Basically beeps ni standard on semua PCs. Tapi cam cloud_hardcore cakap, lain motherboard/BIOS lain sket beeps dia... and kat some newer Dell PCs, kena tengok combination lampu kat depan.
Anyway benda ni penting nak tau especially bila nak troubleshoot PC problems... benda ni dah banyak berjasa kat aku sebab senang nak pinpoint problems.
