With the release of the A04 bios, the boot resolution fix is no longer needed. Plus with the side effects experienced by a few of us with installing AsTray, it would be wise to no longer recommend AsTray and instead the A04 bios from Dell.
It would also merit stating that previous users of AsTray should probably reinstall their graphics drivers to wipe the AsTray fix, and then upgrade bios to A04 (just in case). I haven't seen anyone having any side affects from not doing this, but it's probably best to recommend.
