Not that I can recall. As I stated earlier, I had to remove FBSD and install
Linux to be able to use this mailing list, but I did look through the logs
after the spontaneous reboots and found nothing that indicated what was

When I was using FBSD 6.1, it was always a spontaneous reboot, but the system
would usually freeze for a couple of seconds before the reboot occurred. I
found a notice in the errata on the FBSD website that sounded like it
addressed what could be causing this problem: "FreeBSD-EN-06:02.net", and I
applied the patch to 6.1 and rebuilt the kernel. I thought that this had
fixed the problem because I didn't get a spontaneous reboot after being on
the net for a short time. But, I was wrong because It did spontaneous reboot,
just not immediately after starting to use the net. So, that's when I moved
on to FBSD 6.2. After setting it up to dial up using KPPP, I was on the net
for maybe a half hour when it suddenly froze up. The computer was locked up.
I had to hard reboot using the power button. After that, I put linux back on
the system to seek help, since I didn't know what the problem was and I
coundn't use FBSD to seek help.

No. I'm new to FreeBSD, and KPPP was quicker and easier for me to get up and
going, plus I like to have the icon docked into the system tray when I'm

I configured KPPP with the info needed to dial up.

My computer originally came with an internal modem which was on COM1 under
windows. COM2 would have been the serial nipple on the back of the computer.
I removed the internal modem, and when I attached the external modem, I
assume the serial controller on the motherboard reassigned the external
nipple to COM1 and disabled COM2. The internal slot is empty, which I guess
is why FBSD throws the error message about it being disabled.

Well, using windows it was called advanced power management. Using linux, I
load the apm module via "modprobe apm". I think that my computer is too old
to be able to use ACPI. I think that came out a couple of years after my
computer was manufactured. I think I need the APM module, not the ACPI. I
haven't recompiled the FBSD kernel with APM enabled and ACPI disabled, but I
can. I remember reading somewhere, manual?, that they must not both be
enabled at the same time, but to use only one and disable the other.

OK. I will reinstall FBSD 6.2 and try to get the logs to you today if I have
time. If not today, then in a day or two for sure.
Thanks to all for the help and suggestions! I know I can get FBSD working on
this computer. Its a honey of an OS. I love how easy it is to encrypt the
swap partition, and the new kernel mode auditing features are a sweet
addition to a great system. FBSD had a bright future. I can't find anything
that I don't like, except that I can't use it (on the internet)...YET! ;)
