DVRFlash command line

I want to cross flash my Asus DRW-1608P2S into Pioneer DVR-110 and did a lot of research here.
I learned that buffalo’s 839 zip wpuld be a good option
The file contains:
RA154010.839
RA154110.839
UPGRADE.EXE

Since i don’t know upgrade exe’s command line parameters i planned to use DVRflash 2.2.
I understand that the commandline needs to look like this:
dvrflash -vff “drive:” “kernal” “firmware”
I think de firmware file is one of the above, but what is the “kernel” file and where would i find that?

In spite of my search I couldn’t find the answer to my question so my apologies if turns out to be somewhere. But any advice is greatly appreciated.

Never ever try this combination!
Even more not -ff if you don’t know what it does…

THX 4 the warning, but I already discovered that I coulddo it with just the exe. included in the patch.
