Jumper installed refers to the pin jumpered to the center pin. Combinations of jumpers E2, E3 and E4 can be made to determine a correct configuration. An explanation of the jumpers follows: Jumper E2 enables or disables chip select 1 (CS1). Installed enables it. Jumper E3 will clear IRQ14 with deassertion of Host SLV/ACT. Jumper E4 will clear IRQ14 with a status read only. Care must be exercised with the routing of the power & signal cables. They should not be routed next to the drive PCB or other high frequency or large current switching signals. Improper drive opera- tion can result from improper cable routing. ********************************************************************** I N S T A L L ********************************************************************** CONNER CP4044 PRODUCT MANUAL REVISION 1.7 AUGUST 1990 Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ Installation direction ---------------------- The drive may be mounted in any attitude! Recommended Mounting Configuration ---------------------------------- This drive is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger and heavier disk drives. The design features which allow greater shock tolerance are the use of rugged heads and media, a dedicated landing zone, closed loop servo positioning and specially designed motor and actuator assemblies. Eight base mounting points are provided to the customer. The drive is mounted using 6-32 x 3/16" max. screw insertion for the bottom or M3 x .05-6H x 4 mm screws for the sides. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. For additional vibration isolation, an external suspension system may be used. Power Connectors ---------------- DC power is provided on the 44 pin interface connector. The recommended mating connector is AMP part number 1-487620-9. DC power may also be supplied to the drive through 3 pins on the 12 pin Serial I/O connector. The recommended mating connector is Molex part number 39-01-0033 utilizing Molex pins, part number 39-00-0031 or equivalent. Power is to be supplied at either the 44 pin connector or the 12 pin connector, but not both. Interface Connector Pins Pin 41 +5V LOGIC Pin 43 GND Pin 42 +5V MOTOR Pin 44 GND Note Power should be separately supplied to the logic and motor power input pins to minimize cross coupling of noise to the drive electronics. Task File Interface Connector ----------------------------- A 44 pin Task File Interface connector is mounted on the printed circuit board. The recommended mating connector is AMP part number 1-487620-9 or equivalent. Two drives may be daisy chained together at this connector. The maximum cable length is two feet. Signal Levels ------------- All signal levels are TTL compatible. A logic 1 is > 2.0 Volts. A logic 0 is from 0.00 Volts to 0.70 Volts. Air Filtration System --------------------- The head-disk assembly is a sealed enclosure with an integral 0.3 micro filter which maintains a clean environment for the heads and disks. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle. The motor/ spindle assembly is dynamically balanced to provide a minimal mechanical runout to the disks and to reduce vibration to the HDA. A dynamic brake is used to provide a fast stop to the spindle motor when power is removed, or upon intitiation of STANDBY MODE. Installation of the Drive and AT Adapter Card --------------------------------------------- 1. Remove power to the computer 2. If another hard disk controller is installed, it is necessary to prevent it from responding to the addresses 1F0-7H and 3F6-7H. It is also necessary to ensure that the controller is electrically disconnected or tri-stated from IRQ14 of the mother- board bus. This may be done either by removing the board, by electrically disconnecting the signals from the interface, or by setting the jumpers of the board to select to disable the hard disk controller. 3. Insert the board into any available card slot. 4. Configure the Host adapter for the correct configuration of your computer BIOS. Adapter Card Jumpers E1 and E3 always not installed E2 and E4 always installed Note: E3 and E4 are located in a straight line with a pin between them, as shown below. Jumper in refers to the pin jumpered to the center pin. E3 E4 o o o 5. Connect power to the drive. 6. Run the DOS FDISK program to establish DOS partitions. Note: DOS 3.2 and below have limitations of 32 megabytes unless software utility is used to overcome this. 7. Run the DOS format program by typing "Format C:/S". The volume may be named with the addition of the "/V". The format will be completed and the system transferred if the "/S" option was used. If the "/V" option is used, the system will ask for a volume name. 8. Files can then be copied to the C: drive from the floppy. 9. When the system is rebooted, the system should boot from the hard drive (Drive C:) if the A: floppy drive is empty. Changing Between XT and AT -------------------------- Conner AT/XT drives are capable of running on either AT or XT without any modifications. There is an interface pin provided to determine what interface (AT or XT) is to be active. To change between the two, change the level of the interface pin 44 and then issue either a software or a hardware reset or cycle power to the drive. If this method is used, it is possible on most versions of DOS to take a drive that has the DOS System on it and transfer it between an AT and XT machine. XT Evaluation Adapter Board --------------------------- Conner Peripherals has designed an adapter board for use in XT systems to aid in avaluation of the drive. The drive requires a 2764 or equivalent disk BIOS or option ROM that is IBM compatible. Jumper E1, when jumpered, enables the ROM. The boards act as a pass-through to the embedded controller on the drive. If the ROM location is not used, code that directly talks to the drive must be written. Neither the ROM nor any drive code is currently supplied by Conner Peripherals. The drive will support DMA and responds to addresses 320h-323h. The drive will respond properly to commands issued by the Host to this address that are compatible with the IBM disk drive command set. There are additional commands that the Conner drive will support. Installation of the Drive and XT Adapter Card --------------------------------------------- 1. Remove power to the computer 2. If another hard disk controller is installed, it is necessary to prevent it from responding to the addresses 320-323. 3. Insert the board into any available card slot. 4. Configure the Host adapter for the correct configuration of your computer BIOS. Jumper E1 is installed if board BIOS location is to be used. 5. Connect power to the drive. 6. Run the DOS FDISK program (or equivqlent) to establish DOS partitions. 7. Run the DOS format program by typing "Format C:/S". The volume may be named with the addition of the "/V". The format will be completed and the system transferred if the "/S" option was used. If the "/V" option is used, the system will ask for a volume name. 8. Files can then be copied to the C: drive from the floppy. 9. When the system is rebooted, the system should boot from the hard drive (Drive C:) if the A: floppy is empty. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CP4044 PRODUCT MANUAL REVISION 1.7 AUGUST 1990 Key Features ------------ The CP4044 is a high performance 3.5 inch low-profile (0.78") 42.6 megabyte (formatted) disk drive with 29 ms seek time and is designed to operate on IBM PC/AT or PC/XT (or equivalent) in translate mode. The drive features low power requirements and high shock resistance, enabling battery operation in portable environments. Because the drive contains the AT Task File and XT Register Set within its control logic, it requires a simplified adapter board to operate. Conner Peripherals has developed an adapter board to be used in conjunction with the drive on an AT or equivalent system. It also requires a simplified XT adapter board. - Low power requirements, enabling battery operation in portable environments - .78" high - 5 Volt Only Power Requirement - High performance rotary voice coil actuator with embedded servo system - Two of seven run length limited code - High shock resistance - Sealed HDA - Automatic actuator latch against inner stop upon power down. - Microprocessor-controlled diagnostics routines that are auto- matically executed at start-up - Automatic error correction and retries - Block size 512 bytes - Emulates Task File and supports additional commands - Supports all XT and Additional Commands - Up to two drives may be daisy-chained on the AT interface and one drive on the XT - Translate mode (17 sectors, 5 heads, 980 cylinders) is supported Seek Times ---------- +----------------------------------+--------+ | track to track max. | 8 ms | +----------------------------------+--------+ | Average msec. max. | 29 | | Average msec. max. | 50 | +----------------------------------+--------+ |Latency msec. avg. | 10.3 | +----------------------------------+--------+ The average seek time is determined by averaging the seek time for a minimum of 1000 seeks of random length over the surface of the disk. Functional Description ---------------------- The CP4044 contains all necessary mechanical and electronic parts to interpret control signals, position the recording heads over the desired track, read and write data, and provide a contaminant free environment for the heads and disks. Read/Write and Control Electronics ---------------------------------- One integrated circuit is mounted within the sealed enclosure in close proximity to the read/write heads. Its function is to provide head selections, read preamplification, and write drive circuitry. The read/write heads are supported by a mechanism coupled to the voice coil actuator. The single microprocessor controlled circuit card provides the remaining electronic functions which include: - Read/Write Circuitry - Rotary Actuator Control - Interface Control - Spin Speed Control - Dynamic Braking - Power Management The microprocessor performs diagnostics upon application of power. If an error is detected the drive will not come READY. At power down or the start of STANDBY MODE the heads are auto- matically retracted to the inner diameter of the disk and are latched and parked on a landing zone that is inside the data tracks. Read/Write Heads and Disks -------------------------- Data is recorded on one 65mm diameter disk through two miniature Metal-in-Gap (MIG) heads. Error Correction ---------------- The disk performs internal error correction. The error correction polynominal is capable of correcting one error burst with a maximum of 8 bits per 512 byte block. Split ECC --------- The new generation of Conner driver feature a split sector with separate ECC's for each half of the sector's data field. This allows improved error correction performance. The first 245 bytes of the sector are written with their own ECC which allows for a correction of any single defect of up to 8 consecutive bits. The second 267 bytes of a sector also have their own ECC. This allows for one ECC correction for each half of a sector, or up to two correction for per sector depending on placement of the defects. IBM diagnostics expect an uncorrectable error to be reported when there are two defects more than 8 bits apart. This will not happen if the defects are in different segments of the sector. In that case the improved correction capability will correct bot errors. Also, for most systems IBM only transfers 4 bytes of the syndrome on a Read Long. The CP4044 will return 512 bytes of data plus 7 bytes of ECC syndrome from the second segment in XT mode and in the AT mode. Error Codes ----------- The following table list the error codes and types related to byte 0 of the Sense Block after the Request Sense command. Type 0 (Drive) Error Codes 0 No error 1 No Index Signal 2 No Seek Complete 3 Write Fault Detect 4 Drive not Ready 6 No Track 0 after Recalibrate 8 Seek in progress reported after Test Drive Ready Type 1 (Controller) Error Codes 0 ECC error in the ID field 1 Uncorrectable data error during a read 2 Address Mark not found 4 Sector not found 5 Seek error.

Evaluation Adapter Board ------------------------ In order to facilitate evaluation and aid those manufacturers interested in quickly getting the disk drive running, Conner Peripherals has developed an adapter board to be used in conjunction with the drive on an AT or equivalent system. The drive requires no special driver program as it works with the existing AT Bios or equivalent. It is hoped that the interface will be incorporated into the motherboard of the AT device or on some other multi-function adapter. The artwork and Bill of Materials are available upon re- quest. Acoustic Noise -------------- The sound pressure level will not exceed 40 dBA at a distance of 1 meter from the drive.
