AMD implemented Intel MPSPEC 1.4 for SMP and it is closer to compliance than most Intel / serverworks systems. There is no magic required. I have a thunder K7 for my desktop with dual 1.2GHz AthlonMP's. All 4.x+ releases will boot on it. The only gotcha is that the older releases dont recognize the 766 IDE controller and run in biosdma mode instead of UDMA66/100. http://people.freebsd.org/~peter/thunderk7.txt I asked the Tyan people about the special power connector.. That's there solely for the AGPPro support. Other motherboards that have AGPPro have a second power connector. The base system uses nowhere near the power that the 460W power supplies are capable of, unless you start using the 200Watt+ double height AGPPro slot with the extra fingers for power feeds.
