5 2 Getting Started Host Adapter and the SCSI Bus I/OHIGHWAY is a bus mastering host adapter which works with the host computer to provide control for the SCSI bus. By daisy chaining peripheral devices together, up to seven devices can be linked with I/OHIGHWAY. The host adapter can be placed in any standard PCI slot on the bus. SCSI bus preparation Each peripheral device attached to the SCSI bus can either be an internal or external device.
6 Getting Started I/OHIGHWAYs SCSI termination can be set to auto-termination or programmable mode via the SmartSCSI Setup Utility. This feature allows the operator to switch the autotermination On or Off. If auto-termination is switched off, the operator can manually program termination for the host adapter. There are three ways to manually control terminating the host adapter on the SCSI bus (see TABLE 1).
7 3 Hardware Installation Installation Basics The internal cable permits connection of multiple internal devices. SCSI devices that are connected to the internal connector are installed inside the host computer enclosure. The external connector is accesible through the D-shell connector at the back of the host system and is designed to connect devices outside the host system enclosure. The following table has connector details of I/OHIGHWAY.
8 Hardware Installation 3 Inserting the host adapter Orient the host adapter for installation so that the external connector is facing the back of the system unit and align the card with the PCI connector on the system unit (see FIGURE 3). Holding the adapter by the mounting bracket and the card edge, match up the card edge connector with the PCI host computer socket and insert the card into the socket.
9 Hardware Installation When attaching FastSCSI devices, use the 50-pin FastSCSI cable connector on the host adapter. Align the internal cable into the host adapter and the other cable connectors in a similar fashion into the other SCSI device connectors as described in the appropriate manufacturers instructions. FIGURE 4 Connecting the 50-pin internal flat ribbon cable 4b Installation of external SCSI cables Installation of external SCSI cables can be performed after the cover has been closed.
10 Hardware Installation 5 Drive activity LED A drive activity LED is designed into the host adapter to indicate when a data transfer is being made. Connection to the LED is optional and cabling is not included with this kit. Each host adapter has one four-pin connector. Please refer to the host adapters illustration (FIGURE 1) for the LED connector that will accomodate the LED cable. 6 Multiple Initiators Under some circumstances multiple initiators can be used on a single SCSI bus.
11 Hardware Installation 9 System startup The newly installed SCSI bus is now ready to power up. Switch on peripheral and host computer system power. The system monitor should display the following information, but may vary, based on the system BIOS manufacturer. The normal Power-On Self Test and memory test procedure. The host adapter sign on message including a list of attached SCSI devices. The list should match the peripheral devices attached to the bus.

13 4 Host Adapter Setup Running the SmartSCSI Setup Utility To start the SmartSCSI Setup Utility, verify that all devices attached to the SCSI bus are powered up when the host computer system is turned on. Once the power switch has been turned on and the system begins its on screen power up sequence, the Initio banner will be displayed for a brief period. During this time the Initio SmartSCSI Setup Utility is accessible by pressing the key and the key at the same time.
14 Host Adapter Setup DOS Space > 1 GB. Using this option allows for single disk capacities to be extended up to 8 GBytes (yes). Please refer to the Appendix titled DOS Space > 1 GB for further information on this feature. (NO) DOS limits the number of cylinders per drive to 1024. The host adapter defines head and sector usage to 64 heads and 32 sectors. This format allows for maximum capacity of 1 gigabyte per disk storage.
15 Host Adapter Setup SCSI Parity Check ON. Select this option to enable or disable parity checking on the SCSI bus by the host adapter. The default setting for this option is on (yes). NOTE: If this option is set ON, be certain that the peripheral SCSI device also has this option turned ON. BIOS Setup Enable Host Adapter BIOS. This option controls the host adapter usage of SCSI disk I/O routines inside the host adapter BIOS.

20 MS-DOS/Windows 3.1x Driver Installation are 1-9 and D or d. The D or d values are used to Disable the time out mechanism. If the time out mechanism is disabled then faulty hardware can lock up the system. Examples: /T4 /Td /TD /T1 /X /x This option is used to exclude particular CD-ROM drives. Excluded CDROM drives are identified by specifying the host adapter, target id and lun. These values are spereated by a colon. Groups of CDROM drives (or wild cards) can also be identified.
21 MS-DOS/Windows 3.1x Driver Installation ASPI Disk Driver Command Line Options INIDISK.SYS is a DOS block device driver for supporting SCSI fixed disks, removable disks and MO devices. INIDISK.SYS is automatically loaded in CONFIG.SYS start up file by the Initio DOSSETUP or SETUP programs. INIDISK.SYS requires that the Initio ASPI Manager be loaded. INIDISK.SYS can be loaded with either the DEVICE= or DEVICEHIGH= command. INICD.SYS can be found on the INI-9XXXU/9XXXUW DRIVER DISK 1.
22 MS-DOS/Windows 3.1x Driver Installation /X0 This will exclude ALL drives on Host Adapter 0. SAMPLE CONFIG.SYS These samples assume that the user has loaded the Initio drivers in the following directory: c:\iniaspi. Config.sys: DEVICEHIGH=c:\iniaspi\aspi910u DEVICEHIGH=c:\iniaspi\inicd.

51 Troubleshooting In the following section you will find commonly asked questions and answers to problems encountered during the installation of your host adapter. Question: Answer: Why isnt the INI-9XXX banner !!! Press for SmartSCSI Setup Utility !!! displayed when I power up the host system? Verify that all cabling to the host adapter is installed correctly, refer to the hardware installation section of this manual.
52 Troubleshooting Consult the SCO UnixWare Installation Handbook Troubleshooting section to help isolate the problem. If it becomes necessary to remove the Initio device driver, please consult the Removing the Initio Driver from a SCO UnixWare System section of this document. B: DOS Space > 1GB The default disk head mapping for Initio SCSI host adapter is 255 heads and 63 sectors. This translates to a maximum accessible capacity of 8 GBytes per drive under MS-DOS.
53 Troubleshooting Drives with Multiple Operating Systems It is mandatory that the same head mapping be used across multiple operating systems on one drive. However you can use different head mappings on different drives with the exception of SCO UNIX. It is recommended that you enable DOS Space > 1GB option if the capacity of your SCSI hard disk has more than 1 GByte.
