Allocation of major number and minor number linux

HI
1.How do i allocate major mumber and minor numbers in linux 2.6.8 version.
Any idea.

2. Can we allocate Major numbers and minor numbers Dynamically?

If you're up to the stage of being able to write Linux device drivers, would you be
a) asking such questions.
b) be incapable of reading the relevant HOWTO to find out.
