Is there a memory location or system call that I can use to find out the address of the start of the memory mapped video RAM? I'd like to do some things by directly 'poking' them to RAM, which is easy enough to do, but if I hard code the start address, it won't work on machines of different sizes. (I'm just an old Apple ][ hacker at heart). -- Dennis Dale AT&T Bell Laboratories - Naperville, IL ihnp4!ihlpf!dennis

The global variable ScrnBase holds the address of the start of the main screen buffer. See IM II page 19 for details. -------------------------------------------------------------------------------- Dean Yu | mystone@caen.engin.umich.edu | This space intentionally left blank I'm too young to have an opinion | --------------------------------------------------------------------------------
