Lets
start
this with
an unmodded
xbox.
It basically
works
like this.
It turns
on, plays
that little
flubber
animation,
displays
the xbox
logo,
and then
looks
for a
disc in
the dvd
drive.
If the
disc meets
certain
criteria(digital
signatures
and media
flags
mainly)
it then
executes
default.xbe
off of
the root
of the
disc.
If there
is no
disc in
the drive,
the xbox
then boots
xboxdash.xbe(the
xbox dashboard)
off of
it's hard
drive.
This is
all done
by the
xbox BIOS.
Some
very crafty
people
managed
to obtain
this BIOS
from the
xbox and
modify
it. The
base thing
they've
done is
to remove
the requirements
for digitally
signed
software,
and also
remove
the requirements
for special
media
flags
for discs
put into
the dvd
drive.
This new
BIOS is
then put
onto a
flash
rom of
some sort
and wired
into the
xbox.
THe xbox
powers
up and
then executes
this new
bios instead.
The new
BIOS does
the exact
same thing
as the
original,
minus
the checks
for digital
signatures
and media
flags.
At this
point,
you can
then run
unmodded
code.
The first
thing
you'll
likely
run is
the Evolution-X
dashboard.
There
are many
tutorials
on how
to set
it up,
install
it on
your xbox,
etc.
