Grub size problem

[Cal <tech liderbug com>]

I'm trying to create a boot floppy to switch between hda and sda.  But it
won't fit on a floppy and it seems to be the same problem when I try to
put the boot loader on the HD also because when I reboot I get:
GRUB GRUB GRUB (and it hangs).

Advice pls......
Tks
