The 3C589D PC Card requires 4 K for the CIS memory for normal operation (when you are running diagnostics, the PC Card needs 8 K of memory).

The 3C589D PC Card searches the upper memory, finds the 4 K block that has been excluded, and uses this area for reading the contents of the CIS memory. For this reason, you do not need to exclude a specific range, as long as it is contiguous.

Follow these steps to exclude a sample 4 K memory range:

1Make a backup copy of the CONFIG.SYS file. Type: copy config.sys config.old [Enter]

2Use a text editor to edit the CONFIG.SYS file on your PC.

3Exclude the memory range that the 3C589D PC Card is using. For example, type this line in the CONFIG.SYS file:

device=c:\windows\emm386.exe noems x=DE00–DFFF

where x stands for exclude, followed by the memory range that the PC Card is using. In this example, the memory setting is DE00–DFFF. This is only a sample.

Refer to the manual that accompanied the memory manager software for additional instructions and information.

4Save the CONFIG.SYS file and exit the text editor.

5Reboot the PC.

The procedure for avoiding conflicts with a memory manager is completed.
