Tutorial
based
on this
post
of Arakon
on the
xboxhacker.net
forums.
This
tutorial
can be
used if
you can
to easily
switch
between
2 BIOS
versions.
For example
the Retail
BIOS &
Xtender1.1
BIOS or
Xtender1.0
&
Xtender1.1
, ...
This can
be usefull
if you
need both
the no-patch-hack
(Xtender1.1)
and no-reset-hack
(Xtender1.0).
For a
tutorial
how to
flash
&

a homebrew
mod ,

To make
sush a
switch
all you
need is
a 4mbit
EPROM
(27C040)
or FLASHROM
(29F040)
&
an ON/ON
switch.
Split
both BIOS'
in 256kbytes
parts
(with
windows
commander)
and take
from both
the LAST
file.
(call
them bios1.bin
and bios2.bin).
To put
both BIOS'
together
goto DOS
and type
:
"copy
/b bios1.bin
+ bios2.bin
dualbios.bin"
dualbios.bin
will now
be a 512kbytes
file.
Flash
your 4mbit
EP/FLASHROM
with that
file (more
info).
Now you
just have
to wire
the ON/ON
switch
&
EP/FLASHROM
this way
:
1st image
is for
EPROMs
, 2nd
is for
FLASHROMs
