void initg(void)
{
FILE *f;
char *a;
short cfg;
__dpmi_meminfo mi;
union REGS inr,outr;
f=fopen("config.ini","r");
fscanf(f,"%d",&cfg);
fclose(f);
inr.w.ax=0x4f02;
inr.w.bx=0x101|0x4000;
int386(0x10,&inr,&outr);
mi.size=(unsigned long)307200*4;
mi.address=(unsigned long)cfg<<20;
__dpmi_physical_address_mapping(&mi);
__djgpp_nearptr_enable();
start=mi.address+__djgpp_conventional_base;
}

this should work;  in config.ini should be the adress (in megabytes) of the
linear frame buffer, that's something i was too lazy to code :)
