Maybe the same problem exists with ARC.

No, the mini debugger can do that, too. Write milo.rom onto a DOS
floppy (use mcopy under Linux---NOT mount -t msdos!), hook up a serial
line to /dev/cua0 at 9600 baud, reboot system into MILO (e.g., using a
floppy boot), issue MILO command "bootopt 0", power cycle the machine,
you should get a nice prompt from the minidebugger. If so, do:
Then do a "romlist" to find an empty spot in the FLASH (or a spot that
you're willing to nuke), then do:
flash 200000 SEGMENT
where SEGMENT is the number of the first flash segment that you want
to overwrite. Finally, do a "bootopt N" in the minidebugger where is
128 if MILO is the first ROM image, 129 if MILO is the second image,
Of course, this is all from memory and has the potential to render
your machine unusable. In particular, do NOT touch segments 0-2 in
the flash ROM since that's where the minidebugger lives. If the
minidebugger goes south, you're in for real trouble (it's possible to
recover from that case still, but it's hairy).
