Optimize the controller performance I). Windows NT 4.0 Fresh Installation Instructions. ======================================================= Follow the instructions in this section if you are performing a fresh installation of Windows NT 4.0 using CMD controller. You can either install Windows NT from floppies or CD (Also refer to note 3 for additional details.) 1. Enter the system bios and setup the device bootable priority. For more information, please refer to your system board's user manual for reference. 2. Save the system configuration. 3. Insert CMD IDE controller. Refer to Note 2 of this document for detail. 4. Insert the NT4 CD into the CD-ROM drive and reboot. 5. If you choose to install Windows NT from floppies, insert the Windows NT Disk1, also known as boot disk, into the floppy drive for the floppy installation. 6. When you see this message, "Windows NT Setup" screen, press the F6 function key. 7. When prompted, select the option S to specify additional device 8. Highlight other and press enter. 9. Put the CMD driver diskette into drive A: and press the 'enter' key. 10. The screen displays the adapter driver support on the diskette. The "CMD CSA-64xx IDE Driver" is highlighted by default; press enter. 11. If you want to add additional host adapters, do so at this time by repeating step 7 for each host adapter and insert the manufacturer's driver diskette. Otherwise, Press enter to continue with the Windows NT installation. 12. For the remainder of the installation, please follow the NT SETUP screens' instructions. 13. After NT installation is completed and ready for use, re-insert the CMD's device driver diskette into the floppy drive. Change to the WINNT directory then copy the CMDCFGNT.EXE file from the floppy disk to the " \WINNT\SYSTEM32 " directory. This file will enable you to fine tuning the CMD IDE chip for optimal performance. II) Adding CMD host adapter in an existing Windows NT platform =============================================================================== Notes: The CMD driver MUST be installed before switching to CMD IDE controller for existing Windows NT 4.0 system. =============================================================================== 1. Go to the Control Panel and select the "SCSI Adapters" icon. 2. Select the "Drivers" tab and click on the "Add" button. 3. Click on the "Have Disk" button, insert the driver diskette provided by CMD. 4. From the "Install From Disk" dialogue box, type A:\WINNT and click ok. 5. Select the "CMD PCI 646U2/648/649 Ultra DMA IDE Controller" from the "SCSI Adapter" screen and click ok. 6. When prompted to reboot, you must reboot for the new changes to take effect. 7. Shut down the system and install the CMD IDE controller to a PCI bus master slot. Refer to Notes 2 of this README file for reference. 9. Turn on your system and the NT operating system should be functional with the CMD IDE controller . (If the system fails with a blue screen with the third line from top say "Inaccessible_boot_device," then CMD driver is not properly loaded in the previous steps.) 10. Reboot NT and try to restart with the last known good configuration then go back to step 1 to reinstall the CMD driver again. To return to the last know good configuration setting, press the Space bar when booting NT and press " L " then RETURN. III). Optimize the Controller's performance ============================================= The following steps are optional, for those who are interested in getting maximum performance. 1. Open the CMD configuration utility by performing the following steps: a). Press the START button from the tool bar and select run. b). Type CMDCFGNT.EXE and press ENTER 2. By the default, the CMD device driver will set the PCI Bus speed to 33 MHz and the DMA enable button is enabled in the "General Tab" option. If you wish to change to some other values, you can alter them in this property page. 3. The controller #, next tab, (e.g. # = 0, 1,and so on) allows you to selectively tune each drive in a channel of a particular CMD controller. For example: ============ Let's tune secondary channel slave drive to operating at UDMA mode 1. Go to the secondary channel override dialogue box, put a check for the slave box. Next, click on the UDMA button. Then, pull down the menu to select 1. Click OK and reboot the system. Notes: ====== 1. Install the CMD driver before switching IDE controller for Section "II." 2. Power off the system and connect hard drives and CD-ROM drives to the CMD IDE controller. Install it to the PCI slot that supports bus master. Enter system CMOS setup and clear the hard drives configuration to "NONE" or "AUTO." Also, if the BIOS set up has the features for booting from an add-on card, please select it. SAVE and EXIT CMOS. 3. The current CMD option ROM is not fully functional with the latest 8x0 chipset to complete a fresh installation of the NT operating system. CMD is currently discussing this issue with Intel's support engineers. Therefore, if you have the latest Intel 8x0 chipset, please follow the section II to add the CMD controller.Download Driver Pack
