I've had no problems with it at all. 440FX is the most popular PCI chipset for PP motherboard. I do not know its nickname either. I ordered two MBs with this chipset: one is Tyan S1662 and another is ASUS P6NP5 (dual CPU is P65UP5). FreeBSD 2.2-Alpha crashes on Tyan S1662 quite often on NFS Tx. The ASUS has not come in yet. The trade off is CPU power with I/O power. Pentinum Pro gives 50% CPU power than Pentinum, but 440FX has 25% less memory bandwith than Triton-II. Also, I experienced that PP has slow network I/O than Pentinum. Some more performance comparsion willbe found on: ftp://george.lbl.gov/pub/ccs/performance.ps (p6-7 for P<-->PP). It will be updated whenever the new board/machines come in. -Jin
