Redfox ez3540 bios repair

hello, i have a desktop, its redfox ez3450-185iw, the motherboard marking is redfox havendale_hs_75mmx75mm. but i think the real board manufacturer is soyo, it has sticker of sy-h55t v21, and i think thats the correct board model. the board has no display but has all the voltages. i dig the web to find the bios but no luck. the board has only 1 eeprom(16mbits/2mb, winbond w25q16bvsig). im hoping that modifying the bios bin or fixing it will solve the problem. thank you.
