32 bit EFI

I believe that has a 32 bit EFI.  If so then you would need an installer with 32 bit bootloader 
like the Debian multi-arch.

It seems that won't be able to attend the in-person meetup myself after all  :-/
Apparently, the local Berkeley Bowl store[01] I usually shop at has had some sort of electrical transformer issue requiring it to be closed until maybe 1-2pm this afternoon?
Besides participating virtually until the Berkeley Bowl reopens, might also spend the interim time-period attempting to dual-boot install Linux on the older iMac G5 desktop machine found several weeks ago.
It's apparently an iMac A1207 "Core 2 Duo" 2.16GHz 20"
Identifiers: Late 2006 - MA589LL - iMac5,1 - A1207 - EMC 2118

Quoting from this iMac specs'description at [02]:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The iMac "Core 2 Duo" 2.16 20-Inch features a 2.16 GHz Intel "Core 2 Duo" processor (T7400), with two independent processor "cores" on a single silicon chip, a 4 MB shared level 2 cache, a 667 MHz system bus, 1 GB of RAM (667 MHz DDR2 SDRAM, PC2-5300), a 250 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading DVD+R DL "SuperDrive", ATI Radeon X1600 graphics acceleration on a PCI-Express bus with 128 MB of GDDR3 memory, a built-in iSight video camera, and built-in stereo speakers underneath the 20" TFT Active Matrix LCD (1680x1050 native) display designed to "bounce sound off the desk below".

Connectivity includes three USB 2.0 ports, two Firewire "400" ports, built-in AirPort Extreme, and Gigabit Ethernet, as well as mini-DVI, which supports an external display in "extended desktop" mode (rather than just "mirrored mode").
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This iMac's RAM was upgraded to 3 GB.
Mac OS X 10.6.8 "Snow Leopard"[03] is installed and functioning fine on the current iMac's spinning-platters SATA drive.
Pertinent pieces of information on this iMac's T7400 2.16 GHz Intel "Core 2 Duo" processor are here ---> [04],[05],[06]

Am wondering which amd64 netinstall ISO to use for a dual-boot Debian Linux installation out of [07] (i.e., using debian-11.4.0-amd64-netinst.iso as opposed to debian-mac-11.4.0-amd64-netinst.iso ) ?
Recently downloaded both appropriate amd64 netinstall ISO's listed and am ready to make USB dd-images of both.

As far as HowTo perform the install itself, most of what have gleaned so far are from these few sites:
- HelloTech's 'How to Install Linux on a Mac'[08]
- The Debian Wiki's 'iMacIntel' wepage[09]
- The Debian Wiki's 'iMacG5' webpage[10] with its caveat "NB: This page is outdated and no longer applies to current versions of Debian. It is here only for reference purposes."
- The Debian Wiki's 'AtiHowTo' webpage[11]

Speak with some of you soon enough on Jit.si Meet :-)
