On the i386, living with the misalignment is probably the best solution, unfortunately. The only alternatives I can think of are: - bcopy the packet up by 2 bytes after reception to align the payload, or - disable PCI-X mode on the bus Both of those would probably be worse. > Do you need any other experiments done?

I agree with you about the noise. I think I'd rather spend the day in a room with a swarm of hornets than with the Dell 2650. When I was working with that machine I wore a pair of industrial-strength ear-protecting headphones, and my ears were still buzzing at the end of the day. John -- John Polstra John D.
