The information in this article applies to:
• Microsoft MS-DOS operating system 5.0
• Microsoft MS-DOS operating system 5.0a
This article was previously published under Q77768
SYMPTOMS
Leading Edge has confirmed that the memory test option contained on
their Diagnostics Utility disk may cause the system to hang or lock up
after upgrading to MS-DOS version 5.0. Only a cold boot will restart
the machine.
WORKAROUND
To successfully run the Leading Edge memory test, HIMEM.SYS,
EMM386.EXE, and any other memory managers must be disabled and MS-DOS
must not be loaded into the high memory area (HMA).
MORE INFORMATION
The Leading Edge Diagnostics Utility disk is included with each
Leading Edge computer system. This disk offers several system,
hardware, and memory tests. The memory test is executed by pressing
the hot key (F2) from the main menu of the diagnostics utility. To use
the diagnostics utility, follow the directions provided in the system
documentation.
The memory test may hang the computer if a memory manager (such as
EMM386.EXE or HIMEM.SYS) is active or if MS-DOS is resident in the
HMA. To allow the diagnostic utility to run, remove all references to
memory management software (HIMEM.SYS, EMM386.EXE, and so on) and
reboot the computer. Once the diagnostics have been completed, return
the CONFIG.SYS and AUTOEXEC.BAT files to their original state.
