it? It you cant directly, then how about booting from a floppy which
can then tell the system to goto external hd and load windows???

If your system does not have a BIOS option to boot from a USB or
Firewire drive then you won't be able to boot XP off of one. If the
drive is supported in the BIOS and can be accessed from DOS without a
driver then it _might_ be possible to make a boot diskette that
transfers control to the external disk but I've not heard of that ever
being done with XP.

In other words whether this can be done depends on the particular
capabilities of the machine that you are using, but in general you're
not going to find the capability to boot from USB or Firewire on any but
the newest hardware and you're going to find it on precious little of
that.

It was told in MS newsgroups by MS folks, boot device driver requires
special code to support switch from BIOS to the driver and to support paging
file/hiberfile operations, but neither USB nor IEEE1394 drivers contain it.
External SATA drive may work, though.
 
One more clarification: as long as an OS doesn't grab USB controller from
legacy-emulation BIOS, it will work. MSDOS is likely to boot, and possibly
Windows 95, but nothing more.

Bwah, you shouldn't have done that!

I thought I understood your previous explanation, now I
haven't got a clue what you were actually talking about.
Are you hinting at MS-DOS compatibility mode?
