NOTATIONAL CONVENTIONS The following conventions are used throughout this manual: BT-542 the term used to refer inclusively to the BT-542B, BT-542S, and BT-542D boards. INSTALLATION GUIDE This section describes how to unpack, to inspect, to configure, and to install the BusTek BT-542B, BT-542S, and BT-542D host adapter boards in a PC/AT host system. It also describes how to initialize the software for operation in DOS systems. The BT-542B supports single-ended SCSI drives with asynchronous and synchronous data rates of up to 5 MBytes/sec. The BT-542S supports single- ended SCSI drives with asynchronous data rates of up to 7 MBytes/sec and synchronous data rates of up to 10 MBytes/sec with the proper termination and cabling. The BT-542D supports differential SCSI drives with asynchronous data rates of up to 7 MBytes/sec and synchronous data rates of up to 10 MBytes/sec. Throughout this manual the term "BT-542" refers collectively to the BT-542B, BT-542S, and BT-542D. Unpacking and Inspection Before handling the BT-542 make sure your body is grounded with a grounding strap. Touch your computer on a metal part to discharge static electricity before handling the board. The board should always be held by the edges after static electricity is discharged. While practicing appropriate anti-static precautions remove the BT-542 from its protective envelope. Check that your shipment is complete according to the accompanying shipping list. Then verify that no physical damage occurred during shipping by inspecting the board for bent pins, loose parts, broken traces, and chipped or broken connectors. Installation Tools The following items, available from any authorized dealer, may be needed to assist with the installation of the BT-542 for your system: o PC/AT technical manuals o Hard disk drive(s) manuals o Floppy disk drive(s) manuals o PC/AT DOS diskette(s) o SETUP, FDISK, and FORMAT programs o Small screwdriver o Small needle-nosed pliers. Configuration Instructions General The BT-542 must be configured for use by performing the following actions: o Setting on-board switches and jumpers o Configuring SCSI devices o Verifying that the terminators are installed correctly o Placing the BT-542 into the AT slot and o Cabling the on-board connector to a SCSI target. BT-542 Switch and Jumper Settings The BT-542 operates with most AT class PCs with the factory set jumpers and switches in the two switch bays. The BT-542's switch bay settings and jumpers will need to be changed if conflicting port assignments or memory allocation is encountered. The locations of these switches and jumpers for the BT-542B are shown in Figure 1. Figure 2 shows the locations of these switches and jumpers for the BT-542S and the BT-542D. The default settings for switches and jumpers for the BT-542B, BT-542S, and BT-542D as shipped from the factory are listed in Tables 1-5. For switch and jumper information that is specific to the BT-542B, refer to the heading "BT-542B Specific Switch and Jumper Settings" later in this manual. For switch and jumper information that is specific to the BT-542S and BT-542D, refer to the heading "BT-542S/BT-542D Specific Switch and Jumper Settings" later in this manual. For a summary of the BT-542 switch and jumper information, refer to Table 10 and 11. Before installing the BT-542, verify that the switch settings and jumpers have been set according to the target system's operating requirements. WARNING Change the switches and jumpers before installing the BT-542 board into the AT compatible computer. Make sure that you are properly grounded before doing so. Host Adapter SCSI ID (BT-542). Switch Bay 1's Switches 1, 2 and 3 set the BT-542 SCSI Address (in binary). The default SCSI ID is 7. Complete settings of Switches 1, 2 and 3, and the resulting SCSI ID are shown in Table 1. The BT-542's BIOS requires that your SCSI drives be configured for SCSI ID 0 or 1. This requirement is important only if you intend to boot your system from the BT-542. SCSI Parity (BT-542). Switch Bay 1's Switch 4 sets the SCSI bus parity check. The default setting is on, parity enabled. Setting Switch 4 to off disables the SCSI bus parity. Enable > 1 GB Support (Revision 'G' and above of the BT-542). To support this >1 GB feature, Switch Bay 1's Switch 5 has been re-defined. For revision 'F' and below, Switch Bay 1's Switch 5 is used to enable/disable "SCSI Auto Sense." (The default ON setting enables the SCSI Auto Sense function for revision 'F' and below.) For revision 'G' and above, this switch is used to enable/disable > 1 GB support. For Revision 'G' and above by default the >1 GB support option is disabled. To enable this option, you must set the BT-542's Switch Bay 1's Switch 5 to "0" (OFF). After you have enabled this > 1 GB feature, the host adapter can support up to seven SCSI disk drives with each drive up to 8 GB in capacity. Example of the >1 GB Support - If a disk drive is more than 1GB but less than 2 GB in capacity, you should set the host adapter for >1 GB support. If you were to run FDISK, it will display half of the cylinder count of the total drive capacity because now the disk is formatted as 2 MB per cylinder. <1 GB >1 GB >2 GB >4 GB Sectors Per Track 32 32 32 63 Number of Heads H=64 128 256 256 Capacity Per C=1 MB 2 MB 4 MB 8 MB Cylinder SCO UNIX Limitations - Disk capacity cannot exceed 1 GB due to the SCSI device driver that is built into SCO UNIX. Novell Limitations - Novell NetWare will support greater than 1 GB on the disk drive if the BIOS on the host adapter is disabled, and you are booting from another device. This enables NetWare to use the entire disk drive as a NetWare volume. If the BIOS is enabled and you are booting from a DOS partition, then there is a 1 GB limit. This limitation is due to the fixed parameters in the NetWare SCSI device driver. SCSI Synchronous Negotiation (BT-542). The default setting of Switch Bay 1's Switch 6 is the on position which disables synchronous negotiation initiation by the BT-542. This mode assumes that a SCSI target device connected to the BT-542 will initiate the synchronous negotiation. Some target devices require that they initiate the synchronous transfer sequence. Such devices may fail to respond to commands from the BT-542 if a synchronous negotiation occurs unexpectedly. Conversely, other target devices may expect an initiator to begin the synchronous negotiation sequence. If this class of SCSI target devices is connected to the BT-542, Switch 6 may be set to the off position to allow the BT-542 to initiate the negotiation for a synchronous data transfer with a selected SCSI target device. Host AT DMA Channel (BT-542). Switch Bay 1's Switches 7 and 8 default on settings select the DMA Channel 5 for data transfer to the PC/AT host. The DMA channel which is reported to the PC/AT host at the Inquire Configuration command is set by these switches. Complete settings of Switches 7 and 8 are shown in Table 2. Switch Bay 2 Switch Bay 1 __________ __________ off| ........ | | ........ | off on | ........ | | ........ | on | 12345678 | | 12345678 | |__________| |__________| ________ ____________________ _______ | Switch | DMA STATUS | | 0=ON | | Bay 1 | | | 1=OFF | | 7 8 | | |_______| |________|____________________| | 0 0 | Channel Disabled | | 1 0 | Channel 7 | | 0 1 | Channel 6 | | 1 1 | Channel 5, default | |________|____________________| Table 2. BT-542 Host DMA Channel I/O Port Base Address (BT-542). Switch Bay 2's Switches 1, 2, and 3 select the starting address of the block of four I/O ports required by the BT-542. The default starting address is 330H. Optional settings of the starting- address switches, 1-3, and their corresponding Hex starting addresses are shown in Table 3. _____________________________ ______ | Switch | I/O ADDRESS | | 0=ON | | Bay 2 | | | 1=OFF| | 1 2 3 | FUNCTION | |______| |---------|-------------------| | 0 0 0 | Reserved | | 1 0 0 | 134h-137h | | 0 1 0 | 234h-237h | | 1 1 0 | 334h-337h | | 0 0 1 | Reserved | | 1 0 1 | 130h-133h | | 0 1 1 | 230h-233h | | 1 1 1 | 330h-333h,Default | |_________|___________________| Table 3. BT-542 I/O Port Addresses Host AT Interrupt Channel (BT-542). Default Switch Bay 2's Switches 6-8 select the host AT interrupt Channel 11. Complete settings of Switches 6 through 8 are given in Table 4. In addition to setting the switch bay for the correct interrupt, make sure that you also set Jumpers W3-W8, as described as follows. _____________________ ______________________ _______ | Switch | CHANNEL | | Jumper | HOST | | 0=ON | | Bay 2 | | | | INTERRUPT | | 1=OFF | | 6 7 8 | | | | CHANNEL | |_______| |---------------------| |-------------------- | | 0 0 0 | Reserved | | W3 | 15 | | 1 0 0 | Reserved | | W4 | 14 | | 0 1 0 | 15 | | W5 | 12 | | 1 1 0 | 14 | | W6 | 11, Defualt | | 0 0 1 | 12 | | W7 | 10 | | 1 0 1 | 9 | | W8 | 9 | | 0 1 1 | 10 | |______________________| | 1 1 1 | 11,Default | |________|____________| Table 5. BT-542 Host Interrupt Channels Table 4. BT-542 Host Interrupt Channel Host Interrupt Channel (BT-542). Jumpers W3-W8 set the Host Interrupt Channel. To configure the Host Interrupt Channel properly ensure that the corresponding switches in Switch Bay 2 (6,7,8) match the jumper settings shown in Table 5. Only one jumper must be shorted (installed) for proper operation. Host I/O Channel Ready Enabled (BT-542). Jumper W17 controls the Host I/O Channel Ready function. The default setting for the jumper is "A-B" which enables the I/O Channel Ready signal; thereby, allowing the BT-542 to respond to I/O devices (memory or I/O) that require a data transfer cycle to be lengthened. The BT-542 will wait until the I/O Channel Ready signal is returned to the Ready (high) state. Setting "B-C" disables the I/O Channel Ready signal. When the I/O Channel Ready signal is disabled, it prohibits the BT-542 from responding to the I/O Channel Ready signal. This may be necessary if another I/O device does not properly manipulate the I/O Channel Ready signal. Floppy PRIMARY/SECONDARY I/O Address (BT-542). The default setting for Jumper W14 (open) produces a primary floppy disk address of 3FX. The secondary address of 37X is set when the jumper is shorted. Floppy Disk Controller Enable (BT-542). Default jumper settings of W15 and W16 closed allows the floppy disk controller to respond to host Read and Write commands. When both Jumpers W15 and W16 are open, the floppy disk controller will disregard any Read or Write signal. Not Used or Reserved Jumpers. Reserved Jumpers W2 and W9, which select PROM sizes, are set at the factory. BT-542B Specific Switch and Jumper Settings This section describes the switch and jumper settings that are specific to the BT-542B. ROM BIOS Base Address (BT-542B only). Switch Bay 2's Switches 4 and 5 select the block of address space reserved for the starting address of the BT-542B's BIOS. Complete settings of Switches 4 and 5, including the default setting (0DC000H), are shown in Table 6. If more than one host adapter is installed in the same system, only one may have the BIOS enabled. The BIOS on each additional host adapter must be disabled. Rather than using Switch Bay 2's Switches 4 and 5 to define the BIOS base address, the BT-542S and BT-542D use Switch Bay 3's Switches 3,4, and 5. For more details, refer to Table 9 under the next heading, "BT-542S and BT-542D Specific Switch and Jumper Settings".

BT-542 Bios Base Address DMA Transfer Speed (BT-542B only). Jumper settings for W11 and W13 determine the DMA transfer speed after a hard reset or power on. A Set Bus Transfer Rate host software command may be issued to the BT-542B to override these jumpers until the next hard reset or power on. The default setting is W11 and W13 removed (open). Table 7 shows the DMA transfer rate settings. The BT-542S and the BT-542D do not have W11 and W13. Instead Switches 1 and 2 of Switch Bay 3 are used to specify the DMA transfer speed. _____________________________ | JUMPER | HOST BUS TRANSFER | | W11 W13 | RATE | ______ |---------|-------------------| | 0=ON | | 0 0 | 5.0 MB/sec | | 1=OFF| | 0 1 | 5.7 MB/sec | |______| | 1 0 | 6.7 MB/sec | | 1 1 | 8.0 MB/sec | |_________|___________________| Table 7.

Install the BT-542 in your PC/AT host system by performing the following steps. 1. Remove power from the PC/AT host system. 2. Referring to the PC/AT host system owner's manual, open the case to gain access to the motherboard and expansion slots. If the comput-er has been on, wait a few minutes until the power supply case has cooled down inside the computer. If the power supply case is cold, touch it to discharge any static electricity that may be on your clothes or body. If a disk controller drive board has been installed, remove all connecting cables to the board and then lift it out of the PC/AT host system. 3. Remove the mounting screw and the existing bracket from the rear panel behind the 16-bit slot that has been selected for insertion of the BT-542. The slot closest to the disk drives is the best choice. 4. If the BT-542B will be installed in a PC/AT host system which is not at either end of the SCSI bus, terminators RP5, RP6, and RP7 on the board will need to be removed. RP5, RP6, and RP7 are 220 ohm/330 ohm resistor packs. For the BT-542D, terminators are RP11 through RP18. RP11, RP12, RP15, and RP18 are 150 ohm resistor packs. RP13, RP14, RP16, and RP17 are 330 ohm resistor packs. For the BT-542S, terminators are RP8 and RP9. RP8 and RP9 are 110 ohm resistor packs. See the following heading, "Host Adapter Integration," for more information regarding device termination. The BT-542 is shipped with terminators installed. 5. Press the BT-542 downward into the 16-bit selected slot, align the mounting bracket, and reinstall the mounting screw. CAUTION Make sure that the board is properly seated in the slot. 6. Connect the large 50-pin connector within the PC/AT host system to the single-ended SCSI connector, J3. Place the connector cable around the power supply and over any other boards. Depending on the configuration of your computer, other types of cables could be used. See the heading, "Cabling Requirements," in this manual for details. 7. If the floppy controller on the BT-542 will be used, connect the smaller 34-pin connector from the floppy disk drive to the J2 connector marked "Floppy." Make sure the ribbon cable is installed correctly. The dark stripe on the cable indicates where Pin #1 is connected. 8. Insert the four-pin header connector from the drive activity LED on the front panel of the PC/AT to connector J1 on the BT-542. This connector is reversible and may be plugged into J1 in either direction. 9. Verify that all connections are secure. 10. Reattach and close the cover of the PC/AT host system as described in the system owner's manual. Host Adapter Integration Device Termination SCSI devices are daisy chained together with a common cable. All SCSI devices operate on common signals and both ends of the cable are terminated with hardware terminators. Terminators, which can be connected to either SCSI devices or SCSI cables, are required to make data transfers on the SCSI bus reliable. Devices connected to SCSI chains must have the correct number of terminators for proper operation and to prevent damage to the SCSI chip on the BT-542. There can be no more than two terminators in a chain of SCSI devices-one at each end of the physical chain. Thus if more than two SCSI devices are connected in a SCSI daisy chain, the middle device(s) in the control cable must have the terminator resistor packs on the device(s) removed. See Figure 3 for possible configurations of ter-minators in a SCSI system. Cabling Requirements Selecting the proper SCSI cable for a particular system configuration is of great importance. If two or more SCSI devices are configured in a SCSI daisy chain, the devices must be connected by a 50-conductor, daisy-chain cable. Before plugging in cable connectors, check that the "t" mark molded on the connector or the colored stripe on the cable (indicating the location of Pin 1) matches Pin 1 of the connector on the BT-542. SCSI Device ID Selection The SCSI ID is a number between 0 and 7 assigned to any SCSI device. The SCSI ID number is used by the computer to communicate with the devices connected to it. All SCSI devices must have a unique SCSI number to identify it on the SCSI chain. When two or more SCSI devices communicate, a SCSI device is usually fixed as either an initiator or a target; however, some devices are capable of performing either role. Devices with higher ID numbers have a higher priority in communicating with the computer. Most SCSI peripheral devices are shipped with a preassigned SCSI ID number. A SCSI ID switch is usually located on the back panel of such devices. Change the SCSI ID of other peripheral devices only as recommended in the owner's manual. Refer to the heading, "BT-542 Switch and Jumper Settings," in this manual for information on how to set the SCSI ID number of the BT-542. Hard Disk Initialization This section describes the system set up, initialization, partitioning and formatting of hard disk drives used with the BT-542. These procedures will erase all data on your disk drives. Before following these procedures make sure that all necessary data is backed up on another drive. Set-up, Initialization, and Partitioning Procedure To perform set up, initialization, and partitioning, proceed as follows. 1. After plugging in and connecting your BT-542 (see the previous parts of this section), apply power to the PC/AT host system. 2. Insert the system diagnostic diskette in the drive, or execute the host's internal diagnostic/set-up program. See your particular sys-tem's installation instructions. 3. In accordance with the menu that appears on the system monitor, run SETUP and configure the host CMOS RAM options. Set the hard disk option for SCSI drive to "No Hard Drive Installed." The following Steps 4 through 8 may not be necessary if your SCSI hard disk drive has already been formatted. 4. Reboot the PC/AT host system and insert the DOS diskette containing the DEBUG program. 5. After the DOS prompt, type the following for low-level format: 6. Perform the following steps on your screen monitor to configure and perform a low-level format on attached devices: A) The "SCSI Fixed Disk Format Utility" appears on the screen. Enter "1" to view the attached devices, then press the return key. B) A list of all attached drives appears under the option prompt. Press the "2" key until the drive to be formatted is the current drive. C) Press "3" and then press the return key to format the drive. The following prompt appears. All data on this drive will be lost! Proceed with low level formatting? (Y/N) __ Enter "Y" to proceed with low-level formatting and follow the instructions as they appear on the screen. D) The system will format the SCSI drive selected. When the format is completed, press any key to return to the main menu shown in the preceding Step 6A. Enter "4" to verify the drive and then press the return key. The following prompt appears. All data on this drive will be verified. and bad data areas will be reassigned.

Warranty Information If damage to the board has occurred, return it in the protective envelope with this manual to your BusTek board supplier. The shipping agent should also be notified if the unit has been damaged during shipment. The BusTek warranty conditions are given in the back of this manual. APPENDIX A--BT-542 INTERNAL DIAGNOSTICS When power is first applied to the BT-542, an on-board diagnostic routine is run to verify that the major functional components of the board are operating correctly. The 80C20 bus master chip, the SCSI controller chip, the firmware PROM, the local RAM and internal data buses are tested. Results of the tests are indicated by an LED on the board. The LED will first turn on when power is applied. If the diagnos-tics find no malfunctions, the LED will then go off. In normal oper-ation, the LED will be illuminated when command or SCSI bus activity occurs on the board. If an error is detected by the diagnostics, the LED will repeatedly flash a specific number of times, with a long pause between flashes, to indicate the board function which failed. This will continue un-til the board is powered down or reset. Failure interpretation from the number of flashes is as follows: Number of LED Flashes Interpretation of Failure Always On BT-542 is not operating or terminators are missing. 1 Firmware ROM checksum failure. 2 Local RAM test failure. 3 SCSI controller chip or SCSI interface failure. 4 Internal data bus failure. 5 Internal address bus failure. 6 80C20 bus master chip failure 7 SCSI drive type mismatch* Constantly Flashing Fuse Blown. *This error message is only applicable to the BT-542D when single-ended SCSI drives are connected to the differential SCSI bus.
