Preconfiguration Information
If your BT-946C PCI card is labeled Rev. A or B, it needs to be supported in ISA
emulation mode; use I/O address 0x334.
Note - To find the revision level of a BusLogic PCI card, look at the card itself. The
revision of the card is not provided in the manufacturer’s documentation.
If your BT-946C is labeled Rev. C, it can be supported in native PCI mode. To do
this, select “Advanced option,” and choose “NO” for the “Host Adapter I/O Port
Address as default” option.
If your PCI card is model BT-956C or model BT-946C Rev. E, it can also be
supported in native PCI mode. To do this, disable the “Set ISA Compatible I/O
Port (PCI Only)” option.
Since your BusLogic board model ends in “C”, you must enter the AutoSCSI
configuration utility and check the termination.
Supported Settings
• IRQ Level: 5, 6, 7, 8, 9, 10, 11, 12, 14, 15
• I/O Address: 0x334, 0x230, 0x234, 0x130, 0x134
Note - I/O addresses are dynamically configured for BT-946C Rev. C PCI adapters.
