I am writing a program that uses VESA mode 10F, 320x200x16.8M.

I have got the physical memory adress from the modeinfo block.
It is 0xe1000000 ...


I want the modeinfo.physbaseptr into an
    unsigned char *bigbuffer;

... to be able to do things like

bigbuffer[x*3+y*3*320]=red;
bigbuffer[1+x*3+y*3*320]=green;
bigbuffer[2+x*3+y*3*320]=blue;


I know it has got something to do with __dpmi_physical_address_mapping()...

But I'd appreciate some help(or maybe an example?)

Thanks!
