I did it for the first time two days ago with the “binflash” that everybody seems to use. It should be found in any of the firmware threads. On that page there is instructions on how to flash the drive.
Basically, you DL the binflash, which is in fact called necflash.exe. Then, go to start > run and type “cmd”, then enter. That brings up your dos box. Now navigate to the directory that necflash.exe is in. We’ll assume you put it in c:\ along with the new firmware you want to install. Type:
necflash -scan <enter>
That brings up the drives you can do. In my case my Nec drive was e: (in the binflash directinos they call theirs 1.0.0).
Now, backup your old firmware with:
necflash -dump c:\oldfirmware.bin e:
Now, to flash it with the new firmware:
necflash -flash c:
Then you can run necflash -scan again and confirm that it was dumped properly.
I used the 2.27 + last night, and it automatically set the permanent booktype for SL, so you won’t need to bother changing that.
