capable of 38-bit addressing is installed in the workstation.

FIXES: 
- Corrects an issue that prevents proper system shutdown when certain PCI-X 
cards are installed in the workstation.
- Fixes an issue that could lead to occasional false fan failure messages.

first SATA optical storage drive. This issue can occur only when multiple SATA 
optical storage drives are installed.
