1. INTRODUCTION The DC-395 series is a SCSI (Small Computer System Interface) bus to PCI bus host adapter, which complies to the PCI 2.1 specification with Plug-&-Play (PnP) readiness. By using the Disconnect/Reconnect technique, performance degradation during multitasking operations is prevented. Other enhanced SCSI-2 features such as scatter-gather and command-tag queuing are supported.
2. HARDWARE SETUP Static Precautions Static electricity can be a serious danger to the electronic components on this board. To avoid damage caused by electrostatic discharge, observe the following precautions: ü Don’t remove the board from its anti-static packaging until you are ready to install it into a computer case. Also, handle add-in cards and modules by the edges or mounting bracket.
2. HARDWARE SETUP 2.
2. HARDWARE SETUP 2.2 Setting the Jumpers DC-395U/395UW/F: JP1 (LED) SCSI Device Activity LED Indicator (JP1) JP1 is used to indicate activity of the SCSI devices controlled by the DC-395 series adapter, and should be connected to the cable leading to the Hard Drive LED on the front panel of your computer case. 2.3 Setting the SCSI IDs Each SCSI device attached to the SCSI card, as well as the card itself, must be assigned a unique SCSI ID number.
2. HARDWARE SETUP 2.4 Checking the Terminators on the SCSI Bus In order to stabilize the SCSI bus, only two sets of terminators can be installed - one at each end of the SCSI bus. The DC-395 series is equipped with Active Terminators that automatically switch from Enabled to Disabled or vice versa by scanning the devices connected on the SCSI bus. So, manual termination adjustment is not required. The following explains the terminator configuration of other devices on the SCSI bus: 1.
2. HARDWARE SETUP 2.5 Cable Connection Model # External Internal DC-395U CN1: 50-pin; 8-bit CN2: 50-pin; 8-bit DC-395UW* CN1: 50-pin; 8-bit CN2: 68-pin; 16-bit (wide) CN3: 50-pin; 8-bit DC-395F CN1: 68-pin; 16-bit CN2: 68-pin; 16-bit (wide) CN3: 50-pin; 8-bit * Only two of the three connectors can be used to connect SCSI devices at the same time. External SCSI connector: This high density D-type SCSI connector is for connecting external SCSI devices.
3. CONFIGURING YOUR SCSI CARD 3.1 Setting the System BIOS After the DC-395 is inserted in an available PCI-BUS slot and the jumpers and cables are properly set, first turn on the power to your external SCSI devices and then power on the system. When installing a SCSI drive as drive C: (or D:), set the CMOS HDD drive type according to the IDE drive installed. The CMOS HDD is NOT related to SCSI HDD.
3. CONFIGURING YOUR SCSI CARD 3.2 Running the PCU (PCI Configuration Utility) Since the DC-395 series is PCI compliant with Plug-&-Play (PnP) readiness, the system should allocate the proper Interrupt Level, Adapter BIOS Address and other settings automatically. Still, entering the PCU allows you to view more information and set additional options for both the DC-395 series adapter and the SCSI Devices. Utilities for verifying bad blocks and low level formatting are also included.
3. CONFIGURING YOUR SCSI CARD 3.2.1 Show Adapter Information This screen displays detailed information about the SCSI chip, ROM BIOS address, I/O port address, IRQ, PCI interrupt line, etc. The information about the SCSI Chip, IRQ Trigger Type and Data Xfer Type is provided by the DC-395 series adapter itself. The rest of the information in this table is provided by the mainboard's BIOS, which should support the PCI PnP specification. This information cannot be modified.
3. CONFIGURING YOUR SCSI CARD 3.2.2 Set Adapter Options Set Adapter Options Adapter SCSI ID ………………………. Boot Device ID ………………………… Boot Device LUN ……………………... Boot From CD-ROM ………………….. INT13 Extension ……………………… Greater Than 1G Support ……………... More Than 2 Drives Support ………… Removable Media as BIOS Device …. Immediate Return on SEEK Command… Scan All LUN For Devices…………… Active Negation ……………………….. Power on RESET SCSI Bus …………..
3. CONFIGURING YOUR SCSI CARD • Booting from a removable SCSI device: The above applies. Also, the setting Removable media as BIOS device (see page 17) should be set to “Boot drive only” * • Booting from a SCSI CDROM: The setting Boot From CD-ROM (see below) must be “Enabled” (for CD-Changer, Boot Device LUN may need additional configuration). This setting takes precedence over the boot device setting in the mainboard’s BIOS.
3. CONFIGURING YOUR SCSI CARD the Greater Than 1GB Support feature only needs to be enabled if FAT is to be used as the file system. *NTFS and HPFS do not impose a 1024 cylinder limit. • NetWare and UNIX are two Operating Systems that do not have a 1024 cylinder barrier and therefore do not require that Greater Than 1GB Support be enabled.
3. CONFIGURING YOUR SCSI CARD * IDE HDD 1 none None Drive D: SCSI Device 0 Drive C: Drive D: (*) SCSI Device 1 Drive D: (*) (*) Number of drives supported by CMOS (2) has been reached. Device driver must be used for this device. Case 0: Case 1: Case 2: No IDE drives. Two SCSI drives can be controlled with BIOS INT 13H. One IDE drive is installed as drive C:. One SCSI drive can be controlled through BIOS INT 13H. Two IDE drives are installed as C: and D:.
3. CONFIGURING YOUR SCSI CARD Immediate return on SEEK command: Disabled(default)/Enabled. Enable this option to bypass the BIOS SEEK command. Scan all LUN for devices: Disabled(default)/Enabled. Each SCSI ID can have up to eight Logic Unit Numbers (LUN: 0-7). With this option enabled, all the LUNs for all SCSI IDs on the SCSI bus will be scanned and recognized as BIOS Devices. If Disabled, only LUN0 of each SCSI ID will be scanned and recognized as a BIOS device. Active Negation: Enabled(default)/Disabled.
3. CONFIGURING YOUR SCSI CARD 3.2.3 Set Devices Options This sub-menu allows you to change options for each device on the SCSI bus. Device information related to each SCSI ID is displayed in the lower portion of the screen. DC-395U/395UW/395F: MaxSyncXferRate replaced with MaxSyncXfers.
3. CONFIGURING YOUR SCSI CARD Note: Enabling this feature would reduce the load on your computer's power supply by allowing the DC-395 to turn on SCSI devices one at a time during system initialization, starting from the lowest SCSI ID. However, each device would be required to support this option. Tagged Command Queuing: Yes/No (default). The Yes option is useful for enhancing overall system performance under multi-tasking operating systems such as OS/2, Windows NT and Unix. Wide Negotiation: Yes/No.
3. CONFIGURING YOUR SCSI CARD 3.2.4 Show SCSI Devices This sub-menu provides general information for all devices on the SCSI bus: Select A Device For Display Device Information ID-LUN 0-0 ID-LUN 1-0 ID-LUN 4-0 SEAGATE ST32171N FUJITSU M2513A IMPRIMIS94241-7 0280 1000 1275 You can see more detailed information by selecting the desired drive: SCSI Device Information Vender ID ………………………………… Product ID ………………………….….….

3. CONFIGURING YOUR SCSI CARD 3.2.5 Low Level Format Utility Since most SCSI drives are already pre-formatted when shipped from their manufacturers, you can skip this section except in the following situations: • A disk drive is damaged • The disk drive has not been formatted with the 512B/block parameter After selecting the desired device and confirming the operation, the low-level format will proceed. Under normal circumstances, it is both unnecessary and inadvisable to perform lowlevel formatting.
4. DOS ASPI DRIVERS & UTILITIES This chapter describes in detail the various ASPI Drivers and Utility programs that are provided with the DC-395 Host Adapter Kit for use under the DOS operating system. To get up and running quickly under DOS, see Section 4.1 - Easy DOS Driver Installation Software for easy installation instructions. The major ASPI Drivers and Utilities are: • T3X5ASPI.
4. DOS ASPI DRIVERS & UTILITIES 4.1 Easy DOS Driver Installation Software (INSTALL.EXE) The DOS driver diskette provides an INSTALL.EXE file in the \DOS directory to provide easy driver installation for your SCSI devices. Under DOS, the driver installation will be necessary if either: a) More than two Hard Drives are installed and "More Than 2 Drives Support" is disabled (sec.3.2.2), or b) A SCSI device other than a Hard Drive is installed (CD-ROM, etc.
4. DOS ASPI DRIVERS & UTILITIES 4. The following screen provides information on the number of SCSI devices installed and asks if you want to install the drivers: Note: Only install the ASPI Hard Disk Driver if you have a removable device, such as an M.O. drive, or if More than 2 drives support is Disabled.
4. DOS ASPI DRIVERS & UTILITIES Please Key in the PathName where MSCDEX.EXE Resides C:\DC3x5 ENTER ---- Accept the Pathname ESC ---- Abort Install MSCDEX.EXE 7. You would then assign the first drive letter to be reserved for the CD-ROM drive(s). In this case, Drive: F is reserved for the first CD-ROM drive: 8. After confirmation, the installation program will modify both the CONFIG.SYS and AUTOEXEC.BAT files. This installation program will modify system CONFIG.
4. DOS ASPI DRIVERS & UTILITIES 4.2 Installing the ASPI Driver With the ASPI driver ASPI.SYS installed, you are able to run or install the following utilities and drivers: • TFDISK.EXE: Disk partitioning utility on the DC-3x5 series driver diskette • TRMDISK.SYS: Disk driver on the DC-3x5 series driver diskette • AFDISK.EXE: Disk partitioning utility from Adaptec • ASPIDISK.SYS: Disk driver from Adaptec • TRMCD.
4. DOS ASPI DRIVERS & UTILITIES Using the /d option, you have the ability to reserve up to 9 logical drives for each SCSI device. However, you must keep the total number of partitions (logical drives) reserved by the driver to within 16. This option is important for removable media devices. If you do not reserve enough logical drives for your removable media, some of the logical drives may go unrecognized. To install, add a line after ASPI driver in the CONFIG.SYS: • • • • • • DEVICE=C:\ASPI\ T3X5ASPI.
4. DOS ASPI DRIVERS & UTILITIES Note: With the More Than 2 Drives Support option enabled in the PCU, you will be able to install up to eight drives without installing device drivers. Of course, your DOS version must be 5.0 or higher. LOCK/UNLOCK functions are crucial for data integrity of removable devices and need to be supported by drivers. To prevent the data from being destroyed by improper operation of your devices, it is recommended to use the DOS 4.
4. DOS ASPI DRIVERS & UTILITIES Cylinders= XXX – Depends on drive’s capacity. • Using 255 heads, 63 sectors parameters: Heads = 255 Sectors = 63 Cylinders = XXX – Depends on drive’s capacity. After partitioning the disk, you must also choose "Create Logical Drive" to assign a DOS drive letter to the partition. Then, exit and re-boot the system. 4.5 Installing the CD-ROM Driver TRMCD.SYS is the driver for CD-ROM and CD-Changer devices. To enable a CD-ROM under DOS, you will also need MSCDEX.
4. DOS ASPI DRIVERS & UTILITIES 4.6 Installing Tape Streamer (DAT) After installing the ASPI.SYS driver, the DC-395 can support the following tape backup subsystems under DOS. • SYTOS PLUS Tape backup program from SYTRON CORP. • SYTOS V3.xTape backup program from SYTRON CORP. • ARCserve/SoloTape backup program from Cheyenne CORP. Note that the ASPI driver only provides the interface for tape systems. You must purchase the desired tape backup software program separately.
5. NETWARE DRIVERS The DC-395 supports drivers for NetWare V3.12/SFT-III/4.00/4.01/4.02/4.1x/4.2/4.2SB/5.0.

C. General Troubleshooting Tips Most controller errors are traceable to external factors, such as conflicts with other installed cards, bad or incorrectly configured drives, loose cables, improper SCSI termination, or other installation errors. To troubleshoot SCSI problems, try simplifying your hardware configuration by removing some devices from the system and then adding them back one at a time. For slow external SCSI devices you may also try to set the “Sync Negotiation” to “No”, i.e.
C. General Troubleshooting Tips 5. A connected device is not recognized by the DC-395: • If the device is a hard drive, particularly an older one, there may not be a sufficient delay time specified in the DC-395 PCU. You can tell if this is the case by simply warm booting the computer after the drive has had plenty of time to spin up. If the controller sees the drive then, go into the DC-395 BIOS and increase the setting: Delay Before BIOS Scans Device.
D. Flash BIOS Programming Utility Flash BIOS is featured on DC-395 series with the exception of DC-395 (The word “FLASH” on the adapter’s BIOS chip indicates flash support). Updating the DC-395U/UW/F BIOS Code is made easy with the TRMFLASH.EXE Utility, which can be found in the directory of the driver disk. Since the DC-395U/UW feature FLASH BIOS, it is not necessary to change the actual BIOS chip in order to upgrade the SCSI BIOS. The user can simply re-program the old BIOS using the TRMFLASH.
