1. Description of NetWare DOS Requester Software
The NetWare DOS Requester consists of a number of files that
provide NetWare support for a DOS client. Unlike previous
versions of the NetWare DOS client, the Requester is built on
a number of Virtual Loadable Modules (VLMs). The VLM.EXE (VLM
manager) is responsible for loading the required modules.
NOTE: The NetWare DOS Requester is NOT compatible with
NETX.COM or NETX.EXE. Use NETX.VLM for compatibility with
shell calls.
The following table lists the current core modules in their
default load order. The table also includes descriptions,
default values, and flags indicating whether the module is
"Required" or "Optional" for each of NetWare Directory
Services or bindery services.

2. NEW NET.CFG PARAMETERS Since the VLMs 1.10
A> CONFIRM CRITICAL ERROR ACTION = ON|OFF {default is ON}
Previously in Windows, critical errors may have been intercepted by Windows
before the VLMs received the critical error. If the user entered CANCEL after
receiving, the Windows error "Cannot read from device network--
Cancel--Retry", Windows would proceed to tear the connection to the server
down without user intervention or notification.
This new net.cfg parameter will intercept the INT 24 (critical error), and
allow the user to "Retry" manually, before the connections are torn down.
For this parameter to work, the NETWARE.DRV v3.03 must be loaded (WINDR1.EXE).
Make sure to have the following in the SYSTEM.INI file:
[boot]
network.drv=netware.drv
B> EOJ = ON|OFF {default is ON}
Previous versions of the VLMs would not parse this parameter.
This version of the VLMs will now parse the EOJ = ON|OFF NET.CFG parameter.
This option will turn the end of job automatic closing of files, locks,
semaphores, and so forth, ON or OFF. This supports EOJs from a DOS INT 21 D6
function call.
C> FORCE FIRST NETWORK DRIVE = ON|OFF {default is OFF}
Previously, if you typed logout from any drive other than a local drive or
the FIRST NETWORK DRIVE, the SYS:LOGIN drive would be mapped to the drive
letter you logged out from.
If set to ON, this parameter will force the SYS:LOGIN drive to be mapped to
the "FIRST NETWORK DRIVE = ?" drive upon logout.
D> LIP START SIZE=xxx {default is 0, min is 576, max is 65535, 0 is off}
This parameter was provided for those that operate across mulitple hop routes,
with one segment of the connection that has smaller packet sizes than the local
routes, but larger than the minimum packet size of 576 bytes. This improved
algorithm improves performance while drastically improving thruput.
E> LOAD LOW FIO=ON|OFF {default is OFF}
FIO.VLM now can be loaded low (In conventional or UMB memory). This
increases performance for repeated reads and writes, such as with database
applications
To load the transient portion of FIO.VLM into conventional or UMB memory,
add the following parameter to the workstation's NET.CFG under the NETWARE DOS
REQUESTER heading:
LOAD LOW FIO = ON
F> LOAD LOW NETX=ON|OFF {default is OFF}
NETX.VLM now can be loaded low (In conventional or UMB memory). This
increases performance for repeated reads and writes, such as with database
applications
To load the transient portion of NETX.VLM into conventional or UMB memory,
add the following parameter to the workstation's NET.CFG under the NETWARE DOS
REQUESTER heading:
LOAD LOW NETX = ON
G> LOAD LOW REDIR = ON|OFF {default is OFF}
REDIR.VLM now can be loaded low (In conventional or UMB memory). This
increases performance for repeated reads and writes, such as with database
applications.
To load the transient portion of REDIR.VLM into conventional or UMB memory,
add the following parameter to the workstation's NET.CFG under the NETWARE DOS
REQUESTER heading:
LOAD LOW REDIR = ON
H> LOCK DELAY = xxx {default is 1, min is 0, max is 255}
This version of the VLMs will now parse this parameter. The "Lock Delay"
determines the delay between LOCK RETRIES. The delay value determines the
number of 64 KB empty loops to execute between RETRIES. This parameter is
dependant on processor speed. Faster CPUs will execute a 64 KB no-op loop
faster; therefore, they may need to have this parameter increased.
I> LOCK RETRIES = xxx {default is 3, min is 0, max is 255}
The "Lock Retries" determines the number of retries that are executed if a
SHARE violation/failure occurs when opening or locking a file.
CHANGES TO NET.CFG PARAMETERS Since the v1.10 VLMs
A> READ ONLY COMPATIBILITY = ON|OFF {default is OFF}
In previous versions of the VLMs, READ ONLY COMPATIBILITY defaulted to ON.
The default was changed to make the VLMs consistent with NETX.EXE v3.32.

3. NET.CFG File Parameter for the NetWare DOS Requester Option
The following table lists the parameters for the various
modules of the NetWare DOS Requester.
The following list is complete. Any parameters which may
have been used previously by the NetWare DOS Requester but are
not listed here are invalid.

pre-initialization time.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
