot, MS-DOS will partition the disk & slap down a MBR. Qemu-system-i386 -hda msdos.disk -m 64 -L. So there is no point in letting qemu grab 128mb of ram. MS-DOS himem.sys will only see a maximum of 64MB of ram. Also the installation, and all files will run on 8088/8086 or higher so you don't have to worry about any cpu flags. MS-DOS uses the BIOS for all IO so the ISA/PCI thing doesn't matter. I'm going to create a 2GB one, so the syntax is: The first step is to create a hard disk image.
