Default Motherboard/PC not booting when no monitor connected ?!? (or switch connections ?)

Hello,

I switched my monitor from GT 520 graphics card to integrated graphics
RADEON 3300 chip/monitor connector.

So there are two hdmi connectors.

I noticed how the computer appeared to refuse to boot when there was no
monitor connected ?!?

Is that normal ? Is this a new kind of motherboard feature ?

(Perhaps it's a conspiracy People trying to boot "planks" with "beeps"
will think it's dead and buy a new one ! =))

Bye,
Skybuck.

Or maybe it's some kind of protection feature or even a bug in the
bios/motherboard.

Perhaps the second hdmi is not to be used if it's not the primary.

Perhaps it must first be configured in bios.

I think what I did was:

1. Set it up correctly.

2. Switch monitor connections.

3. The monitor or system didn't wanna boot or something.

4. After a reset it did boot ?!?

Something like that...

^ Me a bit confused about that.

Bye,
Skybuck.

Did you try both connectors? Are they really HDMI ? I thought was was
exclusively for TVs.....

There has been a feature in many motherboard BIOSes, for the last
couple of decades, which will deliberately halt the boot process and
wait for operator intervention if certain classes of hardware problems
are detected on boot. Bad or missing floppy drive, bad or missing
keyboard, bad or missing or unusable video adapter... etc.

I would guess that if you don't have the HDMI monitor plugged into
the connector, the video-card driver in the BIOS is failing to
detect any primary monitor, can't configure the video-card output in
the appropriate way, and is reporting a "video output failure"
condition.

The "halt boot on hardware error" behavior can almost always be
configured to some extent, via the BIOS setup screens or a separate
BIOS configuration program. For systems which normally run
unattended, it is common to set this option to "Continue to boot
despite any errors detected by the BIOS".

It's an Ignorance Detector. It selectively identifies computer users
who are (1) ignorant of decades of history of PC history, and (2)
don't bother to read the manual which came with their motherboard.

See the user manual.

Check for "Primary Graphics Adapter". Values are
[PCI], [Onboard], [PCI Express].

The setting controls the search for video adapters, and
may make a difference to whether the BIOS will display
on the screen or not.

While the monitor is connected to the video card, change
it to [Onboard], save and exit, then move the monitor
to the motherboard video connector and see what happens.

It shouldn't make a difference to booting, so I don't know
whether this is going to help or not.

*******

Another setting you would have been able to try, would be

"Halt On" [No Errors]

but your Asrock BIOS doesn't have that option. Perhaps
you could bypass a video problem, with a setting like that,
but it isn't available according to the manual. Take a
look through your BIOS screens, to see if it actually exists.

You probably right I mixed them up...

Sorry for confusion !

Assumption is the mother of all fok ups.

You assume my motherboard came with a bios manual.

As far as I know and can tell it did not.

Apperently this was a cost saving.

However perhaps online there will be a motherboard manual.

Why they simply don't put all that information in the bios itself is beyond
me.

Instead they waste precious space with nice looking boot pictures...

Bleh ! =D

Boot failures are rare for me, so my mind don't record settings like that !


I can vaguely remember seeing it... "halt on boot error" or so it's probably
called on old 80486.

So again another bad assumption of you !

I simply can't remember everything !

Bye,
Skybuck.

Good idea, I booted the pc into the bios, and there is an option called:

Boot Failure Guard [enabled]
Boot Failure Guard Count [3]

So this looks suspicious and might be the reason why it didn’t boot without
a monitor attached.

Skybuck.

Boot Failure Guard is there to help people who overclock.

My previous Asrock board had that option. If you press the
reset button, three times in a row, with a two second delay
between presses, it tells the computer that some setting
is preventing a normal boot. Such an option saves the user
from having to "Clear CMOS" to regain control of the computer.
It is a handy feature.

In your BIOS screen, they've made that feature adjustable.
On my older motherboard, the function was always turned on
and was set to "3". If the motherboard crashes three times
in a row, it resets the clock speeds to normal values. And
then you can go back into the BIOS, and re-adjust the
clock settings again.

So does this only work for the "reset switch"...

Because I also did "control-alt-delete" a few times because the "press F2 or
del to enter bios" message either didn't work for F2 or it went to fast to
press del
