1. All UEFI bios computers must have a FAT32 partition to boot from.

Yes.
That has become the standard for UEFI bios.

2. If it is the user, what are the reason(s) that would make him/her choose to have a second partition?
2.a I have seen post claiming that they need the 2nd partition to enable file transfers between Windows an Linux. Unless it is Win-7+, I have always been able to transfer between the 2 operating systems.
2.b For storage of a particular file type
2.c For launching a particular system
2.c To launch each puppy from a different partition
2.d To accommodate these partitions, the user invariably chooses grb4DOS as the boot-loader

Sure, all could be the reason to have other partitions.

Do you have to have more than one partition with Puppy?
No.
Puppy works fine on any format.
Other formats have better features than fat32, so why not make other partitions, using those formats, and use them for the main Puppy install.
One big reason to put Puppy on a Linux format is to get option to make save folder.

Quote:
I see in tahr-6.0.6 that 666philb provides both isolinux.cfg and grub.cfg.

There is those two and also some other new files, now in Puppies, that have UEFI in the version name.
Those are added files that are needed to boot on UEFI computers.
The UEFI Puppies actually have what is needed to boot on UEFI bios and what is needed to boot on the old bios.

Quote:
What are the reason(s) that would make a developer choose to have a second partition?

Puppy version developers do not decide on partitions.
They just develop the Puppy iso package.
Partitioning is the users choice.

Quote:
YaPI deliberately create second partitions.

Yapi does not create any partitions.
It works with what it finds already there.
The install location is the choice of the user of Yapi.
Now, when it gets to installing Grub4dos bootloader.
The auto setting is install to the first partition, if there is more than one partition on the drive.

As far as I know you do not need more than 1 partition.

bigpup agrees. I suggested that the 2nd partition is a user option which you indirectly agree, (reason: facilitate Puppy<=>Windows file transfer). But whereas you set the boot flag on the 2fs, I got the impression from bigpup, perhaps wrongfully, that a bootable FAT32 was needed. It would seem from your experience that a FAT32 is necessary but not necessarity bootable for UEFI. Or is it the first partition that must be bootable?

@bigpup
I had expected a comment on my Summary and Conclusion by now. Surprised

In light of peterw's experience with 2 partitions (FAT32 and 2fs), but booting from the 2fs, would you like to comment, please?

Then to add to the confusion, version2013 wrote:

UEFI bios has a normal mode of operation and a non-normal mode of operation.
You can select it to use a non-normal way to operate.
This affects how it works.

It depends on the manufacturer of the computer and how they decided the UEFI bios will work.
They have some options for how they want the UEFI bios to work on their hardware.
They could require a fat32 formatted boot partition as the only one they will allow to boot from, even with secure boot disabled and or legacy mode enabled.
But they all have to support booting from a fat 32 format.
It seems the standard for normal UEFI booting is from a fat32 formatted boot partition.

Quote:
legacy mode is a state in which a computer system, component, or software application behaves in a way different from its standard operation in order to support older software, data, or expected behavior.


As I stated in a earlier post:

If you disable secure boot and/or enable legacy boot in the UEFI bios, it may or may not apply needing fat32.

Basically, if you do this, the UEFI bios is not working as a normal UEFI bios. It is working in legacy mode and mostly like the old bios way.
So, old ways of doing things may work OK.

version2013 wrote:

My 64bit laptop has:
secure boot disabled
legacy bios enabled

So, he is not in normal UEFI bios mode of operation.
That is why his setup works.

The idea behind the Puppy versions, that have UEFI in their name, is to have everything needed to be able to boot on a UEFI bios computer, without having to turn off secure boot and or select legacy boot in the UEFI bios.
That also requires a fat32 boot partition and the boot files on it as the first partition seen by the UEFI bios.
Oh, and it may also have to be using a GUID Partition Table (GPT).

I have never really tried to do it with UEFI bios setup normally, because I boot from USB drives or CD/DVD.
Secure boot has to be turned off, on my computer, to even get an option to boot from a USB drive or CD/DVD.

What do I do.
I go into the UEFI bios and turn off secure boot and or enable legacy boot.
I boot Puppy the way I have always done it.
Any way I want to.

Thanks
You threw a "spanner in the works" with the addition of secure boot. Trying to understand this is giving me a headache ... I'll drop it , at least for a while. What I can and will use is the procedure you personally use.

I'll have to visit my BIOS settings, which I haven't done for soooo long - no need.
