The Be FAQs
BeOS for Power Mac

 

My video card (or built-in video) supports 16-bit color ("Thousands") but not 32-bit color ("Millions") on the Mac OS side. Can I use something besides 8-bit color under the BeOS?

Generally speaking, color depth on screen is limited primarily by the amount of video memory your graphics system has (there are exceptions to this). Larger screens require more memory, as do higher bit depths.

If you have video hardware that could support 16-bit color, and you have a multisync monitor, you can try reducing the screen size. This will reduce the amount of memory used by the size of the screen, possibly giving you enough extra memory to increase the color depth.

For example, if your monitor runs at 1024 by 768 pixels in 16-bit color under the Mac OS (and there isn't enough video memory to run in 32-bit color), under the BeOS you will only get 8-bit color. Reducing your BeOS screen resolution to 800 by 600 pixels in the Screen preferences application may free up enough video RAM to go to 32-bit color (it works on my Power Center 132).

Another alternative would be to buy more video memory for your computer, if it supports increasing that memory. VRAM is fairly cheap, since you will only need another megabyte or two...
