I wish the process were simple enough to write a brief guide, but it is not. Further it is possible to ruin the board and make it unrepairable (I torched one while removing the BIOS chip).
The Flashrom software I mentioned can be found at https://www.flashrom.org/Flashrom. You need a bit of Linux knowledge to use it.
Flashrom can be used to to directly read and save your existing BIOS flash rom without any hardware modification BUT it will not write to the flash rom (hardware write protected I believe). So that is why you need a means of externally programming the flash rom. I did this with the Buspirate as an interface to Flashrom (just one way of doing it but any other way of directly programming can be used.
SInce you mentioned being a student, try the EE department lab there. They likely have the hardware to remove the flash rom, reprogram it and resolder. Just find a helpful person there. But beware, you can ruin the whole board during the removal and resoldering process. It is easier if it can be on-board programmed and just lifting the Vcc pin.
