I am recieving a number of these errors in the System Event log after a reboot.  The server is a W2K3 SP2 PowerEdge 6650.

Event Type: Error
Event Source: ql2300
Event ID: 11
Description:
The driver detected a controller error on \Device\RaidPort1.

The QLA2340 HBA's rev levels:

Driver: STOR Miniport v9.1.4.15
BIOS: v1.52
Firmware: v3.03.21

Can I just update the driver to v9.1.7.18 and be done with it or do I need to update the flash and NVRAM also?  If I need to update the flash and NVRAM where do I obtain the BIN and DAT files?
