The installed chipset was a Cirrus Logic 5428. Not a bad video system, but it only had 512K of video memory. I really think that this is the weakest point of the system now, but it should do for a while. At least it can do 800x600 at 65K colors now, so it's tolerable. And the addition of the Pentium Overdrive chip made screen updates and redraws much faster than they were.
Video is fantastic now.
So I popped a 1.2GB hard drive in, and cloned the hard drive from the 250MB to the new one. Sounds simple, but not so. This worked fine once everything was set up properly. With the new hard drive and processor, the system definitely took on a new personality. Any swapping that had to be done seemed hundreds of times faster now.
