******************************************************* * Infortrend PCI RAID Controller Series * * Drivers and Utilities for SCO OpenDesktop 3.2.4 * ******************************************************* Version: V1.3 Dear Infortrend customer, In this directory: SCOV13.Z - Driver diskette image for SCO OpenDesktop 3.2.x The driver and utility can be applied to the following operating systems: SCO OpenDesktop 3.2.4 It cannot be applied to SCO OpenServer 5. For installing the driver for SCO OpenServer 5, please refer the directory \2101\SCOOS5. How to Make the Installation Diskette from the Disk Image File -------------------------------------------------------------- You may find some of the files in this directory have the same filename but with different filename extension. They are the same disk image but one of them is compressed for easy file transferring: 1) With no filename extension: This is the disk image made of unix "dd" command. To restore this disk image onto a floppy diskette, use "dd" command: # dd if=filename of=/dev/fd0 bs=1440k (where "filename" is the filename of the uncompressed disk image, "/dev/fd0" refers to the device name of the floppy drive.) 2) With filename extension ".Z": This is the disk image made of unix "dd" command, then compressed by unix "compress" command. To uncompress the compressed file, use the unix "uncompress" command: # uncompress filename.Z (where "filename.Z" is the filename of the compressed disk image. After the file has been uncompressed, the filename extension will be removed. The "filename.Z" will become "filename".) The compressed file - "filename.Z" will become uncompressed - "filename". To restore this disk image onto a floppy diskette, use "dd" command: # dd if=filename of=/dev/fd0 bs=1440k (where "filename" is the filename of the uncompressed disk image, "/dev/fd0" refers to the device name of the floppy drive.) The disk image files require a floppy drive equipped unix system to restore to a floppy diskette. Some unix systems might not have the CD-ROM drive, we provide both compressed and uncompressed disk image files for easy file transfer between two systems. Label the Installation Diskette(s) ---------------------------------- 1. Please refer to "How to Make the Installation Diskette from the Disk Image File" section above to create the floppy diskettes for installation. 2. Please label the diskette made of "SCOV13" as: +-------------------------------------------------+ | Infortrend IFT-2101U PCI RAID Controller | | | | SCO OpenDesktop 3.2.4 | | BTLD Drivers | | | | Version 1.3 | | (Code: SCOV13) | +-------------------------------------------------+ Install IFT-2101U/2101U2 Driver During Installation of SCO OpenDesktop 3.2.4 ---------------------------------------------------------------------------- ** Important ** A. ALWAYS CHANGE THE CACHE TO WRITE-BACK DISABLED BEFORE INSTALLING OPERATING SYSTEMS AND PARTITIONING. IFT-2101U/2101U2 is a high performance PCI RAID controller with Write-Back cache enabled. During the installation of some operating systems, the installation program might reset the computer automatically while the cache still contains data not yet written to the drives. It might cause the installation or partitioning failure. To avoid the failure, always switch the cache mode to Write-Back DISABLED (Write- Through mode) before changing the drive partition (e.g. using DOS FDISK) and before installing any operating systems. B. HOW TO CHANGE CACHE MODE TO WRITE-BACK DISABLED? Using BIOS Text RAID Manager (PC platform only) to disable the Write-Back Cache. Power on the computer, press when the Infortrend information appears. Choose "Configure RAID" from the menu and press to enter a proper display mode (either ANSI, VT-100 or ANSI Color). In the Main Menu, choose "View and Edit Configuration Parameters", then "Caching Parameters". A sub-menu contains "Write Back Cache Enabled/Disabled" which refers to the Write Back mode is Enabled or Disabled. Press on it and choose "Yes" to change it. After the cache mode changed, it is a must to reset the computer to take affect the new setting. After the driver partitioning and operating system installed, using the same procedure to enable the Write Back cache, the high performance Write Back Caching will bring your system into a higher performance level. 1. Insert the Boot Disk of SCO OpenDesktop 3.2.4 into the floppy drive, power on the system and boot from the floppy. 2. While the system boot up with the prompt "boot:", enter "link" to load BTLD driver during the installation. Enter "ift2x" as the package name of the driver. boot: link ift2x 3. Follow the on screen instruction to complete the installation. Install IFT-2101U/2101U2 Driver to an Existing SCO OpenDesktop 3.2.4 -------------------------------------------------------------------- 1. Insert the driver diskette into the floppy drive and mount it. # mount -r /dev/fd0 /mnt where "/dev/fd0" refers to the floppy drive, "/mnt" is the directory where the floppy mounted to. 2. Under the command prompt, use "btldinstall" to install the driver. Enter the driver name "ift2x". # btldinstall /mnt 3. After the driver installed, relink the unix kernel. # cd /etc/conf/cf.d # ./link_unix How to Configure RAID in SCO OpenDesktop 3.2.4 ---------------------------------------------- There is no Text RAID Manager available for SCO OpenDesktop 3.2.4. To configure RAID, please use the Text RAID Manager in DOS. ******************* Product/Update Information ******************* For more information about Infortrend and our RAID controller products, please visit our web site: http://www.infortrend.com.tw or http://www.infortrend.com To download the latest firmware and drivers/utilities, please visit our ftp site: ftp://ftp.infortrend.com.tw or ftp://ftp.infortrend.com ******************** Support Information ************************ If you have any technical questions regarding to your RAID system, please contact your RAID system supplier first, they will provide the latest information and sincere support. ******************** Suggestions?
