Understanding the NetWare Client Software
The NetWare DOS Requester Architecture
applications.
• Takes advantage of memory-swapping technology and DOS redirection
capability.
• Includes the Packet Burst protocol and Large Internet Packet (LIP) support.
• Supports the installed base of NetWare users by providing backward
compatibility with NETX.
• Supports the NetWare Directory Services architecture in NetWare 4 software.
File and Print Services
Previously, the NetWare Client shell for DOS intercepted requests for DOS
services. At the client workstations, the NetWare shell (NETX) software
hooked interrupts in front of DOS and provided network services for files
and printing.
The NetWare DOS Requester takes advantage of DOS redirection to provide
file and print services. It also uses NetWare shell technology to add features
to DOS and provide compatibility with applications that run on the NetWare
shell software.
Memory Usage
The NetWare DOS Requester works with extended memory, expanded
memory, and conventional memory. When loading in extended memory, the
Requester loads in LIM XMS 2.0 memory, not in the High Memory Area
(HMA), meaning that extended memory can coexist with DOS loaded high.
The VLM.EXE program automatically selects the best possible memory
use: extended memory first, expanded memory second, and conventional
memory only in the absence of enhanced memory options.
