Xecuter FlashBIOS v3.0.3

Use the form below to update the BIOS of your modchip via webserver. WARNING! It will use the file you upload to replace the contents of the currently selected 1MB bank (For X2 mods it will simply start flashing from the beginning of bank 1 - your bios needs to ideally be 512k (2 x 256k) - that way if you mess up you can switch to bank 2 and get back to the FlashBIOS). Make sure you have read all the documentation before flashing.
The file uploaded was not 262144, 524288 or 1048576 bytes. Refusing to flash.
