Modern BIOSes which support the BIOS Boot Spec. (BBS) will
let you *boot* a USB device.  It's emulated as an IDE device
by the BIOS.  DOS, however, will not "see" the other non-boot
USB devices without DOS USB drivers.  DOS will only see the
boot USB device because the BIOS is emulating it.  Also,
Windows 98/SE will *not* boot from a USB device.  Win98/SE
resets the USB controllers during startup of Windows which
causes a boot failure, i.e., no external USB install.  In fact,
I've failures with booting Linux from external USB devices too.

I would think the GRUB would allow you to boot DOS, and IIRC, that's
true.  But, I can't confirm since I've not used it for that.  It used
to be that Linux required the first partition on a hard disk to be a
swap partition.  That might interfere with booting DOS.  Some OSes won't
boot if the boot code isn't in the lower tracks of the disk.  IIRC,
DOS is one of those.

My recommendation if you want multiple systems on the same computer
is to install them on separate internal hard drives (or SSDs), then use
the BBS boot menu (usually F11 or somesuch...), to select a different
boot device at startup.  I would avoid USB, except to use it as a
replacement for a DOS floppy.
