Title: FreeBSD Boot Loader Hangs On Startup

---------------------------------------------------


Symptoms

The FreeBSD boot loader seems to hang at startup. The system will not respond and not boot.
Either nothing or one of the following may be printed on the system console:

|

or

boot: -D


Reason

The reasons for this are most probably

	Absence of a serial port on your mainboard
	The serial port on your mainboard is deactivated
	FreeBSD has a default value to use a non-existing serial port

Solution

The FreeBSD boot loader is by its nature very limited in its capabilities.

It has quiet enough intellence for reading boot blocks and starting a kernel, but it may stall if it is instructed to redirect it's output to a non-existing or disabled serial port.

So any of these solutions may apply:

	check your BIOS settings and enable the serial port(s)
	disable boot loader's serial console redirection (remove -D flag from /boot.config)
	check and correct to boot loader's compiled in default for the serial port if you have an usual setup
