This would be highly dependent on the machine. Maybe you can write more about the machine's make/model and what need changing.
Be sure to tell what vendor isn't helping you work this issue.

I'm experiencing the following problem:
Can't get full access to all BIOS parameters because they are grey on color and on that way it's absolutely impossible to make any changes.
Thanks for your cooperation in this matter.
