A preliminary (BETA2) release of the Windows NT 3.5 device driver is now available which can control both the CM-205MS and CM-206 CD-Rom drives. The driver will work with both the CM-250 and CM-260 Host Adapter cards. ***************************************************************************** Notice: If you are installing NT from CD, you must run the WINNT.EXE program located in the /I386 directory of the NT install CD. This is a DOS based program that will fully setup NT without requiring you to add CDROM driver support. Once NT is installed in this manner, add the CDROM driver per the instructions that follow. This problem will be corrected in a future version of the driver. ***************************************************************************** To install the driver, use the following procedure from the Windows NT DOS prompt: 1) After decompressing the 206_NT2.EXE file, copy the extracted files to the LMS206 directory, which you create, then run the INSTALL program. "C:\LMS206>INSTALL" 2) Using the Windows NT Setup Utility, add a SCSI device. Select 'Other' to install the driver from the directory that you created above. The Setup Utility will use the OEMSETUP.INF file to automatically create a Registry Entry for the CDROM device. 3) The system will need to be rebooted for the changes to take effect. ******************************************************************************* Notice: Use this pre-release device driver at your own risk, and be advised that the software is not a fully functional product at this time. TECHNICAL SUPPORT IS NOT AVAILABLE FOR THIS DRIVER. If you experience problems using this software, please complete the included BETABUG.TXT response form and fax it to 719-531-0168. ******************************************************************************* _______________________________________________________________________________ Setting Interrupt Jumpers: The driver will utilize a 'Polling' method unless directed to use Interrupts by the Registry Entry for the device. Polling is fine for casual usage however, data transfers can be slowed down if many tasks are executing at the same time. Using Interrupts will ensure that the CDROM device gets the needed CPU time to run as efficiently as possible. Use the following procedure to enable interrupts for the CDROM device(s): 1) Set the Interrupt Jumper on the Host Adapter Card to the desired level. 2) Make a Registry Entry under the Lms206Cdrom Drivers' key as follows: At HKEY_LOCAL_MACHINE\SYSTEM\CURRENT_CONTROL_SET\SERVICES \Lms206Cdrom\Parameters\Device0 At the Device0 Entry, add a value called DriverParameter. This is done by placing the highlighter at the Device0 entry and then selecting ADD VALUE at the registry EDIT menu bar option. 3) Edit the DriverParameter String using the following syntax: IRQx=15 where x is the device number 0, 1, or 2. If you have one Lms206Cdrom drive, use device number 0. 4) The system will need to be rebooted for the changes to take effect. The Registry Tree Entry will look something like this if all goes well: HKEY_LOCAL_MACHINE\SYSTEM\CURRENT_CONTROL_SET\SERVICES \Lms206Cdrom\Parameters\Device0 DriverParameter:REG_SZ:IRQ0=15
