I just got a new k6/200 and tried setting the memory speed to Turbo, but about a half hour into the buildworld, it would crash... once corrupting five bytes in a file (`= "NO' with `^P^Q \xb7o' which is kinda wierd, two bytes were slid by one bit, another two had signle bit errors, and another one just didn't look at all similar to the original pattern... otherwise the system would run normally... right now I've put it back to fast (from Turbo)... but that was just under an hour ago... now to get the scsi bus interference out of my stereo system... (and it's only a fast system too) :( -- John-Mark Gurney Modem/FAX: +1 541 683 6954 Cu Networking P.O. Box 5693, 97405 Live in Peace, destroy Micro$oft, support free software, run FreeBSD
