I had a Dell dimension 1100 (nearly identical to the B110). I've never heard of tweaking Intel Integrated graphics. Honestly, it's not worth it for any level of intel IGPs.
That PC is not going to work for gaming, period. It's not even worth it to try to tweak the card, because any application that requires a stronger vid card would also need a stronger CPU than a Celeron or Pentium 4.
If you can find a cheap PCI vid card (not PCI-E or AGP) then you could give the graphics performance a slight boost, but don't expect anything great, and don't spend more than $15 since the CPU is extremely dated as well.
The last game I was able to play smoothly on that computer was either Star Wars: Jedi Knight - Dark Forces 2 or American McGee's Alice, and that was on low res, low quality, and I had a 2.3GHz Celeron D compared to your 2.0GHz.
I tried to install Age of Empires 3 on there, and it could run at low settings, until something graphics/physics intensive happened like a water battle, at which point the game became a slideshow.
In other words, it's too weak for anything modern. Anything old worth running will run fine with the graphics the way it is.
