only 256 colors!

I recently had to format my hard drive and reinstall everything again (Win98). I can only get 256 colors in the display settings. I looked to see what type of video card I have but I can't find one, I think it is apart of the motherboard. My question is how do I find out what kind of driver I need to get 16 or 32 bit color. I previously had these and had no problems in that area. I've got everything working great except the display settings. Thank you in advance.

If you don't seem to have a video card, then you're right, it's probably integrated. Rather than look for the chip itself just find out the motherboard's manufacturer (ASUS, Gigabyte etc) and the model. The manufacturer is certain to have the relevant drivers, which is exactly what you need.
