Asus 48X Firmware

I need this firmware in hex version,Everywhere in internet this bios is only in bin version.Please help me??!?! If you have asus 48x you can read bios by mtkflash software.You can download it from here : http://www.cdrinfo.pl/cdr/porady/liteon_oc/Mtkflash148.zip.
Thank you for help!!!

What’s the difference between hex and bin? The extension?
