[Qemu-devel] O/2 Warp 4 and eComStation

[ecs user]

There are problems booting Warp4 and eComtation. 
System hangs while loading certain drivers (IDE, DASD,
Diskette). By repeatedly booting, sometimes can get a
successful boot. Might be some type of timing issue.
 
I have some small test images that demonstrate the
problem. Are there any developers here familiar with
OS/2 that could look at this issue?

Is there a place I can upload the images (15MB)?

Try to boot it with less than 64Mb (48Mb for example).

OS/2 hangs when 64Mb are informed in the standard way they seems to  
check that in some strange way.

No matter it is 4.0, 4.5, eCS or whatever.

    Could this be because of OS/2 memory handling differs from many 
others in this way:

             Memory "filling" is started from "top" to "bottom" 
?(highest address first)

Surely.

There is also a problem in OS/2 16-bit with the 15-16Mb portion,  
seems that the OS/2 pretends to put there something (the BIOS,  
surely, as this version was able of loading a disk-based protected  
mode BIOS' based ROM and had one for AT and one for PS/2 machines,  
the ABIOS was called, see old OS/2 books) in RAM and maybe is making  
that portion of RAM to appear at that location, and if that portion  
isn't empty (has real memory) the system hangs.
