Note - I/O addresses are dynamically conﬁgured for BT-946C Rev. C PCI adapters.

Known Problems and Limitations

Using an I/O address of 0x330 causes the Solaris aha driver to be selected instead

of blogic native mode drivers. These cards have not been tested in Adaptec

AHA-1540 mode.

Do not run the drvconfig utility during heavy I/O involving disks and tapes

because doing so can cause data overrun errors.

Data overrun errors may occur under high stress when your system is conﬁgured

with multiple disks.

If problems occur during Solaris installation, set the Interrupt Pin number of the

“Conﬁgure Adapter” option in the manufacturer’s AutoSCSI utility as follows:

Slot Interrupt Pin

For more information, see the sections “Conﬁguration for Non-Conforming PCI

Motherboards” and “Handling Motherboard Variations” in the documentation that

comes with your board.

Early versions of Rev. A, B, and C of the BT-946C may not work with the Solaris

operating environment.

Upgrade to at least Firmware 4.25J, BIOS 4.92E, and AutoSCSI 1.06E, if you have

BT946C Rev. B. Upgrade the controller to at least BT946C Rev. E.

Conﬁguration Procedure

BT-946C, Rev. A and B Only

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.

Put the adapter in ISA-compatible mode by setting the value for “Set Host Bus

Adapter I/O Port Address as Default” to No.
