nx9420: Need info about Bit-shift/LBA in BIOS

I just replaced HDD in my nx9420, and upgraded BIOS at the same time, from F17 to F1B.

I was looking though the new BIOS to see if I could find any changes, when I saw:

HDD Translation Mode: Bit-shift or LBA-assisted.

It's possible that it was available in the old BIOS, but I don't remember. But the thing is that it was set to Bit-shift, which makes me believe that it was like that in F17 as well. I understand that Bit-shift is used for very old HDD's.

I have installed Vista 5 times and XP once today (because of a unattend.xml that never worked and only gave me problems), so I really don't feel like doing it again.

So my question is, will the fact that I installed with Bit-shift enabled and switched to LBA afterwards affect performance?

 

Since they involve remapping, won't you have to reformat the disk? I'm not sure if Windows will even boot on a translation change. There should be no difference in performance.

 

no... changing that setting does not require you to format ... you only need the MBR from a LBA/bit shift to update yours and it will boot not problem

 

Thanks for the help!
I ended up installing once more (messed up the install...), so I guess there's no problem anymore.
