full.bin состоит из нескольких кусков
смещения в файле
0-0x400 - хз какие то данные
0x400-0x4300 - нужно загрузить по адресу 0xC000
0x4300 - 0x43F8 - вроде как загрузчик? нижний адрес должен лежать в 0xFFFF (таблица прерываний) только что то там непонятки какие то с таблицей
я просто сребейзил прошивку по адресу 0xBC00 (0xC000-0x400), и абсолютные смещения стали валидными
