G5 5590 Firmware Update 0.1.12

Hi,

I recently did a BIOS update on my system (1.12), which caused over-heating, and on Dell's advice, I rolled the BIOS back to 1.11, which was the last stable one.

Last night I got the notification from Windows Updater, however, that there's a Dell, Inc - Firmware update (0.1.12.0), and I just wanted to double check that this doesn't include a BIOS update as well, as I really don't want to risk my laptop at this point. Any help would be appreciated.

Thanks!
