> This is part of the installation of the server:
> 
> The installation program sets the useallmem parameter to yes to maximize performance for the 386 HPFS component of File and Print Sharing Services.
> 
> OS/2 Warp Server Installation checks for known network adapter cards that cause problems with the useallmem set to yes and resets it to
> no if problems are detected. 
> 
> Problems might occur with network adapter cards that have busmaster capability but do not support full 32-bit DMA. The behavior of a network adapter card that does not support 32- bit direct memory access (DMA) is described below. 
> 
> Frequently, a session can be established with the server if such network adapter cards exist and are not detected or if a 32-bit DMA card is installed in a 16-bit slot. 
> 
> However, unpredictable errors might occur because the network adapter cannot access memory above 16MB, but the server sometimes places network data in memory above 16MB. 
> 
> Should this occur, communication between the server and the workstation is impossible. 
> 
> After installation, you might receive the error message SYS0058 if the server cannot perform a network operation.
> 
> If you type Net Error at the
> workstation, NET3195 is displayed and says that you have a NetBIOS Control Block (NCB) error.
> 
> This occurs when you issue either the DIR or COPY command, your network adapter does not support 32-bit DMA, and useallmem is set to yes. If you type Net Error at the server, it shows no errors. To
> correct this situation, edit the /IBMLAN/IBMLAN.INI and /IBM386HPFS/ HPFS386.INI files and set useallmem to no.
> 
> Then run the OS/2 Warp Server Tuning Assistant to calculate a new value for cachesize= in the /IBM386FS/HPFS386.INI file. 
> 
> Performance might be reduced if the
> Advanced File and Print Sharing Services must support many active users , but its performance will be acceptable in some situations.
