As a matter of fact I had a reboot problem with the board which was heat related under windows9x, as well as windows 3.x when I first bought the board. When ambient temperature was above 72 deg F (old brain cells) the machine would not "reboot" soft, hard, warm, it did not matter. I traced the problem to a single custom logic chip on the mother board which I could use a can of "freeze it" on and alleviate the problem. I had them, Gateway, and later Micronics, send me a replacement motherboard, but the results were exactly the same. This is not the same problem. An obvious difference is that during the reboot process the ATI Mach32 VGA board resets and does a characteristic "blink" on the screen with Red Blue and Green color bands during reset. When the earlier heat related problem was evident the reboot froze before this point. NOW the reboot is proceeding through this, and actually starting the reboot process, including reading initial boot code from the hard drive. Another difference is that under FreeBSD 3.4 it did not have this problem. If I/We can track and solve this problem, other 486 owners, like Blaz may be helped. (BTW we've "GOT" to keep these old 486 systems running because I really LOVE it when I get to tell a colleague how well an old 486 of mine with 32 meg of RAM is performing some gritty network task that they just told me their NT based x00MHZ PIII with X-Hundred Meg of RAM can't handle. It makes for a nice comparison!!) Cla. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
