Firmware update failed for MacPro 2006 1.1

Upgraded my system with 2 Xeon X5365 processors and they just work fine. After that I used the firmware upgrade tool for going from 1,1 to 1,2. That did not work. Any suggesstions why that's the case?

Does it influence the performance in any way when the firmware is not updated?

Is this a good question?

I also failed at using the Mac Pro 2006-2007 Firmware Tool. I click on Upgrade firware, it creates a ram disc, copies stuff and finally tells me to shut down the machine, start up holding the power button until the power led flashes or I hear a sound... then the Apple logo apperas along with a progress bar, for just a glimpse, then disappears and the machine boots into the primary OS... no upgrade, no progress bar progressing.

The firmware after that is still the 1,1 firmware and not 2,1 as it should be.

Your machine won't take it.

Pre-Installed MacOS: X 10.4.9 (8P4037) Maximum MacOS: X 10.7.5*

Mac Pro (8-core) MacPro2,1 MP21.007F.B06 (EFI 1.2) 1.15f3 (SMC 1.1)

Most firmware updates are automatically installed when you update or upgrade OS X. Some firmware updates are also available as downloads you can install manually. If your Mac needs a firmware update and it isn't installed automatically, check to see if a manual updater is listed below.

If you don't see a firmware version listed in this article, it means that either a firmware update is only available as an automatic update, or no firmware update is needed.

Please see http://lowendmac.com/2014/modernizing-th.... There is indeed a lot that can be done to the MacPro1,1 to have it run later versions of OS X. This is typed on a MacPro1,1 which happily runs 10.9.5 and 10.10; and as a result they are not limited to running only up to 10.7.5. I was delighted to discover that, and it's been a fun learning curve getting it to work. :-)
