What switches do you have on the DANIS driver? The /!BIOS one?
Try running DANIS with NO switches what so ever. Also, remove one of the two drives. See if you can narrow down the issue.
I tested the system only with SATA HD and had some success (more on that later). Then
I tested it only with IDE HD and... it seems the problem is really with OS2LVM.DMD, it refuses
to work with my IDE harddisk (!?!), the "OS/2 Cannot operate your harddisk" error shows
up using IBMS506 or DANIS506, whatever switches are used on the adapter/device
initialization. This is bizarre, some kind of ugly regression. The problem happens with and
without ACPI.
About the "success" using SATA HD, it was limited. First, SNAP gave a weird result:
as soon as the graphical shell is started, my monitor (22" LCD that supports up to
1400x1050) goes out of sync ("No Signal"). This is weird, since I use SNAP for years
on my OS/2 4.52 without any glitches. My video board is a Matrox MGA-550.
This problem happens with and without ACPI.
I tried Panorama and then the system booted (with the inherent performance
problems) but then I noticed something: the partition where I would like to install
eCS 2.0 silver is located at my IDE HD (my test partition). Since I cannot boot to
that harddisk, no donuts for me.
As a remark, no matter the harddisk configuration, the "Legacy" mode of
eCS
never complete the boot. It always locks on the first thing loaded:
PCIBUS.SNP.
I really think it is very cool and I really expect eCS to boot and work fine with
modern hardware, but I find it very odd this regression, since it is not working
in a machine built to run OS/2 (every piece of hardware was selected and
bought due to its compatibility with OS/2). Even if newer eCS features do not
work on this old piece of hardware, I would expect at least to be able to install
it and run it in the same way I did using OS/2 4.52.
(I remember having some problems with OS/2 4.52 on SATA+IDE configuration,
but there was no problem when installing OS/2 on the IDE HD after disconnecting
the SATA HD).
I am not a noob OS/2 user, I am using it for almost 17 years now... but this
problem is really puzzling me.
I thank you for the help and I hope someone come up with some new
ideas so I can try to solve this problem.
Regards!
