That might explain the problem I had with an Athlon 800 on Asus A7V. System would not run thru a complete "make buildworld" without core dump or kernel panic (think it was core dump). So I went BIOS-diving and reading the manual carefully about the fine details of each configurable parameter. Found one that defaulted off for Duron but on for Athlon where the description mentioned "off" disabled PCI 2.2 enhancements. "Off" cured my problems and the machine has been rock solid since December when it was built. Maybe that parameter or another mentioned "overlapping data transfer" as well. Have always attributed the problem to my old PCI cards. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
