Release: SCO Unix ASC Universal Driver 2.3.5 Last Updated: 1/1/96 Copyright (c) 1995-1996 Advanced System Products, Inc. The AdvanSys SCO Unix Universal Driver supports AdvanSys SCSI Adapters for the SCO Unix 4.2 and OpenServer 5.0 Releases. The SCO directory includes the following files. The latest versions of these files are contained on the AdvanSys FTP and BBS sites. If the date listed in the SCO.TXT file is more than a few months old, please check the FTP or BBS site for a newer version of the driver. SCO.TXT This File SCOBTLD.EXE DOS Self-extracting Archive Containing Diskette Image SCOBTLD.Z UNIX Compressed Floppy Diskette Image To install the SCO Universal Driver you will need to create a Boot Loadable Diskette containing the driver. You may create the diskette using either a DOS or Unix system. Decide which system to use and follow the directions below. After the diskette is created it can be used to add the driver during an SCO Unix installation or used to add the driver to an existing SCO Unix system. Directions for both of these installation options are listed below. Supported Adapters ================== The CDB counts below indicate the number of SCSI CDB (Command Descriptor Block) requests that can be stored in the RISC chip cache and board LRAM. The driver detect routine will display the number of CDBs available for each adapter detected. This value can be lowered in the BIOS by changing the 'Host Queue Size' adapter setting.

It has no BIOS so it cannot control a boot device, but it can control any secondary devices. Instructions for creating the ASC Universal Driver Diskette from DOS ==================================================================== The file scobtld.exe is a self-extracting archive which contains an image of an SCO Unix EAFS file system. The image can be copied to a 3.5" diskette to make an ASC Universal Driver BTLD diskette. 1. Copy the file scobtld.exe to a DOS system. 2. Run the command scobtld.exe. The following two files will be created: btld.dat unixfer.exe 3. Insert a blank formatted diskette in the 3.5" floppy disk drive and create the diskette with the following command. unixfer btld.dat a: 4. To verify the contents of the diskette unixfer can also be run in reverse. The file btld.dat should exactly match test.dat. unixfer a: test.dat fc btld.dat test.dat Instructions for creating the ASC Universal Driver Diskette in SCO Unix ======================================================================= The file scobtld.Z is a compressed image of an SCO Unix EAFS file system. The image can be copied to a 3.5" diskette to make an ASC Universal Driver Diskette. 1. Copy the file scobtld.Z to an SCO Unix system. 2. Uncompress the file scobtld.Z with the following command in the same directory where the file is located. $ uncompress scobtld.Z 3. Insert a blank diskette in the 3.5" floppy disk drive and use "dd" to create the diskette with the following command. $ dd if=scobtld of=/dev/rfd0 bs=64k 4. To verify the contents of the diskette run dd in reverse. The file scobtld should exactly match test.dat. $ dd if=/dev/rfd0 of=test.dat bs=64k $ cmp scobtld test.dat Installing the ASC Driver during SCO Unix Installation ====================================================== 1. Set-up your devices to have the following SCSI Target IDs: Hard Disk: 0, CD-ROM: 5, and Tape Drive: 2. 2. Boot the system with the SCO installation boot disk. 3. Type "link" at the boot prompt. 4. The package to link to is "asc". 5. Insert the AdvanSys BTLD Diskette into the floppy drive when the system requests it. Note: The diskette should not be inserted after entering "asc". The install procedure will ask for it later. 6. At the end of the installation, you may be asked: "Do you want to replace 'auto' with 'asc' Y or N." Answer yes to the question. Installing the ASC Driver after SCO Unix has already been Installed =================================================================== 1. Run the command "installpkg" from the SCO Unix command line. 2. Insert the AdvanSys BTLD Diskette into the floppy drive. 3. After installation, type the following commands to rebuild a new kernel that contains the asc driver. For more information refer to the SCO documentation regarding compiling the kernel. cd /etc/conf/cf.d ./link_unix Installing SCSI Devices under SCO Unix ======================================= To create device files to access SCSI devices use the SCO "mkdev" command. "mkdev" is an interactive command that will ask you questions about your SCSI configuration, make kernel configuration changes, and re-build the kernel. Run "mkdev hd" for disks, "mkdev tape" for tape drives, and "mkdev cdrom" for CD-ROM devices. "mkdev" will ask the name of the AdvanSys driver and AdvanSys SCSI adapter number. The driver name is "asc" and adapter numbering begins with 0. If there is one AdvanSys adapter enter "0", a second adapter is number "1", etc. For disk devices "mkdev hd" should be run twice. The second time it is run after the kernel has been re-built and booted so that the disk can be partitioned and file systems can be built. The "mkdev" kernel configuration file is /etc/conf/cf.d/mscsi. It can be viewed with an editor to verify "mkdev" has added the correct parameters to the kernel configuration. Here is a basic list of SCO SCSI device files: Disk Device Files: /dev/[r]dsk/[0-9]s[0-9] Tape Device Files: /dev/[nruh]Stp[0-9] CD-ROM Device Files: /dev/[r]cd[0-9] AdvanSys Contact Information ============================ Mail: Advanced System Products, Inc. 1150 Ringwood Court San Jose, CA 95131 Operator: 1-408-383-9400 FAX: 1-408-383-9612 Tech Support: 1-800-525-7440 BBS: 1-408-383-9540 (9600,N,8,1) Interactive FAX: 1-408-383-9753 Customer Direct Sales: 1-800-883-1099 Tech Support E-Mail: support@advansys.com FTP Site: ftp.advansys.com (login: anonymous) Web Site: http://www.advansys.com
