BIOS shadowing is used to increase performance of BIOS calls by mapping the slower (E)EPROM based BIOS code into a section of faster DRAM area. The VRAM (Video RAM) will still be on the video card. It is mapped into the standard VGA address space 0xA0000 to 0xC0000 always (with/without shadowing to BIOS) Sometimes, even the video BIOS may be shadowed. But all this only works if the OS calls the BIOS. Linux does not use the BIOS for anything other than during the bootloading phase. In fact, this very reason of not using the BIOS has led to projects like FreeBIOS that try to put the linux kernel into the (E)EPROM used by the BIOS. This way, linux has been booted in less than 3 seconds. However, not all motherboards/chipsets are supported and also, no more Windows (because there is no BIOS!) -Naren _______________________________________________ linux-india-help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/linux-india-help
