It's interesting that different tones were used. That would be difficult to document in any medium that doesn't support embedded sound files.
Many BIOSes used a sequence of beeps to convey the error code. Here's a page about this (found via googling for 2 seconds, so standard caveats apply): https://www.computerhope.com/beep.htm https://www.computerhope.com/beep.htm
- Stratoscope 6y agoAh yes, a slow Morse code dah-dit-dit-dit is burned into my mind from when my original IBM PC had memory errors! For the new Lenovo beeps, the idea wasn't that you would listen to them and look it up in a doc like you would with the old PC beeps. They were intended for people who would call customer support and say "my computer won't boot and it makes these strange sounds!" The CS rep would run the app while on the phone call, have the customer reboot, then the app would listen to the call, hear the beeps and display the error code and recommendations. https://www.youtube.com/watch?v=X2rzkO3jwko https://www.youtube.com/watch?v=X2rzkO3jwko
