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=: int= tts= 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.
