ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods.
**Reset Key:** Hold down the key located at K00, commonly programmed as left control while plugging in the keyboard.
Windows:
1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
2. Place your keyboard into reset.
