Title: eCS 2.0 RC1 / OS/2 and 2GB of RAM
Post by: djcaetano on 2007.08.16, 22:12:06

  Hi,

  Some time ago I said I was not being able to load more than 500MB (or so) on my SMP machine (now running eCS2.0 RC1), even if the system said me there were a total of 2GB of memory (1700MB usually free). When tried to load anything above 500~600MB the system refused to load and report "not enough memory" (this goes both on SMP and on UNI modes, but on SMP is more frequent).
  Today I decided to do some tests and removed one of the two 1GB Kingston DDR2 memories. Well, the system is now with only 1GB but now I am able to use it entirely (no more 500~600MB "memory limit"), both on UNI and SMP modes.

  I guess it is a problem with the space spent by OS/2 to manage memory, but I am not sure.
  Anybody had ever been able to use OS/2 on a system with 2GB of RAM (or more) and use this memory fully?

  My kindest regards!

Have you swapped the memory? You know stick works at 1GB RAM. Need to know if it is the memory (hardware) or softare.

My desktop system has 3gb of RAM and runs eCS v2 beta 4...... Asus M2N-E motherboard, Athlon64 X2 6000+ processor....

  Maybe there is really some incompatibility with my system (ASUS P5GZ-MX with Core 2 Duo E4300, 2x 1800MHz).
  Man, it sux. Besides the random lockups (more using SMP than using UNI mode), this weird memory limitation. :/

I have had weird problems with some ASUS MoBo's and Warp/eCS (WSeB/eCS 1.2R). The problems seem to vary depending on board model. One of them, the problem exists in Windows XP and eCS (recognizing SATA drives correctly on soft boot - which a BIOS update was supposed to fix, but didnt quite fully address).

We are currently looking for a really good board for eCS - especially since they are for servers... the best results we have had so far are buying used Netfinity's and e-Series machines (which works great for us - but is not the solution we would like to use for our customers). If we find anything, we will post the info.

  Ha! Today I could update ACPI to the newest version 3.xx and the 1GB memory limit problem is gone!
I had to update DANIS and DANIATAPI also, since the system hangs with the newer ACPI drivers and
old DANI drivers.

  Problems solved! :)
