It provides a high-performance interconnection be- tween the Video Electronics Standards Association’s (VESA) bus and up Appendix A: BT-445C Switch Settings to seven Small Computer System Interface 6CSI) peripheral devices. The BT-440C/445C offers device driver support for major industry standard operating sys terns. BusLogic host adapters offer exceptionally high product reliability due to reduced component count and lower power ccnsumption. Minimized command overhead results in faster command execution. Adapter BIOS supports up to 8 GBytes capacity per disk. The BT-44OC is the same as the BT-445C, but without the floppy connector. For the remainder of this manual, BT-445C refers to both models except as noted. Hardware Requirements Your VESA computer needs: n One available expansion VL slot for each BT445C being installed n At least one 3.5” floppy drive nDC power for an internal 3.5” SCSI drive or an external subsystem You’ll need the following cables: w A 50-pin cable with a high density connector to connect the BT-445C to external devices m l-l introduction Hard Drive Setup connector Floppy connector BusLogic provides a low-level format utility as part of onboard adapter Internal SCSI connector configuration (see the AutoSCSI m description in Section 3). You can use this utility if your hard drive has not been previously formatted or requires a low-level format as indicated by error conditions. In addition, you need partitioning and high-level formatting tools which are used to prepare the hard drive for operating system installation. Your operating system software may incorporate these high-level format and partitioning functions as part of its operating system installation or may of- fer them as separate utilities. For example, DOS provides FORMAT and FDISK in its utilities suite. Supported Operating Systems (SCSI 2) BusLogic has embedded driver support in the kernel of the following op- era ting systems: l-1. Host Adapter n NetWare n UNIXWare H A 50-pin, flat ribbon cable to connect internal SCSI devices to the adapter n Windows NT w Solaris (for x86) H A 34-pin flat ribbon cable to connect a floppy drive (BT45C only) n Interactive UNIX n Vines n An optional four-pm cable to connect the drive activity LED on the host a SCOUNIX front panel to the adapter The BT-445C offers device drivers for the following operating systems: The peripherals you are attaching to the BT45C should be SCSI-2 Com- mon Command Set (CC9 compatible. n PC-DOS or MS-DOS n IBM OS/2 or MS-OS/2 Software Requirements n NextStep You need the following software: Device Driver Needs n Software for hard drive set-up to perform partitioning and high-level Device drivers are needed to alIow devices attached to the adapter to be formatting recognized by and operate with the operating system. In some cases, the H Operating system software for hard drives being installed operating system has embedded or built-in support for basic hard drive # Device drivers as described below configurations. This means you can install up to a specific number of hard drives without having to install additional device driver software. If you are installing other types of devices, such tape backup device or a scanner, you will need to install device drivers to support those devices. These drivers either come with the operating system, are packaged with the device, or are available from third-party vendors. n l 1-2 Introduction 1-3Introduction as a BF445C The Figure Connector ExEY~l .ED Reference Documents You should have the following documents on hand during installation: The installation and set-up guide for your computer The installation guide for your SCSI peripherals (e.g., hard drive, CD-ROM or tape drive) Operating system installation and user’s guide Installation guide for or third-party device drivers (if applicable) Host adapter installation involves the following steps: x x Dimensions:Unpacking the host adapter and opening up the host system for adapter installation.

A failure most likely indicates that there is a problem in the configu- ration between the host system and the adapter. Use the Fom?at Disk option on the AutoSCSI Utilities Menu to low-level format your SCSI hard disk drive. Because most off-the-shelf hard drives are factory formatted, it is unlikely that you need to perform this proce- dure. If, however, you have an un-formatted disk, or if you are experienc- ing problems with your hard drive that indicate the need for a low-level format, use this option. Once formatting is complete, run the Verify Disk option on the Utilities Menu to check the results of the format. Both options are described in the following section. Warning: The format will erase all data on your disk drives. Before formatting make sure that all necessa y data is backed up on another drive. 3-14 n Adapter Configuration I 4-l SetupHard Drive Select the desired device and press .
