The 21064 has 43-bit virtual and 34-bit physical addresses, while the 21164 has 43-bit virtual and 40-bit physical. The Alpha architecture actually supports using up to 64-bit virtual addresses but I don't think any of the current implementations actually implement that. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
