    11The CONTENT of pDevCaps ends up in ES:BX and points to the stack because the trap screen shows that ES == SS ! In other words: pvpfsi->vpi_pDCS is a stack address and THAT is definitely wrong ! [[BR]]
    2 And reading the pDCS via an OS2DASD.DMD dedicated strat1 command "GetDeviceCaps" is NOT wrong and I was NOT using the strat2 entry point to do it. I was using the strat1 entry point of OS2DASD.DMD to do it ! Please have a look at routine "ReturnDriverCaps" that you commented out.
