The DOS problem involves Partition Magic.  When booted from a DOS 
floppy, PM 3.05 cannot work properly and PM 6 won't even run.

On the machine in question I used a cloned HDD and only 256M RAM. 
OS/2 (W4) will boot, even Uniaud sound works on board, but I have no 
access to the desk top; no cursor activity and tab and arrow keys do 
nothing.  And of coarse, ECS says "OS/2 not supported"
