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 BusLogic 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:

Set the “Adapter BIOS Supports Space > 1 GB (DOS only)” option to Yes if the

boot disk is larger than 1 Gbyte.

Choose the defaults, except set the 5.1 “BIOS Support for > 2 Drives (DOS 5.0 or

above)” to No.

Special Cases

Conﬁguring Multiple Devices

Follow these guidelines when adding a second BusLogic 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 (for disk), and

/kernel/drv/st.conf (for tape).
