- Isn't the VESA local bus standard limited to 40MHz for plug-in cards?
- (but hard-wired local-bus stuff on the motherboard can go up to 66MHz?)
- Wouln't this be a problem in a true 50MHz machine? In this case a DX280
- (if one were ever produced) would be the highest speed you could have without
- causing problems.
