In cases where a drive has been used with other host adapters the drive should have a low-level format performed.
Host Adapter Setup This Chapter Is About • How to start the SmartSCSI Setup Utility • Description of SmartSCSI features 4-1
Host Adapter Setup Configuring the host adapter The INI-9100U/9100UW host adapter is a plug and play host adapter which eliminates the need to toggle switches for the host adapter to function in PCI plug and play systems. Once the host adapter has been installed into the host computer system it is not necessary to remove the host computer’s cover if changes are made to your system configuration. The SCSI bus protocols that your system requires are set by SmartSCSI.
Main menu options The main menu provides five possible setup options for meeting your system configuration. • • • • • Scan Bus Device Setup Adapter Setup BIOS Setup Disk Utility Scan Bus This option scans the SCSI bus. All device ID’s are displayed on the screen including SCSI ID’s without devices attached. This allows for a better definition of location and priority on the SCSI bus. • • A device ID should only be changed if it conflicts with another device address on the same bus.
Maximum Synchronous Transfer Rate. This option determines the speed at which data is moved across the SCSI cable. The INI-9100U has the option of running up to 20 MBytes per second and the INI9100UW has the option of running up to 40 Mbytes per second. (20) 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.
Enable Disconnect. The host adapter uses this option to allow a device to temporarily disconnect from the SCSI bus (referred to as disconnect/reconnect). This allows the host adapter to perform other functions on the bus while the device is temporarily disconnected. The device and the host adapter can then reconnect when the bus is needed. (yes) Enable Wide Negotiation (INI-9100UW ONLY). This option determines whether the host adapter initiates wide data transfer with the specified SCSI device.
Host Adapter Setup Host Adapter SCSI Bus ID. Used to change the adapter’s SCSI ID on the SCSI bus. The INI-9100U provides eight ID’s available numbered 0-7, with 7 having the highest priority. The INI-9100UW provide sixteen ID’s available numbered 0-15, with 15 having the highest priority. The default ID is 7 for the INI-9100U/9100UW. Installation of additional host adapters is permitted on the same PCI bus. This will allow the system to have more than one SCI bus attached.
BIOS Setup Enable Host Adapter BIOS. This option controls the host adapter usage of SCSI disk I/O routines inside the INI-9100U/9100UW BIOS. By disabling this option you will eliminate the host adapter’s ability to utilize boot capabilities in the INI-9100U/9100UW. Setting this to “no” will also disable all subsequent features displayed by this onscreen panel. (yes) BIOS Support For More Than 2 Drives. This option supports 2 or more disk drives on the SCSI bus for MS-DOS 5.0 or later when enabled.
Disk Utilities Format Disk. Use this option to perform a low level disk format on the target device. The format will erase all data resident on the targeted disk drive. Refer to the section titled “Hard Drive Preparation” for additional information. Verify Disk. This option will verify the media of a successfully formatted device and verify that the drive is functioning properly. Verify will also identify and flag any bad sectors on the disk so that during operation these flagged sectors will not be used.

SCO UnixWare Driver Installation Overview The Initio SCO UnixWare device driver will support UnixWare 2.x. The device driver is transferred from the floppy diskette to the hard drive where it is loaded during system initialization. The installation of Initio device drivers to support SCO UnixWare may be found on the INITIO INI-9100U/9100UW DRIVER DISK 2. Reference Documentation: • SCO UnixWare Installation Handbook.
• Host adapter interrupt level must be set to IRQ 10 for proper installation of the Initio driver. Please refer to your system documentation to set the interrupt levels and your peripheral documentation for help in setting SCSI IDs. Installing the Initio driver in a new UnixWare system Drivers for the Initio host adapter may be found on the INITIO INI9100U/9100UW DRIVER DISK 2. In most cases you will load the drivers during a new installation of UnixWare from CD-ROM.
2. When prompted to INSTALL HOST BUS ADAPTER DRIVERS (see figure 11-2), insert the “INITIO INI-9100U/9100UW DRIVER DISK 2” into drive A: press . figure 11-2 Install Host Bus Adapter Drivers 3. When prompted to INSTALL ANOTHER HBA DISKETTE (see figure 11-3), press to continue.
figure 11-3 Install another HBA Diskette 4. Follow the directions on screen until you come to a window titled: Loading Initio INI-9100U/9100UW Host Adapter. • • 5. Select CONTINUE INSTALLATION. Select CONTINUE INSTALLATION again. This completes loading the host adapter driver. Follow the on-screen directions to complete the SCO UnixWare installation. For further information regarding UnixWare installation, refer to the SCO UnixWare Installation Handbook.
Adding the Initio driver to an existing UnixWare system 1. Once a UnixWare session is established and a command prompt is ready, type (recall that UnixWare is case sensitive): • cp /stand/unix /stand/unix.org , press • pkgadd -d diskette1 , press 2. Select i910u ihv hba from the list of available host drivers, press . 3. If the INI-9100U/9100UW is intended to be the bootable host adapter, the next step to updating the driver will require a revision to the I910u file.
4. If the INI-9100U/9100UW is NOT intended to be the bootable host adapter, these instructions will guide you through changing the current software settings for UnixWare to establish the INI-9100U/9100UW as a non-bootable host adapter for your device: • 5.
Removing the Initio driver from a UnixWare system 1. Once a UnixWare session is established and a command prompt is ready, type (recall that UnixWare is case sensitive): • Type: /etc/conf/bin/idinstall -d i910u following files: to delete the /etc/conf/mdevice.d/i910u /etc/conf/sdevice.d/i910u /etc/conf/pack.d/i910u/driver.o /etc/conf/pack.d/i910u/space.c /etc/conf/pack.d/i910u/disk.cfg 2.
Appendix This Chapter Is About • Troubleshooting • DOS Space > 1 Gigabyte • Warranty 12-1
A: Troubleshooting In the following section you will find commonly asked questions and answers to problems encountered during the installation of the INI-9100U/9100UW. Question: Why isn’t the INI-9100U/9100UW banner “!!! Press for SmartSCSI Setup Utility !!!” displayed when I power up the host system? Answer: Verify that all cabling to the host adapter is installed correctly, refer to the hardware installation section of this manual.
Question: Under SCO UnixWare, the system displays a panic message or crashes during bootup: Answer: Reboot the system and verify that the INI-9100U/9100UW is using IRQ10. Please Refer to your system documentation to set the interrupt levels and your peripheral documentation for help in setting SCSI ID’s. In order to boot from the old UnixWare kernel, reboot the system and execute the following steps: • • • • Begin an interactive boot session by pressing the at the BOOTING UNIXWARE prompt.
B: DOS Space > 1GB The default disk head mapping for Initio SCSI host adapter is 64 heads and 32 sectors. Under this configuration, the MS-DOS limit is 1024 cylinders per drive. This translates to a maximum accessible capacity of 1 GBytes per drive. By changing the head mapping to 255 heads and 63 sectors, the "DOS Space > 1GB" option can support disk capacities up to 8 GBytes under MS-DOS.
SCO UNIX can not support different head mappings for each disk drive under the same host adapter. The head mapping will be based on the setting represented by target ID 0. 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.
