- Radio Interference
- Statement
-
- This Western Digital product, the 1006V-MM2, has been verified to comply with
- the limits for a Class B computing device pursuant to Subpart J, Part 15 of FCC
- Rules when installed in a system which also complies with the above rules.
- These rules were established to provide reasonable protection against radio and
- TV interference in a residential installation, but there is no guarantee that
- interference will not occur in any given situation.
-
- If interference is suspected, consult your computer system's User's Guide for
- radio interference information. Usually eliminating the interference involves
- reorienting the antenna, moving the computer away from the radio or TV, or
- plugging the computer into a different outlet than the radio or TV.

- Introduction
- ********************************************************************
-
- Your new SpeedKit 1006V hard disk controller board offers the following:
-
- Supports up to two ST-506 compatible MFM hard disk drives (with up to 16
- heads and 2048 cylinders each).
-
- Supports up to two floppy disk drives (360k, 1.2Mb, 720k, 1.44Mb).
-
- One-to-one interleaving for the fastest possible data throughput.
-
- This controller board is designed for use with the IBM Personal Computer
- AT and compatibles, including most 80386-based computer systems.
-
- Your new controller is a direct replacement for your existing hard/floppy
- disk drive controller, so no system modifications are necessary. However,
- you'll need to back up all of your files from your hard disk drive(s)
- before installing the 1006V-MM2, since there's no guarantee that your old
- controller is compatible with the new one. To obtain one-to-one
- interleaving, a re-format of the hard disk drive(s) is required. Included
- in this package is Western Digital's WDFMT low-level formatting utility to
- facilitate this.
-
- The floppy controller of the 1006V-MM2 can be disabled, so if you have an
- existing floppy controller board or if it's built into the computer's
- motherboard, you'll need to disable the 1006V-MM2 floppy controller before
- installing it by placing a jumper on Pins 1-2 of W4. See Page 24 for
- details.
-
- The 1006V-MM2 requires DOS version 3.0 or higher (version 3.3 or 4.0
- recommended) or OS/2 version 1.1 or higher. It is also compatible with SCO
- Xenix and Novell Netware.

- About hard disk drives:
- ********************************************************************
-
- Most ST-506/412 hard disk drives can be used with the 1006V-MM2 board. However,
- the drive should closely match the drive type table built into your computer's
- system BIOS. The original IBM AT only had 15 drive types that it supported, but
- many compatible computers support up to 47 drive types. You'll need to refer to
- the documentation that came with your system to see which types of drives it
- can support. If you have two drives, they can be of different types. You don't
- need to be concerned about this if you are using the hard disk that came with
- your computer, but if you are adding another drive, or installing your first
- drive, you'll need to know some specific information about it such as the
- number of heads and cylinders. You don't have to know what all that means, just
- the numbers. Refer to the drive's Owner's Guide for more information.
-
- For example, suppose you have an IBM AT computer which came from the factory
- with a 20 megabyte hard disk. It would be a Type 2 drive, with 612 cylinders
- and 4 heads. You want to replace the original drive with a 40 megabyte Seagate
- ST-251 that has 820 cylinders and 6 heads. But the original AT does not have a
- drive type that matches the configuration of the new drive. Consulting the IBM
- AT User's Guide, you find that the closest match would be a Type 3 drive, which
- has 612 cylinders and 6 heads. In this case, using the IBM Setup program (or
- your compatible system's equivalent) you'd set the drive type accordingly.
-
- Now it gets tricky: Even though the new drive is a 40Mb unit, you can only
- access 32Mb of the drive, because the computer thinks that it has fewer
- cylinders than it really does so it can't "see" the extra capacity. In this
- situation you'll have to purchase a disk utility program to override the drive
- type table settings. Be aware of this limitation when purchasing your disk
- drive.
-
- On many compatibles, the above scenario wouldn't be true because most
- compatibles can support that drive and many others. All you need to do is look
- up the drive Type in your computer system's user's guide and match it to the
- configuration of the drive, then run Setup to tell the system about the new
- drive. Be sure to purchase only drives that match the available drive types
- that your computer can support.
-
- This is a limitation of the system BIOS of your computer, not of the
- controller.

-
- WARNING
- Back up your hard disk before doing anything else! Reformatting will
- destroy all existing information.
-
-
- Turn off your system and all attached peripherals, and remove the cover. You
- might need to refer to your user's guide for instructions on doing this. Locate
- the existing hard disk controller, and remove the screw at the rear. Carefully
- lift the controller out of the slot, just enough so you can remove the flat
-
-
-
-
-
-
-
-
-
-
-
- ribbon cables without interference from adjacent boards. Note which cable is
- connected to your floppy drive and set it aside. Now remove the controller from
- the computer and place it in an anti-static bag.
-
- CAUTION
-
- HANDLE THE CONTROLLER BOARD BY THE ENDS ONLY. SOME OF THE CHIPS ARE
- STATIC SENSITIVE AND DAMAGE MAY OCCUR IF THE BOARD IS HANDLED IMPROPERLY.
-
-
- Look at your new controller and note the locations of the connectors. Position
- J1 is for your floppy cable, connector J5 is for your wider hard disk cable
- (the control cable), J4 is for the data cable (the narrower one) of the first
- hard disk, and J3 is for the data cable of your second hard disk, if you have
- one. Connector J6 is for the LED wires which lead to the front of the case.
- Refer to Appendix A for more details about cables.
-
- First, attach the floppy cable to connector J1. The colored stripe on the edge
- of the cable corresponds to pin 1 of the connector, on the left edge. The cable
- should be keyed and will fit only one way. Attach the control (wide) and data
- (narrow) cables for your hard disk to connectors J5 and J4 (and J3, for a
- second hard disk).
-
- Lower the controller into the slot opening, and align the bottom edge with the
- slot connector. Gently press the controller into the slot. If you encounter
- resistance, check to make sure nothing is in the way. Secure the controller
- with the screw you removed from the old controller. Attach the LED wire to
- connector J6. Double-check your drive connections.
-
- Most drives have a few errors on them. These are usually written on a sticker
- on top of the drive, or on a slip of paper as a series of numbers in head,
- cylinder and byte offset format. All you need is the head and cylinder location
- of the defect. When you perform the format, you'll be asked to supply the media
- defects, so copy these numbers down now.
-
- If your old controller was a Western Digital AT-type controller (1002-WA2, 1003-
- WA2), and your hard disk has fewer than eight heads, your system will start up
- normally. If your drive has more than eight heads, place a jumper on W1, pins 7-
- 8 to maintain compatibility (see Page 24). The 1006V-MM2 controller is
- compatible with these older models, and you can still read and write data to
- the hard disk. However, there will not be any increase in performance until you
- re-format the hard disk using one-to-one interleave. If you had another brand
- of controller, or an XT (8-bit) type such as the Western Digital 1002-WX1, your
- system will report an error reading the hard disk (the drive activity light may
- be on for up to a minute), and you won't be able to access any data. If you
- just installed a new drive, the system will always report an error because it
- can't read information placed on the drive during low-level format.
-
- Now replace the system cover. Re-attach any cables you might have removed.
- Place your DOS diskette in the A: drive, and switch on your computer.

-
- NOTE
- If you previously had an XT-type controller in your computer, you'll need
- to run your computer's Setup program to tell your system about your hard
- disk because when using an XT-type controller in an AT-compatible system,
- you have to specify that no hard disks are attached, even when they really
- are.
