I have a 8kta3+ here that has problems with some of the PC133 512Mb modules I got cheaply earlier this year, the problem was solved when I swithed of "page mode" in the BIOS, it then runs 100% stable even overclocked at 145Mhz and CAS2 which the modules shouldn't even support. > It is really hard for me to say if this is FreeBSD specific because I do > not tend to stress the system much when I have Linux running.

From what I can tell the newest Epox BIOS for the 8kta3 does *not* install the 686b fix when it doesn't detect a SBLive! sound card, nice but not good enough :/ -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
