Why won Freesco boot without a monitor / keyboard?
This is normally not a Freesco problem at all but a BIOS problem. Many BIOS’s, by default, report an error if they do not have a keyboard connected (usually the idiosyncratic “Keyboard not found. Press F1 to continue”). If this is the case, you need to enter your BIOS and (very carefully) change the options to allow booting without a keyboard. This should not be attempted by amateurs. The option is usually enabled by setting “Keyboard” to “None” or by setting “Halt on All Errors” to “Halt on All But Keyboard” or “Halt on None”.
