Description of problem:
A successfully installed FC6 on a Mac Mini Core Duo will not boot if a monitor
is not connected.
Version-Release number of selected component (if applicable):
Suspect problem with anaconda
Install FC6 on Mac Mini (intel) with Bootcamp. Configure network, test ssh.
unplug monitor, reboot using ssh. system does not come up.
No network connections possible.
this is important for using mac hardware with Fedora Core for servers.
If you then connect the monitor, where is it sitting?
I didn't see anything after reconnecting a monitor but just found this info:
Running without a screen
It is important to test that your Mac Mini will boot correctly without a screen.
In particular, if you rely on the Apple "Boot Camp" firmware update (which
provides a legacy BIOS, so that the machine can be booted like a conventional
PC), then you may encounter trouble with this, because the VGA BIOS which the
machine installs typically blocks trying to communicate with the monitor using DDC.
If you need to use the "Boot Camp" firmware, you will need to prepare a simple
terminator to convince the machine that a (non-DDC) monitor is attached. All
that's needed is to connect a 75Ω resistor between pins 2 and 7 of the
(analogue) VGA connector. The easiest way to do this is to buy a male DB15
connector (a "VGA plug") and appropriate resistor, and solder it between pins 2
and 7 on the connector. Fit a hood over the connector to prevent damage in handling.
I guess some info on how to create a custom boot without "Boot Camp" would be
This is a hardware issue -- we really don't have a good way of supporting EFI
only booting (and doing so ends up leaving some of the hardware in less than
