Rock Shox Magnesium fork bottoms out, help needed

I have a Rock Shox Magnesium fork with index adjusters, one on each side. I was told that it is a 1 and 1/4 inch steerer. The shock bottoms out. Even with the adjustment set to the stiffest setting, if I hit a small bump the top of the fork will hit against the tire? Is there any adjustment? What can I do? Do you know where I can buy a kit to rebuild the Rock Shox? I have included a view of the Rock Shox fork from the bottom, and top view showing the 2 adjusters. There isn't any obvious air fitting.
Thanks in advance for your help,
Uni

AFAIK, the mag forks were air-sprung/oil-damped. You need to increase the pressure in the air spring with a pump and a basketball-style inflation needle.

The dials are probably just to adjust the damping to tune the ride and do not affect the stiffness of the spring.

Thanks, the air fill apparently is covered by the center screw on the index adjuster, thanks to Jesus, I was able to find it.
How many pound(s) of air to put in? As soon as I remove the air needle, air comes out of the fill hole but a little pressure remains. I hope that is all I need. What do I need to do to increase the air pressure, as most of it is released before I can replace the fill screw?
Do I need to add oil? If so, please explain step by step.
Thanks in advance,
Uni
