ICON/NVL 386 for NW386 v3.0
Readme file for NW386 Supplemental Drivers
Overview
ICON/NVL 386 is a Novell certified NetWare Loadable Module (NLM)
for a NetWare 386 network. ICON/NVL 386 provides a shared memory
interface to a virtual disk environment in the ICON Intelligent
Disk Servers. Being a virtual environment, the NVL interface will
always provide a perfect disk to the Novell operating system. The
driver is identical across our entire family of Intelligent Disk
Servers. ICON/NVL 386 can be run with all generic NetWare 386
software.
Associated Files
Two files are on the ICON/NVL 386 diskette. The SMDISK.DSK file is
the NetWare 386 driver. STARTUP.NCF is included only as a sample
of a STARTUP file that can be created after the ICON/NVL 386 driver
is loaded.
Loading Instructions
SMDISK.DSK driver supports several different memory and interrupt
configurations as well as a Transactional Tracking System (TTS)
Option. After SERVER.EXE is loaded, the following command can be
issued at the network prompt:
load [path\]smdisk mem=<mem start add>:<mem blk size> int=<interrupt>
tts=<on/off>
Memory Location and Size
The first parameter is the memory location and size. A number of
memory locations are supported in the driver including several
locations in extended memory for the new 16 bit Target Cards. The
memory address must correspond to the RAM setting on the SMILE
Target card followed by a colon. The memory size, is entered in
hexidecimal numbers after the colon. The memory size is denoted as
shown below, according to the model number of ICON Target card:
8000 = 32K
10000 = 64K
20000 = 128K (for 16 bit Target Card)
The ICON/SMILE Target card comes in four different models.
The last three or four digits of the part number indicate the
model number:
810-032-002 = 64k only
810-032-005 = 64k only
810-032-006 = 32k or 64k options
810-032-006A = 32k or 64k options
For example, if the SMILE Target card's RAM address is D0000 and
the card is configured for 32K, the memory parameter following
SMDISK would be 8000. The command would be entered as:
load smdisk mem=d0000:8000
Interrupt Setting
Currently, four different primary interrupts are supported: 15, 10,
11, 12. These interrupts are represented to the driver by a
hexidecimal equivalent. If the SMILE Target card is configured
with interrupt 15 for example, the interrupt parameter following
the memory parameter would be int=f (hexidecimal f = decimal 15).
Likewise, with the card configured at interupt 11, the entry would
be made as int=b (hexidecimal b = decimal 11).
load smdisk mem=d0000:8000 int=f
TTS Option
ICON/NVL 386 supports Novell's Transaction Tracking System (TTS)
feature on all systems. Turning the ICON/NVL 386 TTS option on
(which is the default setting) turns off the ICON Intelligent Disk
Server cache and allows all writes to go directly to disk.
Currently, there is no way to distinguish a TTS write from a
regular write, so with the ICON/NVL 386 TTS option on, all writes
will go directly to disk. As a result, performance will decrease.
Turning TTS off will allow the data to be written to the disk
server cache memory. The system will perform faster, however,
there are data loss risks introduced if power to the disk server
was lost. Therefore, we recommend that a UPS be installed with the
Intelligent Disk Server. NetWare 386 version 3.1 will provide a
special flag for TTS writes which will allow ICON/NVL 386 to
distinguish between writes. To turn TTS off, the parameter tts=off
should follow the interrupt parameter when the LOAD SMDISK
command is issued. Please note that Novell's TTS feature will
continue to function under either option.
load smdisk mem=d0000:8000 int=f tts=off
Once the LOAD SMDISK command has been executed, the driver will
notify NetWare of the number of available drives and a prompt will
be displayed on the file server monitor. The 'load INSTALL' command
can then be executed to perform the normal disk and volume operations.
The INSTALL NLM will allow the installer to configure a STARTUP.NCF
file so that manual loading of ICON/NVL 386 will not be necessary again.
Please note that when the "Create STARTUP.NCF" option under the
INSTALL NLM is used for the first time, the memory size parameter will
need to be added to the information displayed on the screen.
For details of the Target card installation and configuration refer
to the ICON/SMILE System Reference Manual, part # 170-015-001. Any
further questions concerning the loading and operation of the
NetWare 386 driver can be directed to Sanyo/Icon's Customer Service
