Configuration Procedure

BT-946C, Rev. A and B Only

Insert the board into the bus master slot, and using the AutoSCSI utility:

• If the boot disk is larger than 1 Gbyte, set the "Adapter BIOS Supports Space > 1 GB (DOS) only" option to Yes.

• Put the adapter in ISA-compatible mode by setting the value for "Set Host Bus Adapter I/O Port Address as Default" to No.

• Ensure the Advanced option "BIOS Support for > 2 Drives (DOS 5.0 or above)" is set to No.

• Configure the IRQ and BIOS address values manually if your PCI motherboard is not fully PCI-specification compliant. If the system hangs while installing the Solaris software, do the following:

  • Check the IRQ jumpers on the motherboard, if any.

  • Run the CMOS utility to set the IRQ and BIOS addresses, if any.

  • Run the AutoSCSI utility.

  All the settings should match each other. If you need to manually configure the BIOS address, you may have to check jumpers JP4 and JP5.

BT-946C (Rev. C) and BT-956C

Insert the board into the bus master slot, and using the AutoSCSI utility:

• If the boot disk is larger than 1 Gbyte, set the "Adapter BIOS Supports Space > 1 GB (DOS) only" option to Yes.

• Choose the defaults, except set the 5.1 "BIOS Support for > 2 Drives (DOS 5.0 or above)" to No.

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).
