for all who wonder how they will OS'dev on their floppyless laptop/imac/pda/whatever, here is *one* solution ...
1. have GRUB tools installed on your host system (this should come with /usr/sbin/grub and the stage1, stage2, etc. files ... )
I had my own stage1, etc. files from an archive named grub-0.92-i386-pc.tar.gz
2. create an empty file of 1.44MB with
3. become super-user and
4. create looppoint/boot/grub and copy all the files under your reference /boot/grub there ...
5. umount the looppoint
6. create a 'fake-device.map' file in which you will tell
7. invoke '/usr/sbin/grub --device-map=fake-device.map'
8. once in the GRUB shell, issue the following commands:
and voil?! your grubfd.img should now be bootable under bochs or any other PC emulator 
let me know if it works for you ...
