How can I tell if my Firmware was updated?

[LarryJoe33]

Not sure if anyone else experienced this or if it was normal, but installing beta7 yesterday, my system rebooted very quickly into the install and appeared to be flashing the firmware. The bar (of the flash install screen) never moved visibly to the right and the system rebooted three times (to the flash screen). The first came with a long beep, two more reboots, and then a boot into beta6 without installing the update.

Went back to the App store, this time I still got the firmware install reboots and beep, but it did install the update.

Questions: What does the long beep mean? How can I tell if my firmware is updated? I don't see any dates?

Yes, thanks, I have read this. It doesn't say how to tell the date of the firmware I am running. The firmware listed here is also very old and surely not what was in yesterday's beta. I am trying to find the date of the firmware I posted in the screenshot above.
