Make sure u do not have a 1.6b check for hynix ram..
to install this on a 1.6b you need your switches set to off,on,off,off to boot up the flashbios...then and this is important
whilst it is still switched on change the switches to on,on,off,off and then flash the x3 bios to this location.
failure to do this will overwrite your only working flashbios on a 1.6b.
Once you have a bios with CFL then you can enter ConFig Live and reflash your backup bios with 3.03 flashbios.
for a 1.6 do the same but start with on,on,off,off and switch to off,on,off,off before you flash. At least with a 1.6 u still have backup bios but still better to overwrite the 3.03 flashbios as its useless to a 1.6
