You're correct: it was a typo.
"Keepy" member of this forum has referred to AWARD bios.....beep codes.
Someone else was referring to IBM bios beep codes.
P5W HD Deluxe HAS an AMI Bios. This is not an assumption.
And AMI has its own specific beep codes, which isn't an assumption as well.
However, I've noticed diverse posts that the specific sequence of beep codes seemed to be related to Graphic Cards. That's why I started this thread, hoping that someone, particularly someone at ASUS, could reveal what's really going on.
This thread could become interesting........
Keep us posted!!
