First Time Boot up the 2008 MacPro3,1

Here are the updates:-

I got the dosdude1 program to patch the Apple installer.

I downloaded the Mojave installer from Apple and even verified good by the patcher program.  But when it actually ran it complained can't mount.  I reformatted the USB thumb drive one more time, downloaded the patcher program one more time but still no go.  I don't find lots of information other than you must have the wrong install program (from Apple?) or you need another 16GB USB thumb drive.  Oh no!  OK, so I tried using the patcher's program utility to download the mojave again, instead from Apple, I don't know where it was from but worth a try.  This was like the last resort as it would take some 30 minutes to download.  Hey this time it worked.  So it's a mystery to me.  As the original mojave is from Apple and checked ok even by the patcher program why it failed I don't know.

So the patcher program created this modified installer which doesn't discriminate against old hardware or something something so my MacPro3,1 from early 2008 can install mojave.

I checked the installers by eyeballing them they look the same to me.

My build isn't quite ready as I am still waiting for the power cable splitter to power the STA SSD which is going to be installed on the optical drive bay.  It doesn't come with any drive at all.  So I have no way of booting it up from any existing old OS.

Anyway, I tried to boot from the USB drive.  And the MP came alive!  Since the SSD is not ready so I can't really install mojave from scratch.  The odd thing is I have another 3.5" HDD in the 2nd bay, I wonder why it can't see it.  I hope I can install and boot from the lower bay of the 5.25" optical drive bay, that's the goal.

I guess I need to wait till Tuesday to find out.
