Tweaking eCS for low memory system
Andreas Schnellbacher:
Some more ideas:
* Remove DOS stuff from CONFIG.SYS.
* Remove multimedia, esp. the WPS classes.
* Remove printing from CONFIG.SYS.
* Remove TTF support from CONFIG.SYS.
* Lower the number of installed fonts and use only bitmap fonts.
* Disable folder backgrounds.
* Clean inis, also remove icons with Rich's tool.Of course uninstalling XWP would probably have the greatest effect. ;-)

I seem to recall that in one of my collections of books I have a "inside os/2 2.1" and a "Warp 3 certification" book, both of which I think had tips for optimizing for low memory systems.
I'll have a look and see if I can find those books, I'm sure the tips all apply to Warp 4 / eCS.

Thanks for all the info. Have to do more tests especially the fonts and MM stuff aschn suggested. To give you a clue what the hardware looks like, here is a picture. It measures 67x50mm and uses about 3W only. TFT, VGA, PCI, PS2, COM, LPT, USB, Intel LAN, IDE, Audio.... interface is onboard.
It's not necessary to use Warp 3 for this. This hardware has 64MB and it runs quite good with eCS and even with the server started. In the meantime I found a version with even 128MB. XWP shows about 70MB free after boot. Boot time from the CF-card is about 1:30 to 2 minutes which is acceptable as I plan to let it run all the time.
Currently I test this board on top of an evaluation kit which routes all signals to standard connectors. Next thing I've to do is making cables to attach a 1024x768 LCD instead the analog monitor. I've not decided yet if I should use the evaluation board for my final application or build my own interface for the parts I need. Target is to have a very low power OS/2 machine which seems to be possible with this board.

Andi, that looks very interesting. Could you say what it is and who the manufacturer is and where can I get specifications and manuals for it?
Andreas Schnellbacher:
Ivan, I thought the same and found that:
