Need Help- MSI WhiteBook BioS

Hi I tried searching the forum but did not find the answer under ;msi whitebook bios; or similar searches.
I also took a look at the msi faq but this was not answered.

the basic question is how do you upgrade bios on an MSI whitebook ?

Specifically i am considering picking up a 937-165641-005 (gx640 whitebook equivalent)
MSI Notebook Product Specifications

i am wondering if i need to, can i can flash using the gx640 bios from here MSI Global ? Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more

i see all sorts of warnings on msi pages about ;retail bios incompatible with whitebooks; and am wondering what is the technical feasibility here (does it actually flash successfully, never mind support or warranty)...

Do the bios not work, and just can;t be used to flash a whitebook ?
OR
Do the bios allow to flash but break your stuff if it's a whitebook?
Or
do the bios work fine and are just unsupported/void yer warranty by msi ?
or
something else?

Has anyone succesfully or unsuccessfully flashed the whitebook version of the gx640 ?

i am interested in the whitebook but fear if there are bios bugs or incompatibilities, and no way to flash bios, i could get stuck....


thanks
