SUBJECT:

EMM386 memory issue under DOS.

QUESTION:

DOS EMM386 needs to avoid DC00:0 and the manual should explain this.

ANSWER:

This occurs only on the PC card. A PC card must use some memory for driver space.  By default our wireless PC card uses the memory between DC00-DCFF.  So, if you want to use EMM386, you should use the following command in the CONFIG.SYS file to prevent conflict:

DEVICE=EMM386.EXE X=DC00-DCFF

Note:  It is not recommended that you use EMM386 when you use NetWare client's VLM.EXE or NETX.EXE shells. It seems there exists a compatibility problem between EMM386 and NETX.EXE (or VLM).

In addition, by default the NET.CFG for PCMCIA uses DC00 for driver memory space.  If you want to use the DC00 memory segment with your specific controller or interface card, you must modify the 'MEM DC00' line in theNET.CFG by replacing 'DC00' with another address, e.g. CC00, CD00, CE00, CF00, D000, ... , DF00.
