I have been trying to update the bios on my new Samsung R610 Laptop for a while with no good result.
I have been trying with Vista 64-Bit and Win 7 RTM 64-Bit.
And now I uninstalled my Windows 7 64-bit and installed Vista 32-bit and now It went well! Nice and not nice!
If I purshace Windows Vista or Windows 7 64-bit in a store and then
as I did make a fresh install of the operating system.
And then I need to download a trial of Windows Vista 32-bit and wipe my new OS install before I can upgrade the bios and install a 64-bit OS again 
This is an 64-bit Office computer and needs an 32-bit Operating System to be bios updated…
…I say no more…

Samsung R610 + update bios http://bit.ly/2aueju
Lenovo state that you need a bootable cd with the new bios to upgrade if your running a 64bit OS. I guess this isn’t a specific Samsung problem.
But too bad that they didn’t offer another way of updating the BIOS, like lenovo.
Here at work we have hundreds of computers and that way will not work at all.
I hope all hardware vendors will support 64/bit bios updates in the future…
