Phew... Yet another totally revamped BIOS option. Took me some time to sort this one out actually. Why? Well, because I was wrong all along!
Well, not completely wrong. The recommendation for the Video RAM Cacheable BIOS feature remains disabled but my earlier reasons for that recommendation were completely and utterly wrong! Sorry about that, everyone!
It was not easy to re-examine a staunchly-held belief. And so, I spent a lot of time double-checking my information. Only after much research did I rewrite the entire topic.
So, please check this newly corrected BOG topic on Video RAM Cacheable."
