INSTALLING SEAGATE'S RLL PAIRED SOLUTIONS I. INTRODUCTION Seagate's ST11R controller and RLL drive package offers a complete RLL Paired Solution. This section of the database will assist you in the installation of your Seagate RLL drive and controller. Before beginning, please read through the entire section. Seagate provides partitioning software pre-loaded on the drive for drives over 32 formatted Mb. BEFORE YOU BEGIN... - Seagate RLL Paired Program disc drives are shipped to you already formatted with a small DOS partition. The programs necessary to install the drive are contained in that partition. You must supply the DOS* system programs. You will be prompted with display screens at each step in the installation process. Paired Program drives with formatted capacities greater than 32-Mb are shipped with software to access multiple partitions or partitions larger than 32 Mb. * DOS is a registered trademark of Microsoft Corporation - REFER TO THE MATRIX IN TABLE 1 FOR SEAGATE DRIVES SUPPORTED BY THE ST11R. - A printable README file, containing supplemental installation information, is included with the installation software and is accessible via the DOS system commands. - The ST11R is designed to be installed only with drives certified for RLL (2,7) data encoding. Use with Seagate drives designed for MFM-only data encoding will void your drive warranty. Even though an MFM drive may initially format correctly with an RLL controller, performance may degrade over time. Seagate assumes no liability for installation of an RLL controller with an MFM-certified disc drive. - Seagate disc drives do not require any preventive maintenance. The head/disc assembly is sealed and does not contain any user-serviceable components. Do not tamper with the sealed top cover. Doing so will void your warranty. - When transporting or shipping a drive, controller or system, please ensure that they are correctly packed in the original container and shipped via an air-ride carrier. - Installation Warning: Do not touch the board components or connectors without observing static-discharge precautions. A grounded wrist-strap is preferred. If that is unavailable, ground yourself by touching the metal chassis of the system before handling any components. Do not unpack the components until you are ready to install them in the system. - Do not install the ST11R controller and apply power without first removing the rubber strips from all connectors on the controller. These strips are conductive. Failure to observe this warning will void the controller's warranty and can cause serious problems in your system. ST11R Controller and Drive Compatibility The ST11R supports up to two (2) of the following drives: Table 1 Drive Formatted MB Cylinders* R/W Heads Sectors ST138R 32.7 615 4 26 ST157R 49.1 615 6 26 ST225R 21.0 667 2 31 ST238R 32.7 615 4 26 ST250R 42.3 667 4 31 ST277R 65.5 820 6 26 ST4144R 122.7 1,024 9 26 * Maximum cylinders per drive. Usable cylinders are reduced by: a) One (1) cylinder for drive geometry and defect information. b) One (1) cylinder for diagnostic area. c) One or more cylinders for alternate tracks. Alternate track assignment is only made if defects involve more than one sector on a track. Single sector defects are compensated for within the track on which they occur. Alternate track assignment is only made when installing a drive through the BIOS (e.g.,DEBUG,-G=C800:5) or with the INSTALLR installation program (see Section IV.). II. ST11R Controller Setup 1) Remove the ST11R from the protective covering and pull the conductive rubber strips from between the pins at the J1, J2 and J3 headers. These strips provide static-discharge protection during transit. FAILURE TO REMOVE BEFORE INSTALLATION CAN CAUSE SERIOUS PROBLEMS IN YOUR CONTROLLER AND SYSTEM. 2) Configure the ST11R: C8000h is the default BIOS address. If there is a board already installed at this address in you system, use the jumpers provided to change to another address. Locations A and B are the two pins toward the front of the system and D and C are the two pins toward the back of the system. Refer to the documentation provided with your system and other peripheral devices to determine if there is an address conflict. See Table I below. The ST11R has four possible starting addresses: Table 2 CONFIGURATION BIOS ADDRESS PORT ADDRESS No Pins Shorted C8000h (default) 320h - 323h Pins A-B shorted D0000h 324h - 327h Pins C-D shorted D8000h 328h - 32Bh Pins A-B & C-D shorted E0000h 32Ch - 32Fh When installing the ST11R in a system that does not contain any other hard disc controllers, all jumpers should be removed from the BIOS PROM address jumper. The ST11R is shipped with the correct configuration for one hard disc controller. When installing the ST11R in a system with the Seagate STO1 SCSI Host Adaptor, the ST11R must be configured at a lower BIOS address than the ST01. When installing the ST11R in a system already containing a hard disc controller, the ST11R must be jumpered at a higher BIOS address than the other controller. If you are not sure of the other controller's address, try one of the higher addresses for the ST11R (e.g.,D8OOOh or E0000h). 3). The J5 header on the ST11R may be used to provide disc drive power for systems lacking auxiliary power connectors. See your Dealer for cabling. Note: Some early configurations of the ST11R may not include the J5 header. J5 is pinned out as follows: Pin Signal Description 1 +12 VDC + 12 Volt DC Supply 2 +12 VDC + 12 Volt DC Supply 3 +5 VDC + 5 Volt DC Supply 4 GND Pin removed for connector key 5 GND Ground 6 GND Ground Note: Pin 1 is toward the from and top of the system and also indicated by a square solder through pad on the ST11R. III. Drive Configuration And Installation Prior to installation, rest the drive on a padded anti-static surface; never on an unprotected hard surface. Do not touch the board components or connectors without observing static- discharge precautions. A grounded wrist-strap is preferred. If that is not available, ground yourself by touching the metal chassis of your system before handling any components. VERIFY THAT THE POWER IS OFF. Remove the top cover from your system. Access to the top cover screws is via the back of the system. Save the screws. 1) Drive Select Jumpers: 2) Installation of one drive requires a jumper at its Drive Select 1 position. Note: Drive select 1 is selected by shorting the 2 pins closest to where the 20 pin connector plugs into the drive. With one exception, noted in bullet 4 below, the second drive must have its Drive Select jumper at the DS2 position. Drive select 2 is one set of pins over from the drive select 1 position. Note: Check that there also is a jumper installed at position 7 on the Drive Select header. There should be only two jumpers installed at the Drive Select header. 3) Drive Resistor Termination Packs: If you are installing a single drive, the resistor termination pack must remain installed. If you are installing two drives, remove the pack from the drive connected at the middle of the 34 pin cable. When installing the resistor termination packs, note that pin-1 is designated by a dot or number 1 on the pack. A square pad on the PCB indicates pin-1 at the socket. 4) Drive Cables: J1: With one exception, the first (or only) hard drive attached to the ST11R will be Drive Select 1 ("C") and the second, Drive Select 2 ("D"). Mate the J1 (the large ribbon cable) connector on the "C" drive to the connector at the end of the cable. Connect J1 on the "D" drive (if it exists) to the middle connector on your cable. Note: J1 - Pin 1 on the ST11R is toward the front of your system and is also indicated by a square solder through pad. J2: Connect the 20-pin connector (the small ribbon cable) on Drive "C" to the J2 connector on the ST11R. Connect the 20-pin connector on Drive "D" (if it exists) to the J3 connector on the ST11R. Note: J2 is the 20 pin connector at the top of the ST11R and in line with J1, the 34 pin connector. Pin 1 on both J2 and J3 is toward the front of your system and is also indicated with a square solder through pad. Note that for all connections, pin-1 on the controller corresponds to pin-1 on the drive. Some cables have a contrasting-color strip on one wire to indicate pin-1. EXCEPTION: If there are two drives installed, and the common ribbon cable (the cable between the two drives) has a set of 5 wires that are split and twisted off at one connector, then both drives must be set as Drive Select 2. Your software will still recognize the drives separately as Drive "C" and "D". Remove the resistor pack from the drive in the middle (closest to the controller) of the cable. 5) Install the controller in one of the expansion slots on the motherboard in your computer. Note: Do not use the expansion slot that is closest to the power supply in your system. 6) Mount The Drive: If possible, install the drive in the left bay (viewed from the front of the system), as the power supply may obstruct the cables. For ease of installation, attach J1, J2 and the power cable before you slide the drive completely into position. Minimum required for mounting: 4, 6-32 UNC-2B X 0.31-inch screws. Tighten the screws down evenly to 8 +/-.8 inch-lbs. OVERTIGHTENING OR USING SCREWS THAT ARE TOO LONG MAY CAUSE DRIVE DAMAGE. 7) Verify that all connections are correct and replace the system cover. Go to Section IV. for the required formatting operation. IV. Preparing The Drive The installation process will low-level format new physical blocks, create DOS-compatible partitions, root directories and file allocation tables for the entire drive. This procedure is identical for IBM XT* and AT* systems, except where indicated. *XT and AT are registered trademarks of International Business Machines Corp. All drives are shipped with a small DOS partition containing INSTALLR.EXE, PARK.EXE and README.1ST (a printable supplement to this installation guide). README.1ST will contain the latest installation information for the drive being installed and can be accessed by the DOS system commands: TYPE, COPY or PRINT (i.e. A>type C:readme.1st). Drives having more than 32 formatted megabytes are shipped with partitioning software, referred to as Disk Manager*. This software supports multiple DOS partitions on a single drive and partitions greater than 32 Mb. A number of reference files (.REF) provide additional information concerning the partitioning process. These files can be accessed by DOS system commands: TYPE, COPY and PRINT. *Disk Manager is a registered trademark of Ontrack Computer Systems. IF YOUR DISC HAS LESS THAN 32 FORMATTED MEGABYTES, you will need one DOS- bootable diskette that has the boot files from the version of DOS that you plan to use on your Seagate drive. This diskette should also contain the FORMAT program provided with your DOS system, and sufficient space (approximately 50-Kb) to save the installation programs from the hard disc. The diskette must not be write-protected. If your disc drive has more than 32 formatted megabytes, you will need two diskettes to complete the installation process. Only one diskette must be DOS-bootable with the version of DOS that you plan to use. The second diskette must have at least 320-Kb available to save the installation and Disk Manager programs. The diskettes must not be write- protected. IMPORTANT INFORMATION FOR PC AT INSTALLATIONS: - If you are installing your drive in a PC AT or compatible machine and a standard hard drive is not presently attached or operational, the hard drive count in CMOS RAM will already be set to zero. It is not necessary to change the CMOS RAM drive count when installing Seagate paired program drives. - If a hard drive is already attached and operational in your system, it will be the first drive and the Seagate paired drive will be the second drive. It is not necessary to change the CMOS RAM hard drive count when installing Seagate Paired Program drives. If you are installing a second hard drive in your system and Disk Manager is used, it is important that the Disk Manager driver (DMDRVR.BIN) is loaded on the boot drive and a "device = DMDRVR.BIN" statement is contained in the CONFIG.SYS file on that drive. Normally this statement should follow any "device =" statement for the boot drive. WARNING TO INSTALLERS AND/OR SECOND DRIVE INSTALLATIONS: DOS assigns a logical identifier (C,D,E...) to each partition that it recognizes during the boot load. DOS assigns identifiers to the first partition on each physical drive before assigning identifiers to additional partitions. Therefore, if you have a single drive with three partitions, they will be assigned C,D and E. However, if a second drive is installed, the first partition on drive 1 will be assigned C, the first partition on drive 2 will be assigned D, then E and F will be assigned to remaining partitions on drive 1. Any additional partitions on drive 2 will be assigned subsequent identifiers. It is important to note that the partitions previously identified as D and E will change when the second drive is added. The PARK program supplied with your drive is required only to park the read/write heads for the ST238R. Always park the read/write heads before your drive/system is transported. All other Seagate drives feature automatic head-park when the power is removed. Software Installation Procedure: 1) Place a DOS-bootable diskette* in drive A and switch the power on. If you have correctly installed the drive and controller, "ST11R Hard Disc Installation Vx.x" will be displayed, followed by a screen prompting you to the next step. Each step in the process is lead by screen prompts. For specific DOS questions, refer to the DOS manual supplied with your system. * The DOS bootable diskette must have the boot files from the version of DOS that you plan to use with your Seagate drive (Do not mix DOS versions). The FORMAT program provided with your DOS operation system and sufficient space (50kb) to save the installation programs stored on the drive. This diskette must not be write protected. 2) After the boot process is complete, begin the installation by typing: C:INSTALLR C, or if you are installing a second hard drive, D:INSTALLR D. 3) If you are installing a Paired Program drive with more than 32 formatted MB, you will be instructed to remove the DOS diskette and insert a blank diskette* to make a backup copy of the Disk Manager software. * This second diskette must have at least 320Kb available to save the installation and Disk Manager programs stored on the drive. This diskette must not be write protected. If you are installing a drive with Disk Manager and you already have a hard disc drive in your system, you must copy the DMDRVR.SYS and CONFIG.SYS files from the Disk Manager diskette to the existing (first) drive. If you already have a CONFIG.SYS file on the boot disc, update the file to include the line "device = DMDRVR.BIN". Refer to your DOS manual for instructions on editing your CONFIG.SYS file. The Disk Manager software will assist you during the remainder of the format process with screen prompts. If you prefer, you may use the partitioning and high level formatting software supplied with your DOS system (FDISK and FORMAT). If you select this option during installation, the installation software will perform a low-level format of your drive before exiting to DOS. 4) The entire software installation routine is menu-driven and takes from ten to thirty minutes, depending on drive size. After the format is complete the read/write heads will be parked. At next power-up the system will boot from the hard disc. V. Alternate Drive Formatting Method To format a new hard disc, or reformat a drive, follow the procedure noted below. You will need: - Your DOS diskettes and documentation - Use the same version of DOS throughout the formatting operation. - The defect list that was shipped with the drive. Note: Some drives are shipped with the defect list fixed to the drive top cover. 1) Load a DOS-bootable diskette in drive A and turn the power on. 2) Once the boot process is complete, load the DOS diskette that contains the DEBUG.COM program (usually found on the "DOS Supplemental Programs" diskette) and type "Debug" followed by return at the A> prompt. When DEBUG responds with the "-" prompt, type g=C800:5 followed by return. Additional instructions will appear on your screen. Note: If you changed the BIOS address from the default setting (see Section II.) you will need to type a different value in place of C800:5 (i.e. D000:5). VI. Disk Manager 1) Insert your DOS diskette in Drive A and turn the power on. 2) At the "A>" prompt, load your copy of Disk Manager in drive A and type "DM" followed by return. Follow the instructions on the screen. Help is available throughout the program by pressing the F1 function key. VII. Troubleshooting Your Installation If you have a problem getting the initial screen or later getting the system to boot: - Check the cabling between the controller and the drive: Pin-1 on the controller corresponds to pin-1 at the drive. The contrasting color strip on the cable should be attached to pin-1. - Check the power cable on the drive. When power is applied, you should be able to hear the drive motor. - Verify that the Drive Select jumper at the drive is set correctly. - Verify the BIOS addresses on the ST11R. If you have more than one disc drive or tape controller that uses BIOS ROM space, each must be configured to operate at a different memory address. Addressing multiple controllers at the same memory location can cause problems of a seemingly indeterminate nature. If you suspect this type of problem, turn off the power to your computer, remove the controller and change the jumper setting. Refer to Section II. - If you experience problems accessing your DOS partition after installation, refer to the .REF files provided with the Disk Manager software for additional information regarding deviations in hardware and DOS systems from various suppliers.
