Another silly question - is it easily possible to do graphics, i.e. pixels and lines etc, in a Window size DOS 'box' from within Windows? It seems to be limited to text only.

yes, just like you would in DOS. Only problem is with VESA linear frambuffer, it reports it is supported but fails when you try ti use it, that's why most DOS games crash under windows.

The rules I follow are:

1. Never use VESA
2. 13h seems to work well
4. Ditch EMS(mostly your board's fault not windows) and use XMS.

Perhaps the problem is in accessing the physical address to VESA framebuffer? What if you allocate the LDT descriptor (with DPMI) and map it to that address? I have to try, when I have some time...
