Disk Errors with EMM386.EXE on Laptop Computers

If your laptop has a "suspend/resume" feature to save power, you mayreceive error messages similar to the following with MS-DOS EMM386.EXEversion 4.45:
  • Serious disk error has occurred

  • Segment Load Failure (in Windows-based applications)
This error is usually caused by an interaction between the laptoppower manager feature and EMM386.EXE.
To work around this problem, do the following:
  1. Try to determine if there is a region that needs to be excluded from upper memory blocks (UMBs) to allow the laptop power management to work with EMM386.EXE version 4.45.

    This information may be available in your laptop manual. As an alternative, you can exclude the A000-EFFF memory range to test for a UMB conflict. For example:
    device=c:\dos\emm386.exe noems x=a000-efff
  2. If the problem occurs only with MS-DOS 6 EMM386.EXE version 4.45 and cannot be corrected with the above step, use the version of EMM386.EXE that came with the laptop.

    NOTE: If you do this, you cannot use MemMaker.
  3. Remove EMM386.EXE to see if the problem is related to using EMM386.EXE.

The following changes may be needed on a Safari 386 Notebook afterinstalling MS-DOS 6.0 or 6.2 and running MemMaker:
  1. Revert to the Windows version 3.1 EMM386.EXE file.
  2. Exclude the A000-C7FF range by adding the following to the CONFIG.SYS file:
    device=c:\windows\emm386.exe x=a000-c7ff
Do not use EMM386.EXE version 4.45, and do not add HIGHSCAN or NOEMSstatements to the DEVICE line for EMM386.EXE (in your CONFIG.SYS file).The Safari product included here is manufactured by a vendorindependent of Microsoft; we make no warranty, implied or otherwise,regarding this product's performance or reliability.
