Sender: owner-questions@FreeBSD.ORG Precedence: bulk Alan The Nice motherboard that you have is not the Nicest - both back then and now. It is not fully EISA compliant - Nice or MCCI who made that board - now the owner of SuperMicro - took some shortcuts in that design. My advice: Get a new Pentium/PCI Triton motherboard made by a reputable company. or Be happy with what you have. efarris@www.surfusa.com --------------------------------------------------------------- Hi, I am about to upgrade my FBSD 2.0 system to 2.1 and am thinking about upgrading the hardware as well. Currently, I have a Intel 486DX2/66 in a NICE Mini EISA/VLB motherboard with 16 Meg of RAM (The chips are OKI M514100B-70SJ, so I am guessing they are 70ns). Questions: 1. What is the fastest chip I can plop into my ZIF socket with no other changes? 2. Can I just change the crystal to get a 50MHz system? If so, will my ATI GUP handle the faster bus? (There are no other VLB boards.) Is my memory (assuming it *is* 70ns) fast enough? 3. Does it make more sense to get a PCI mother board? In general, I would appreciate any suggestions for squeezing the last drop of performance out of this system. -----------------------------------------------------------------
