As shown on the Studio XPS 8100 drivers page, A05 is the final BIOS version. Dell would not update bios after that. Re: Is there anyway to update this BIOS to a newer version? no validated official Dell bios.  any update would be custom mod and can potentially brick the motherbooard.
Hello, I am using a Dell Studio XPS 8100 (rather old) and according to CPU-Z the motherboard is indicated as Dell Inc. Model 0T568R A00 and the BIOS Dell Inc. Version A05 Date 07/08/2010! Is there anyway to update this BIOS to a newer version? Or is this unit just too old to bother or is an update not even available anymore? Thanks. Zeisky
