version 1.0 of xbox.
soldered xapt3r to motherboard.
Power up and I get 3 blue leds and one flash from red led.
All seems ok at that point.
Add smartxx3, dvd, hd, power, connect to tv...
and I get the WELCOME screen.
However, it says press A to flash bios. Nothing happens.
There is no way to leave the welcome screen.
Complete newbie, but I have searched and have not found this problem in any other post.
Any ideas would be appreciated.
