Introduction

The intent of this document is to address the manufacturing issue related to the Peripheral
Component Interconnect Express (PCIe) Option ROM settings as seen on some Cisco C220 M4
and C240 M4 servers. A number of the C-Series servers have shipped to customers with the
incorrect PCIe Option ROM settings, preventing them from booting to many PCIe based devices
(Including but not limited to RAID Controller / Serial-Attached SCSI (SAS) Host Bus Adapter
(HBA), Modular LAN on Motherboard (MLOM) or other networking cards or HBAs. The instructions
below will assist you in resolveing customers impacted by this.

Potentially Impacted Systems (~11000 servers):

C220 M4: Systems shipped between Feb 14th and Mar 28th
C240 M4: Systems shipped between Feb 14th and Mar 28th

Customer Visibility/Impact:

Customers are unable to boot from any PCIe Slot based device, as the "All PCIe Slots
OptionROM" flag has been disabled. Customers will need to toggle this BIOS token, and can do
so using any of the workaround methods mentioned below.

Work-Around Options:

Work-Around #1 (Recommended):

Log in to the IMC, and navigate to the Summary / BIOS / Configure BIOS / Advanced Tab as
shown below.

Set the “All PCIe Slots OptionROM” flag to “enabled”. Save changes and REBOOT the host.

Work-Around #2:

Connect crash cart / launch vKNM to the system. Power the system on and use the F2 menu to
set the “All PCIe Slots OptionROM” flag to ENABLED.

Navigate to the Advanced LOM and PCIe Slots Configuration tab, and press ENTER1.

Scroll down and set the "All PCIe Slots OptionROM" to ENABLED2.
