Well I decided to simply enable #define DEBUG in the stram.c. Below you'll see the result for video=atafb:vga16: atari_stram_alloc(size=0004c000,owner=atafb) atari_stram_alloc: rounded size = 0004c000 atari_stram_alloc: after mem_init, swapping off, get_pages=00f80000 and then in atafb: atafb_init: screen_base allocated at 00f80000, size=0004c000 set_screen_base(virt=00f80000, phys=01b80000) and that's it. So atafb is perfectly OK, it just believes the stram_alloc routine to return valid RAM. Petr
