request Samsung R525 Notebook

Hi

Manufacturer: Samsung
Type: Laptop
Model: NP-R525-JT02DE
BIOS version: 02UF
BIOS Download Link: http://www.samsung.com/de/support/model/...adName=DR# ->firmware

Any chance to unlock hidden options in the bios?
The switchable graphics cause a lot of trouble with the old Samsung drivers and I'd like to switch off the onboard HD 4200.

thx
