DEVICEHIGH Uses UMB from Previous DEVICEHIGH Command (103521)
The information in this article applies to:
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.22
This article was previously published under Q103521
SUMMARY
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
and filenames.
SYMPTOMS
If you have a DEVICEHIGH statement without an explicit /L parameter,
MS-DOS uses the same upper memory block (UMB) as the last DEVICEHIGH
command that did have an explicit /L parameter. For example, if you
have the following commands in your CONFIG.SYS file, RAMDRIVE.SYS
loads into region two:
devicehigh/l:1=c:\dos\ansi.sys
devicehigh/l:2=c:\dos\dblspace.sys
devicehigh=c:\dos\ramdrive.sys
If you remove the DEVICEHIGH command for DBLSPACE.SYS, RAMDRIVE.SYS
loads into region one.
NOTE: This example assumes both UMBs are large enough to hold
RAMDRIVE.SYS.
