I got super frusterated with this ... i heres my simple line that works for everyone else but not me ... unsigned char* vidmem; vidmem=(unsigned char*) (vbeinfo.physbaseptr+__djgpp_conventional_base); vbeinfo is a structure with all the vbe info .. previously retrived, i am sure of the correct data because i can do a get info command and retrive all the right values from it .. whenever i try doing vidmem[x+y*xlen] = color; it crashes on me error code 255 .. im not sure what im doing wrong anymore .. iv looked at other code that iv written eirlier, and i cant see any differences :( iv looked at other peoples code, and still no differences ... i am loading __djgpp_nearptr_enable(); and ending with __djgpp_nearptr_disable(); ... if you have any ideas i would love to hear em :) -V01D
