The Xecuter3 has 2048Kb of available Flash ROM arranged in 8 banks of 256Kb each.
Thus the smallest BIOS image will be of no more than 256Kb so that it fits into just one of
these 8 banks.
There is also another 256Kb of Flash ROM which holds a backup copy of the FlashBIOS.
This is used when booting the XBox with the Power and Reset buttons pressed. As shown above,
the X3 logo will glow purple.
You can upgrade the 256K backup ROM but if you mess up, your backup ROM is gone.
Your choice (I didn't bother) but if you are so inclined, Quarkey42 includes
Backup BIOS Flashing instructions
on in the Xecuter X3 BIOS User Guide.
On the Pro switch, a switch is On and glows blue when
The two most common settings will be for banks 1234 or 5678 and thus the switches will be
| Bank ||Switch 1||Switch 2||Switch 3||Switch 4
Please see the section X3 External Switch in the
Unofficial X3 Guide & FAQ for
a list of all switch combinations. This has pictures of the old (original) X3 switch but the
nature of the bank selection has not changed.
Pro Switch with Bank 5678 Selected
In the images above the 4 LEDs on the right of the switch
were set to select the first 1024Kb of available Flash on the X3.
In the image on the right, banks 5678 have been selected (switches in position Off-ON-Off-Off) and the
X3 has been enabled (X3 logo glows blue).

Here's a screenshot (screen-photo?) of FlashBIOS 3.0.3 booting. If you get this, the
mod-chip is working fine and your soldering was ok :)
Information on your hardware is shown during BIOS boot and afterwards (CD & DVD).
The 5 options are pretty self-explanatory.
Network flashing allows you to use your browser to upload a BIOS file which typically has a
extension and a size of 1024Kb. Choosing Enable Network Flashing
activate the network interface (Ethernet port) so you need to make a network cable to your
switch|router|LAN is plugged in (at both ends!).
I had to use IE on a Windows box to upload the BIOS because Firefox
and Mozilla under Linux didn't like it. This is mentioned in the
which are a useful read.
I have always found that the Xbox fan is too noisy. Games console or not, if one is watching movies on it the background hum is very irritating. I wanted to replace the fan but found that it has custom-designed mounts for the Xbox chassis.
However it turns out there is enough space between the two caddies and the motherboard to insert a reduction resistor assembly from a Zalman
80mm quiet case fan.
I sourced mine in the UK from QuietPc ; note that the Zalman fan itself is quiet so that can always go into the spares box for another job!
In this detail around the Xbox fan, you will note that the fan header is a two-pin affair (black & red wires only) while the resistor assembly carries 3 wires. This is ok, the white one is used for speed sensing which the Xbox ignores (it simply ups the power to the fan to approximate a speed). The resistor assembly can either fit vertically, snugly against the fan or there is enough slack to bend it underneath the caddies when mounted.
Take care not to bend the resistor assembly too often because the resistor legs may come off the body of the resistor.
You may wish to consider wrapping the resistor and its legs in insulating tape if you are worried about the insulation creeping.
