Keep your BIOS A17; nothing to gain with version A18.

I'd planned to - at least until A18 comes out on the list of recommended updates when my laptop gets scanned on the driver updates page at Dell!

It's 2.5GHz & 8GB of RAM - so I don't plan to replace it for a year or so.  But I wanted to have all the updates that were applicable to be running on it.

Other than Downloading Directx Patch June 2010 and the Verde drivers for your video there are no extras or reason to update the bios unless you have an issue.
