UNKNOWN BIOS
4 long beeps, 1 short beep	this turned out to be a RAM incompatibility issue
Other events: on-board LEDs light up, fan starts up; all go off after beep sequence; sequence repeats after a few seconds
There was something wrong with the particular brand of RAM; the specs were all correct. Replacing with a supported brand solved the problem.
3 beeps, pause, 8 beeps	CPU compatibility issue
