Installing OS/2 Warp Server on OS/2 Warp 4

4.5 Cache for the HPFS386 File System

This is only valid for the OS/2 Warp Server Advanced.

Edit your CONFIG.SYS and add the CACHE386.EXE statement below, then reboot the system.
```
RUN=X:\IBMLAN\NETPROG\CACHE386.EXE
```
Where X: is your server drive.
Save and close your CONFIG.SYS.

If you do not add this line to your CONFIG.SYS, you will get the following error whenever you start the File and Print server:

Net 3091: the CACHE386.exe is not running, The server cannot be started.

You can start CACHE386.EXE manually from a command prompt. However, it is recommended that you edit the CONFIG.SYS and add the above statement.
