Thank you so much :) ! -
Do I just copy the entire contents of device.hints to loader.conf.local?
My problem is I can't boot unless I comment out:
#hint.uart.0.at="isa" #hint.uart.0.port="0x3F8" #hint.uart.0.flags="0x10" #hint.uart.0.irq="4" #hint.uart.1.at="isa" #hint.uart.1.port="0x2F8" #hint.uart.1.irq="3" -

You can set device hints in loader.conf.local and they will be kept.
I read this thread and something is not quiet clear to me: setting device hints in loader.conf.local - OK, but how deactivate existent hints (in /boot/device.hints) in loader.conf local? In my opinion the deactivation has to be done every time a update/upgrade is taking place.
-
Indeed, I can't see any way to unset a hint. But you could set it to something else. Or in this case if it won't boot with the uarts setup at the standard locations you could disable them entirely:
hint.uart.0.disabled="1" hint.uart.1.disabled="1"Steve

This is what I do to get it to boot initially and then edit the device.hints for future reboots but it doesn't stick through upgrades/updates.
Here is the link I found to help me to get it to bootup the first time. It was a head scratcher for a little while:

I was just checking to see if there was a way to not have to do this through upgrades. I'm not even sure what those are for lol
-
Ok, well I would try:
hint.uart.0.at="0" hint.uart.1.at="0"But setting it disabled there is probably just as good. There is probably some resource conflict caused by the serial ports on the device for some reason.

Yes these work for first boot if you interrupt no problem, they just don't persist without commenting out the above lines and those don't persist through updates/upgrades.
Just a pain because this is setup in a closet without a keyboard and monitor, so there is no way to update/upgrade without taking it out of the closet etc...
-
Right which is why you need to put them in /boot/loader.conf.local which is maintained across an upgrade.
-
Ohhh okay, took me a while to get there lol
So just add:
hint.uart.0.disabled="1" hint.uart.1.disabled="1"to the loader.conf.local and all should be good?
-
You'll have to test to know if that works. Be sure to have console access in case it doesn't boot!

Would you please so friendly and take a minute on top to this file called /boot/loader.conf.local please.
If I write something in, like the thread opener his line,
and I have several different line to put in for several things
and I want comment this line for what they are standing,
how to do this without problems? as an example:set CPU Frequent high up to 1400 MHz hint.p4tcc.0.disabled=1 hint.acpi_throttle.0.disabled=1 hint.acpi_perf.0.disabled=1 -
The octothorpe
#indicates a comment so you could do:# CPU Power and Frequency settings set CPU Frequent high up to 1400 MHz hint.p4tcc.0.disabled=1 hint.acpi_throttle.0.disabled=1 hint.acpi_perf.0.disabled=1 -
@stephenw10
Thank you!Here is none active and;
# set CPU Frequent high up to 1400 MHz #hint.p4tcc.0.disabled=1 #hint.acpi_throttle.0.disabled=1 #hint.acpi_perf.0.disabled=1here are all active, is this rigt?
# set CPU Frequent high up to 1400 MHz hint.p4tcc.0.disabled=1 hint.acpi_throttle.0.disabled=1 hint.acpi_perf.0.disabled=1I will try out this for my new installation on CP Engines APU to tune the CPU is able going something between
1000Mhz and 1400Mhz against default 600Mhz to 1000Mhz. -
That's correct.

Thank you very much for that information.
