I use nvflash442 while still in Windows!
You can use it from Windows cmd or create a shortcut to nvflash442.exe and put the parameters in it.
Get it here:

I made a file flash.bat containing:
nvflash442.exe -f %1 -p -u -2
@ echo .
@ pause

Then create a shortcut called Flashme with the following:
flash.bat BIOS.rom
Change BIOS.rom to whatever the ROM is. It must be a 8.3 file name.

Double click the shortcut to flash your card. When its finished it pauses so you can see the result. The window closes when you press a key.

I've done over 10 flashes so far in Windows and it seems trustworthy.
As it uses 100% CPU, close all programs and make sure your system has finished booting (I've seen long pauses in the boot process on some machines, even after the desktop appears).

I understand if you prefer DOS


To backup your current rom to saved.rom, use the following
nvflash442.exe -b saved.rom
