- You would have been correct on these IF the Trio64 chip used on the CV64
- could do 24 bit, but it can only do 32 bit with 8 bits unused.
- While this has no effect on the amount of needed DRAM (not VRAM) for
- 800x600 and 1024x768, it renders 1280x1024 impossible as you'd need 5 MB
- for 1280x1024x32 and the chip can handle only 4 MB.
- For details have a look into the databook of the S3 Trio64 (aka 86c764).

- Ciao, Klaus.
