No, I said a cold reboot. That's the term for a reboot which runs the entire POST, counts memory, etc. The screen looks identical to a cold start or cold boot. We all know what the warm reboot means -- that's when many parts of the POST are skipped. Windows uses a cold reboot, for example, when you click "Restart" on the Shutdown menu. FreeBSD does a warm reboot using the reboot command. The warm reboot may save thirty to sixty seconds over the cold reboot. A warm reboot typically skips the memory check and does a cursory check of hard drive parameters, etc. to save time. If you use a PC DOCTOR disk and tell it to reboot, it will do a cold reboot. When you flash your BIOS from DOS, it will usually do a cold reboot when it exits. When you save changes and reboot from the BIOS setup screen, it will do a cold reboot. Many other examples are possible. What I tried to explain is that this PC crashes on the subsequent boot if a warm reboot is performed by FreeBSD. But if I could perform a cold reboot every time, this would solve the issue. A cold reboot is not the act of "shutting the power off and turning it back on." That is called a power cycle and it is obviously manual. A cold reboot is done by a special software command. > > Another small guess - are you looking for 'shutdown -r now' by > any chance?

The revelation is at hand.
