floppy boot

[Gerd Knorr <kraxel@suse.de>]

  Hi,

Is there some way to boot vmx machines from a floppy image (or
iso image)?  With "boot=a" in the config file xm complains that
it doesn't know what 'a' is.  With "boot=fda" that isn't the
case, but the sdl window doesn't shows up.  With no boot= line
everything works fine up to the point where the bios tries to
boot the boot sector from the (still empty) virtual hard disk.

Any hints?
