@TheShortTimer and me were talking about the 32-bit EFI that no non-Apple laptops of the time had.Every other laptop of the same vintage had those same limitations.
EMC2139 has 64-bit, according to Everymac.
Well, no it doesn't. It says it can boot in 32-bit mode running SL. The EFI is 64-bit. Having said that, the machine might be *set* to boot in 32-bit mode, if I read the footnote correctly. Will have to check. Put a fresh install of Lion on it until such time as I gigure things out.This says otherwise.

* These models are believed to be hardware capable of booting MacOS X 10.6 "Snow Leopard" in 64-bit mode, but it appears that they have been blocked in EFI from doing so. Unauthorized hacks are available.
To determine if your particular Mac has a 32-bit or 64-bit processor, 32-bit or 64-bit EFI, and whether or not your Mac is set to boot/running in 32-bit or 64-bit mode, an easy way is to download Startup Mode Selector.

ioreg -l -p IODeviceTree | grep firmware-abi
in Terminal to see what type of EFI you have.No worries!Runioreg -l -p IODeviceTree | grep firmware-abi

In any case, EveryMac does say the EMC 2139 is EFI64 so if that’s accurate, I must have mixed it up with the EMC 2121. Sorry.
Nope. 32-bit Mac Pro 2,1 final software was Lion, so that must be 32-bit capable. My first Mac and my first Macos!Lion, a 64-bit only OS is supported.
Final Lion runs on 64-bit CPUs (which all Mac Pros have) only but does run on Macs with a 32-bit EFI.Nope. 32-bit Mac Pro 2,1 final software was Lion, so that must be 32-bit capable. My first Mac and my first Macos!

As @Amethyst1 has pointed out, there are no 32-bit Mac Pro's - otherwise my Mac Pro 1,1 wouldn't be able to run Mavericks and El Capitan - with a bit of fiddling.
The early machines are however saddled with a 32-bit EFI - which needlessly and annoyingly blocked their official access to later macOS releases and also requires workarounds with newer Linux distros.
TheI would already have patched it to High Sierra […]

’s “Merom” CPU doesn’t have SSE4 and can’t go past El Capitan no matter what. Worse yet, going past patched Mountain Lion loses graphics acceleration, making OS X basically useless (IMHO).The link is seemingly permanently broken...Easily missed in the text because of the font size. I've enlarged it!
A 32-bit Linux is definitely in its future, then!TheMacBook2,1

The Penryn CPU in the 2009 mini on the other hand can run Sonoma with a few patches.TheMacBook2,1

I cannot access it at all from here, no matter what I use. UK-based.
That does return EFI32, so will check out the Startup Mode Selector.Runioreg -l -p IODeviceTree | grep firmware-abi
in Terminal to see what type of E
That worked fine. But not a fan. Interestingly, the display on the right shows that the CPU is throttled as per the duff battery. OK. Will go back to Lion and keep it there. Battery is on its way, and Lion performs quickly anyhow, so should be a whizzer with new battery.Will now try a 32-bit Antix and see what happens.

I’d be inclined to believe what the system says. Is it an EMC 2139 for sure?Startup Mode Selector changes nothing useful in this context, but continues to insist on there being a 32-bit EFI, despite what Everymac says.
How does it fail?64-bit Antix live USB will not boot.
Maybe Mint has the right boot loader?64-bit Mint will boot and install, but not run once installed.
That's what it says on the chassis. And the OS returns 'late 2007', so one might assume there's been no logic board swap.it an EMC 2139 for sure?
Never had many problems with Linux on PCs, and not that many on Macs, to be fair. Except cMP 2,1 - never got Linux working on that!Unfortunately it's not uncommon for Linux distros to simply fail to work - even when you've chosen the right version, followed all of the instructions and ensured that your install media has been prepared correctly. I've experienced this with Macs and PCs and had episodes where I couldn't even get pass the installer menu!
(Cue howls of denunciation from Linux devotees.)
