SYMPTOMS
If you use the new MS-DOS 6.0 and later LOADHIGH (LH) parameters (/L or /S) with a third-party command interpreter (sometimes called a shell), such as NDOS or 4DOS, you receive the following error message:

Error: Unknown Command &quot;/l: ; &quot;



CAUSE
MS-DOS 6.0 and 6.2 COMMAND.COM supports two memory specific parameters: /L and /S, which are determined by MemMaker. For example, &quot;LOADHIGH /L:0;1 MOUSE.COM&quot; is a valid command in MS-DOS 6.0 and 6.2.

Third-party command interpreters such as 4DOS and NDOS are designed to replace COMMAND.COM. These command interpreters have to be updated to work correctly with the new /L and /S parameters.



WORKAROUND
To work around the problem, either use COMMAND.COM for your command interpreter or remove the /L and /S parameters from your LOADHIGH (LH) commands.

For more information or to obtain an update to your third-party command interpreters, please contact your command interpreter vendor.

The 4DOS and NDOS products included here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
