If you feel like being ATI-specific, you can program it's linear mode yourself and access the memory at (0xe00000000 + physical linear address). However, the page-handling code in go32 is efficient enough that the gain for using linear mapping is only a few percent. It's better to use the page mapped mode and libgrx drivers, since you are still portable to any graphics card. DJ
