This article was previously published under Q77369

SUMMARY

The Microsoft MS-DOS 5.0 MIRROR deletion tracking utility may be loaded high automatically without specifying a LOADHIGH or LH statement.

MORE INFORMATION

To following are requirements to automatically load MIRROR high:
  • An 80386 machine (required to load any device drivers and/or TSRs high under MS-DOS 5.0 memory management).
  • Include the following lines in the CONFIG.SYS file:

    device=c:\dos\himem.sys
    device=c:\dos\emm386.exe NOEMS [or] RAM
    dos=umb

  • A majority of the upper memory area (UMA) must not already be occupied by other device drivers or TSRs.
  • There should be an upper memory block (UMB) of at least 20K available even though MIRROR only occupies 6.4K of UMA after loading. The additional memory is required for initialization code and to preserve room for a growing deletion tracking table.
To load MIRROR automatically, you should load MIRROR before any network drivers in the AUTOEXEC.BAT file.
