[. . . ] Ensure that the positive lead of the LED cable (usually a red wire or marked with a red stripe) is attached to pin 1 or 3 and the negative lead (usually a black wire) is attached to pin 2 or 4. If you are using the internal SCSI cable, connect this cable to the controller. Install the controller in an available 32- or 64-bit PCI bus slot and secure the controller bracket to the host system cabinet with the screw provided. In a system with multiple controllers, the controller that has the lowest BIOS ROM address (typically, the lowest numbered PCI slot) will become the booting controller. 3-6 HP 2100S SCSI RAID Controller User Guide Installing Your Controller 6. Connect any external cables to the controller. IMPORTANT: If you have disk drives attached to a SCSI controller with a Symbios chipset, use SMOR to set the Bootable Devices option to Disable. Determining the Booting Controller Adaptec SCSI RAID controllers are shipped with an Adaptec I2O BIOS ROM enabled for PCI assignment. This ROM BIOS intercepts and processes Int13 BIOS calls with an embedded DOS driver. The Adaptec I2O BIOS ROM can be disabled or the address changed automatically by the system's Plug-and-Play BIOS. In systems with multiple controllers, the first I2O controller found during boot loads its BIOS and installs all of the Adaptec hardware on the system. Any additional Adaptec I2O controllers that are found automatically detect the presence of the first controller and disable their BIOS code. The disk controller that has the lowest BIOS ROM address (typically, the lowest PCI slot number) will become the booting controller. Ensure that the Adaptec ROM occupies the lowest address if you want the Adaptec controller to be the booting controller in a system with controllers from multiple manufacturers. Some system BIOS manufacturers select the smallest add-in BIOS as the first candidate, therefore slot selection has no effect on which adapter BIOS loads first. In this case, you need to disable the BIOS on selected adapters to control which adapter is the boot controller. This procedure can also be helpful in situations where it is physically difficult to manage the slot order. Controller IRQ and Address During the host system boot process, the host system BIOS should automatically configure the Adaptec I2O BIOS interrupt level (IRQ) and memory location for all Adaptec PCI controllers in the system. If problems occur, refer to Appendix C, "Troubleshooting, " for additional help. HP 2100S SCSI RAID Controller User Guide 3-7 Installing Your Controller NVRAM Reset Adaptec SCSI RAID controllers retain their setup parameters even when powered off. These parameters are stored on the controller in an area of nonvolatile memory (NVRAM). There is a possibility that, through improper configuration, the controller can be put into a state where it hangs the system during boot. If this happens, the parameters stored in the NVRAM can be restored to their default settings by the following procedure: 1. Place a shorting jumper across pins 1 and 2 of P4 on the controller. For the location of P4 on your controller, refer to "Board Layout" in Chapter 2, "About Your New Controller. " 3. Power on the system and wait until LEDs 3, 5, 7, and 8 on the controller begin flashing. [. . . ] However, during boot, the Adaptec I2O BIOS message appears first which indicates that a drive attached to an Adaptec controller will be the boot drive. Solution 10 Use SMOR to disable the Boot Enable parameter for that controller. This will prevent the Adaptec controller from being used as the booting controller for system. C-6 HP 2100S SCSI RAID Controller User Guide Troubleshooting Problem 11 The Adaptec SCSI RAID controller I2O BIOS reports the drive as a disk instead of a drive. Solution 11 This typically happens when a drive that is attached to an Adaptec SCSI RAID controller has been formatted with a sector size other than 512 bytes. Use SMOR to reformat the drive with 512-byte sectors. This can also occur if the drive is the 9th or higher logical drive attached to the controller. IMPORTANT: Using SMOR to set Bootable Devices to Disabled as in the previous problem will result in the same symptoms. [. . . ]
