VI. ASUS PCI SCSI Cards VI. ASUS SCSI Cards (SCSI BIOS) Symbios SCSI BIOS and Drivers Aside from the system BIOS, the Flash memory chip on the motherboard also contains the Symbios SCSI BIOS. This Symbios SCSI BIOS works in conjunction with the optional ASUS PCI-SC200 controller card to provide Fast SCSI-2 interface when using compatible SCSI devices or the ASUS PCI-SC860 SCSI controller cards to provide Ultra-Fast SCSI-2 interface when using Ultra-Fast SCSI-2 devices.
VI. ASUS PCI SCSI Cards VI. ASUS SCSI Cards (Setup) Setting Up the ASUS PCI-SC200 & PCI-SC860 There are two jumper settings you may need to make on the ASUS PCI-SC200 to set it up. One setting assigns the PCI INT interrupt, the other sets the card’s termination. The ASUS PCI-SC860 has no jumper settings but you should read the “Terminator Requirements.” Setting the INT Assignment for the ASUS PCI-SC200 You must use PCI INT A setting in order to properly assign the ASUS PCI-SC200's interrupt.
VI. ASUS PCI SCSI Cards VI. ASUS SCSI Cards (Jumpers) Terminator Settings for the ASUS PCI-SC860 Many SCSI devices including the ASUS PCI-SC860 use a set of onboard active resistors to terminate the devices at the ends automatically. Automatic termination requires that the SCSI devices be connected in a straight linear connection or “chain.” Connect SCSI devices to one or two of the SCSI connectors in a linear “chain” for auto termination of the ASUS PCI-SC860 to be effective.
