x86: PXE Network Installation Hangs on Systems With Adaptec Ultra-160 SCSI Interface (5039573)

If you use the Intel Preboot Execution Environment (PXE) to perform a network installation on a system with an Adaptec Ultra-160 SCSI interface, the installation hangs. An error similar to the following message might be displayed:

Error: Unable to Find Device Driver
The device driver, cadp160.bef, is missing.

In the previous example, the cadp160.bef driver is not found on the system. The name of the affected driver might differ on your system.

This error occurs if the system BIOS sets the Adaptec Ultra-160 interface to use the same interrupt request (IRQ) as the system network interface card (NIC).

Workaround: Choose one of the following workarounds.

• To install over the network, remove the Adaptec Ultra-160 SCSI interface, and perform an installation over the network with PXE.

• Install from the Solaris 9 9/04 DVD or CDs .
