My Dell does the same thing. Is this a universal sort of thing that Apple has adopted ?
Back in the day, PC's could run a memory check *after* DOS booted, if you added that software.
It was Apple that first did the quick diagnostic test in their ROMs, back in '84. The BONG means the memory, bus, and processor checks passed. Depending on the hardware failure, instead of that satisfying bong, you get multiple beeps, a chord, or the sound of breaking glass; each meaning something specific failed. Then, if the monitor driver in the ROM'd OS could initialize, the little sad Mac with the hurt eye and the error code would appear...
