Yes, indeed.  The current driver is still on 2000/XP because I only have
the DDK for that version of Windows right now.
I haven't evaluate the WDK that's used for Vista yet.

I'm still trying to figure out how to support Vista in the future because 
it has a quite different architecture for "native" Vista driver. IIRC it's the "KMDF" model.
"KMDF" is still a big question mark for me :-(. As for Windows 98. I'm not sure yet whether 
I will be able to "backport" the driver to support it or not. But, Vista support will surely 
become a priority in the future. Anyway, I have no Vista platform for testing for the moment.
I'm focusing on 2000/XP right now. Beside, I heard that there will be service pack for Vista 
in the near future. Maybe, it's better to wait for it before trying to do anything with Vista 
because sometimes a new improved version of the Kernel API function is coming down the road. 
As for the driver signing. I'm also thinking about it. But, IIRC there is a way to generate 
the "signing" related stuff just enough to make it capable to be loaded in Vista. 
I'm not sure but I guess it's in one of my OSR magazine sent a few months ago. 
I'll try digging up on them ;-).

This issue will need more testing to be solved because I have no problem at all 
doing it in two different motherboards. I successfully carry out the flashing 
even in motherboard that not officially supports windows-based flashing program.
I'm using the very early beta version of my program to flash a modified BIOS and it works 
flawlessly (It's a VIA693A motherboard).
