[...] FYI, the only time that I have actually seen a random rebooting problem with FreeBSD involved RAM. You can test to see if that is the case using the program available here: http://www.teresaudio.com/memtest86/ Certain Athlon-compatible motherboards are very poorly made, which may be the cause. COuld you post the manufacturer, model, and preferably the chipset used (eg VIAKT133, AMD750, etc). There are certain problems with VIA chipsets and certain motherboards which may possibly be a cause. Some manufacturers somewhat consistantly produce poor boards, such as PCChips (and their 50 or so other names, noteable ESC and Elitegroup). It may possibly be an overheating CPU, but this is quite unlikely considering that Athlons generally just lock up rather than rebooting when they overheat, and that they can get *very* hot before malfunctioning. If the system has a flimsy heatsink or poor contact between the heatsink and chip, such as with cheap paste or a thermal pad, it might be worth spending a few seconds checking out. I use the same SCSI card that your system has, so I know that it works quite well. I have heard of some problems in newsgroups about using the 64-bit version in a 32-bit PCI slot. I doubt it is the drives, too. As you said, you replaced tham, and IBM's SCSI drives are very well made. Sorry I don't have anything specific, but I hope these help a bit if you haven't already considered them. There's always the classic "update the firmware on everything" response that you have probably taken care of as well. _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
