** I have an AT frame grabber whose video RAM is mapped into addresses above 1 Mega byte. (Extended Memory ?). I understand that the only way this memory can be accessed under current PC-DOS / MS-DOS is via a driver like VDISK.SYS (on IBM PC-DOS diskette). Is there any PD driver source code which provides copying services between AT memory above 1 Megabyte and regular DOS memory? I need straight memory copy ( 1 segment is fine) without any formatting of any kind. Any lead to such a beast is appreciated. Thanks in advance.
