Make a windows bootfloppy image. I always have a Windows 95 bootfloppy
image available to start off with. You can make this image by doing:
dd if=/dev/fd0 of=dos-floppy.img
if you have a bootable floppy available. Then loop-mount that image, by
doing:
mount -o loop dos-floppy.img /media/floppy
Now you can remove unnecessary files from /media/floppy and add your .exe
files. If you have a Windows 95 or Windows 98 bootfloppy that creates a
ramdisk, it may safe you some extra work when you have to unzip this
self-executable archive.
You don't actually need a floppy-drive or a floppy to boot this image. You
can use memdisk to boot from this image directly. Just add a grub or lilo
entry, and use memdisk as the kernel and your bootdisk image as the
initrd.
Kind regards,
