Are you using the Amiga and Exec as an m68k base standard?

Kinda like how Mac became the PowerPC de facto standard for PowerPC? With OpenFirmware.

That's one way about it. I thought that may make it hard though. You have to take every Exec function and then DOS as it happens I expect and write an Amiga Exec wrapper to Atari, or Mac, or any other 68K platform.

Or am I misunderstanding here?

I thought arg[0] was usually the binary filename?

No, I can't do that, because absolute address 4 may not be available for me to use on an Atari etc etc.

When run on Atari, or Linux, I am "rewriting core kernel" - there is no alternative - the Amiga doesn't exist at all.

Anyway, here is the current state:

The standard - or indeed - definition - of PDOS-generic is that it takes a pointer on the stack to a list of functions such as printf. And that has been working for something like 6-12 months (can't remember - but could look it up) and those executables are available from pdos.org but until now I had no ability to personally test them.

If there was a reason to there could be an alternate interface, but that's what I use on all environments (e.g. 80386).

The format has not changed, it's just that the "old" sfs does not support new machines like tabor and X5000 so for you it will be safe.

But it's sure a little bit complicated for X5000 customers atm as they need to know how to prepare their own emergency boot pendrive if they want to run a better filesystem than what was offered when the latest os4.1 iso was shipped in case they run into problems.

A-eon has created a great emergency boot iso for the tabor, they should do it for the X5000 too.

PS. Also, did i understand it correctly, that they (os4 devs) tried to get rid of Varargs functions mostly from API ? Why i ask about, is that they say there https://wiki.amigaos.net/wiki/Linker_Libraries , that:

Intuition
CallHook() and CallHookA()
These functions invoke hooks. CallHook() expects a parameter packet ("message") on the stack, while CallHookA() takes a pointer to the message.
Replaced by IUtility->CallHookPkt() in V50.

Like, both were deprecated in favor of single CallHookPkt() , so to not have varargs function. Even if they have CallHook() still in utility.library (probably side effect of easy porting from os3 back in times), it all looks like that they want to get rid of Varargs one. Maybe because Varargs ones is potetialy not safe-ones, as can corrupt the stack in some conditions , etc, and that is the reassons they want non-varargs one to be used always ?

The reason for CallHookA() in amiga.lib can only be AmigaOS 1.x compatibility, as written in the NOTES of the autodoc.

Can AmigaOs4.1 access 4/8 GB of memory at all or is the maximum usage 2GB?

I mean, it didn't looks like for support OS1.x

Maybe issues was all this C compilers (and maybe assembler ones?) asking for things to be on stack, so to make live of assembler programmers easy or something ?

I tested two kind of 1333 MHz and one 1066 MHz. All worked ok.

I *didnt tested* 1600 MHz because the ones I have are *DDR3L* declared as 1.35V. DDR3 is usually 1.5V. Both are pin compatible but I simply didnt want to test that to avoid possible problems or to damaged board. Cant find any info that A1222 is compatible with DDR3L - maybe someone else can confirm?

Also other test results and compatibility reports from other A1222s out there are also usefull. DDR3 SoDIMM can be found in old PC laptops.

I'll investigate the remaining things "tomorrow". Source is in sourceforge and those two executables are available as an attachment on the other forum I mentioned previously.
