Is it possible? OS/2 for Power PC in Action on Cebit 95?
Sigurd Fastenrath:
I am wondering wether or not this kernel of PPC Edition does have the 4GB RAM Limit as well, and in addition the "Free RAM" problems.

Well, being 32 bit, it would have had the 4GB ram limit as well. What it wouldn't have had was the low vs high memory thing that we have. That's due to the i286 legacy and up to Warp v4, our address space was limited to 1GB, with half given to the kernel, then more for DLLs.
I'd assume that it didn't have the free bug that our kernels have had, it is really a bug.
What would have been really nice is if IBM released the source. Sounds like they had the copyright and it was fairly portable.

For completeness, there is the OS/2 museum take on it, http://www.os2museum.com/wp/os2-history/os2-warp-powerpc-edition/.
Someone recently asked Michal for an image of it, he said sure, if he can find it and the hard drive still works.

Ahoy Dave !
Thanks for greetings :D
And for answering ...
Yepp, this way I wrote : "among similar ones"
Also you are absolutely right right, OS/2 Museum link covers a more detailed and accuraate answer for the initial question of Sigurd Fastenrath,
however I intended to answer to Martin Iturbide with my links, and on macintoshgarden site there are downloadable materials' links there ... and might he can use them somehow against my last pessimistic paragraphs ;)

The person was Sebastian Blanco ... well not the football player from Argentina :D ( hehe
, I found him first ) but a developer from Spain (https://sebasblanco.com/)
Interestingly not he was from some OS/2 related project, but the requested one to provide DD image -- and mentioned by you -- Michal Necasek from osFree project.
Quite surprising, indeed ?

Hello everyone,

I had a look through OS/2 PPC to see what it was made of.
The DOS is based on PC-DOS 6,30, and has REXX installed as well. There is a help command, which functions as the PC-DOS 7 help, but loads the OS/2 CMDREF instead. Although the rexx is similar to the PC-DOS 7 rexx, command.com will not run rexx.bat scripts like in 7.0 and 7.1. Unlike the intel version of OS/2, the DOS is pretty complete. It's in the various reviews I write on DOS as PC-DOS 6.32. (see http://www.os2fan2.com/files/pcdos.pdf )
The wallpapers are similar to the 3.0 set, but there are some 4.0 features in there, which is why I group it under 3.5 (3.1 is a version number i had reported by tcmdos2 under Warp Connect 3.)
OS2 PPC does indeed look like 3.0, iconwise, but since all the books on OS/2 Warp is 3.0 stuff, i see that even OS/2 4 server reverted to the 3.0 icons.
