This search is for 32 -bit Windows7 but BIOS is OS independent
This search shows both BIOS updates. I suggest the earliest one since that is what is shown on the product page. If that doesn't resolve the BSOD, then you might consider the other BIOS update. I read both descriptions and can't make a determination of the difference other than the L500 Pro is listed 1st on the 05/30/2011 2.10-WIN version.
The how-to update BIOS page is ok: How to update the BIOS on Toshiba notebooks
