iMac update - strange boot bleep?

[kjid]

I just upgraded with the thunderbolt upgrade, when it restarted it made a deep ±3 sec long bleep and then it rebooted again to the grey apple screen but with a loadbar under it.

When it was done loading it booted normally and the update has been done.


Is that the normal way upgrades happen? Or did something go wrong?

iMac (Mid 2007) and later models: About startup tones

1 long tone when holding down the power button = Firmware upgrade in process.

Thanks. I didn't hold the power button, but i guess its the same as rebooting

Welcome to your first firmware upgrade.
In future make absolutely sure that you don't panic and turn off the computer mid-upgrade as a friend of mine did who had just bought a powerbook Mac.
Pretty much killed it until Apple gave it the kiss of life.

Haha, yeah that would be freaky the first time. Windows Update doesn't check for manufacturer firmware upgrades at all; just driver, stability, and security updates. You can download bios, optical/hard drive, etc... updates from the maker's website usually. I had a Dell that did a similar beep when the bios was upgraded.
