  • Re: 256Mb Extender Problems

    My problems with GO32 and QDPMI went away. Perhaps as a
    result of changes to DESQview/X's Virtual Memory Manager.

    As a result I only need to exclude one 4Kb block from
    QEMM386's management for CLOAKING, the only DOS extender to
    complain of too much memory:

    NoUseRAM=262132K-256M ;4K for CLOAKING v2.01

    I recently increased memory to 256Mb, only to encounter DOS
    extender problems (details below). CLOAKING reported
    "Memory configuration too large", QDPMI "Paging Violation"
    and GO32 hung without complaint.

    On the verge of asking your help, I discovered a fix by
    excluding up to three 4Kb blocks from QEMM386's management:

    NoUseRAM=262124K-256M ; 4K for CLOAKING v2.01
    ; 8K for GO32 v1.12.special1
    ;12K for QDPMI v1.10

    While I'm not desperate to reclaim the 12Kb of my 256Mb,
    someone here might know what's going on or find this
    information useful.
