Hello, I´m planning to buy a used Lenovo Thinkpad W510. Are those BIOSes from Lenovo also locked, do they hide options from user ? Are those BIOSes also RSA signed ? I asked because my HP 255 have Insyde BIOS with very restricted options, not able to access AHCI and so on. If Lenovo has the same sh*t I will not go to buy it. Thanks for help. Greets.
