Configuring Multiple Devices

Follow these guidelines when adding a second Mylex PCI controller to a system.

• The already installed PCI board must be the primary controller.

• The primary controller must have an I/O address that precedes the secondary controller in "Supported Settings" (as listed from left to right). For example, the primary controller can use an I/O address of 0x234, as long as the secondary controller uses either 0x130 or 0x134. The I/O address of each board is determined by its slot. Try different slots until the first card works as the primary controller.

• Disable the BIOS on the secondary controller.

• Wide-mode PCI adapters will support targets greater than 7 if the proper entries are added to the system configuration files: /kernel/drv/sd.conf (for disk) and /kernel/drv/st.conf (for tape).
