EMM386.SYS Page Frame Uses "p3" Parameter, Not "p4"Last reviewed: November 23, 1994Article ID: Q63677 |
The information in this article applies to:
SUMMARYPage 598 of the "Microsoft Windows User's Guide" discusses two methods of indicating the beginning address of the expanded-memory page frame created by EMM386.SYS. The second method is incorrect.
MORE INFORMATIONThe first method uses the frame= parameter and creates a LIM 3.2-compatible page frame beginning at D000:0000. The second method is incorrect and is shown as follows:
device=emm386.sys 512 p0=D000 p1=D400 p2=D800 p4=DC00This command line in CONFIG.SYS generates the following error:
WARNING - EMM386 installed without a LIM 3.2 compatible Page FrameThe "p4" parameter on the command line is the source of the error. The fourth page of the page frame is specified with the parameter "p3", not "p4". Hence, to generate a LIM 3.2-compatible page frame, the command line should read as follows:
device=emm386.sys 512 p0=D000 p1=D400 p2=D800 p3=DC00A LIM 3.2-compatible page frame is required in order to use expanded memory with most applications that use expanded memory. If, while using EMM386.SYS, your application reports no expanded memory, verify the proper addressing of the pages "p0", "p1", "p2", and "p3", and/or use the frame= parameter to explicitly set the starting address of the entire page frame.
