For those interested here is the post from Lars and I'm sorry it is an 8 core processor.

Thanks to all who responded.
I now got it to work correctly. For the record, I have a AsRock Extreme4
MOBO which means it has an 8-core AMD CPU and an AMD SATA controller.
1) in order to properly boot the eCS 2.2 DVD I HAD to set SATA mode to
"IDE compatiblity" and ONLY enable DANIS506.ADD in the preinstallation
selection menu.
In short I had to disable OS2AHCI.ADD in the preinstallation selection
menu. That allowed me to finally see my harddrives during the
installation phase and therefore to install to them.
Trying to boot the eCS 2.2 DVD with "AHCI" enabled is plain impossible.
2) After installation I could leave "IDE compatiblity" mode enabled
during normal operation and use DANIS506.ADD and DANIATAP.FLT. However I
decided to use AHCI for the improved performance.
3) I therefore remmed DANIS506.ADD and DANIATAP.FLT in config.sys and
added OS2AHCI.ADD instead. However I HAD TO specify the /!r switch to
prevent the driver from resetting the SATA ports.
Now everything is fine. Note: even my 8 CPU cores work just fine.
I'll now try and enable NCQ.

I guess this is following my Experiment called "Maximum Warp PC" I made earlier this year (the same hardware),

In the meantime I have found out this:
1) I had "AHCI BIOS" enabled in UEFI BIOS. What it does is to enable some AHCI BIOS that shows which hard disks/CD-ROMs are connected to the AHCI ports and if SMART is enabled for them, and obviously some other stuff. Once I disabled that I was able to boot the eCS 2.2 beta DVD even in AHCI mode.
Note: disabling "AHCI BIOS" did NOT mean to disable AHCI ! There was another UEFI BIOS configuration option to select among IDE compatibility/RAID/AHCI. THIS is the option that selects if you use AHCI (or IDE compatibility mode instead).
2) eCS 2.2 beta uses the 14.106 kernel. It looks like this kernel fixes a couple of things compared to the 14.105 kernel that came with eCS 2.1. I'd say it's the best kernel (and also the last kernel ever distributed). I am using all 8 cores and that works fine too.
3) On this MOBO, ACPI is a necessity. If I don't use ACPI.PSD on this MOBO, the kernel will trap right away already on system start.
The eCS 2.1 install CD does not enforce the use of ACPI.PSD and even if it did, the version of ACPI.PSD that was delivered with eCS 2.1 was still heavily broken. eCS 2.2 on the other hand selects ACPI.PSD as a default and it's also the 3.22.03 version which is the latest at present date. It works considerably better than early versions of ACPI.PSD.
4) if you have AHCI enabled you can and should set up the installation process to ONLY use the OS2AHCI.ADD driver. That is you neither need DANIS506.ADD nor DANIATAPI.FLT nor the IBM pendants and you can deselect these drivers already in the custom installation menu. However you might need to specify the /!r parameter on the OS2AHCI.ADD command line. This will prevent the AHCI ports from being reset. Resetting the AHCI ports results in a boot hang on my system.
In the meantime I have enabled "native command queueing" (NCQ) by specifying the /f /n parameters for OS2AHCI.ADD. Works like a charm. I am using OS2AHCI.ADD version 1.32 which is the latest one at current date. I seem to remember that eCS 2.2 beta DVD also has this version.

Hi Lars,
congratulations for your progress!
May I ask: wich grapic card do you use?
With Panorma?
Holger made some efforts to solve the SMP Problem with SNAP.
Lars:
pci.exe reports this for the graphics card:
Vendor 10DEh NVIDIA Corporation
Device 0FC6h GK107 [GeForce GTX 650]
I am using Panorama 1.06 (the latest version, currently).
I have not tried with SNAP but I expect problems on an SMP system. At least that's what is said about SNAP and SMP systems. I don't know if SNAP supports this NVidia chip. Is there a readme for SNAP that could tell me ?
Is there some BETA version of SNAP that has fixed SMP support that I could test ? I'd test even if SNAP only offers VESA support on this chipset.
