.1 SCSI Communication
7.8
he DEVICE definition block supports SCSI communication with the INICI03.
When a device block is configured, OPC90 will automatically detect the currently
installed SCSI bus adapter(s) and search each adapter bus for INICI03 devices.
Detected devices will appear in the primary and secondary port list boxes that
are part of the DEVICE block properties. They are listed as devices like S0001:,
S0002: etc. The ‘S’ indicates SCSI followed by the adapter card number,
adapter bus number, adapter logical unit number and INICI03 SCSI target ID.
Note that the target ID is the value set by switches on the Bailey INICI03
INICI03A module. The INICI03 must be powered up, configured to utilize its
SCSI communication channel and attached to a PC SCSI host adapter card.
Just about any PC SCSI card that supports external connection to the INICI03
IMMPIO1 module’s 50 pin SCSI socket should work ok with the exception of
cards designed for use as raid controllers. RoviSys validated SCSI
communication using Adaptec model 2930, 29160 and Domex model 3194U
SCSI controller cards.
Note that for PCIX based PCs, the Adaptec 29320A does not work, use the
29160.
Adjustment to the SCSI BIOS might be necessary. The BIOS setup can be
configured when the PC is booting. Following are general guidelines for typical
settings. Depending on the type of SCSI card, all of these settings or the
terminology might be different.
* SCSI Parity Checking: Enabled
* Host Adapter SCSI Termination: Automatic
* Initiate Sync Negotiation: Yes (IDs 0 - 7)
* Max Sync Transfer Rate: 20 MB/Sec (IDs 0 - 7)
* Enable Disconnect: Yes (IDs 0 - 7)
* Send Start Unit Command: No (IDs 0 - 7)
* BIOS Multiple LUN Support: No (IDs 0 - 7)
* Include in bios scan Yes (IDs 0 - 7)
* Plug and Play SCAM support: Disabled
* Reset SCSI Bus at IC Init: Disabled
* Extended bios Translate for DOS ICs: Enabled
* BIOS support for Int 13 extensions: Enabled
Depending on the operating system, OPC90 utilizes the Advanced SCSI
Programming Interface (ASPI) or SCSI Pass Through Interface (SPTI) to
communicate with the INICI03 via the host controller driver. If your system does
not have ASPI it can be loaded by double clicking on the ASPI32.EXE file
installed in the same directory as OPC90. Do NOT install ASPI32.EXE with
