Chapter 9 

BIOS/Firmware Considerations 

 
 
While OPMA attempts to minimize impacts on existing BIOS, any form of the MegaRAC card 
cross-platform compatibility requires some degree of system BIOS support. The main reason for 
OPMA specific BIOS support is to enable simple plug and play capability. Under normal 
circumstances, the BIOS should not halt the boot process or require keystroke input on any sort of 
BMC related error; the absence of the MegaRAC M300V card should never stop a server from 
booting up. Any reference in the following paragraphs to BIOS printing messages to the boot 
screen should be taken to mean that BIOS must write the indicated message to the text-based 
BIOS POST screen that is displayed during POST. 
 

MCard Presence Detect 

 
BIOS must be capable of identifying the presence/absence of the MegaRAC M300V card. This is 
done by monitoring the MCARD_PRESENCE_L signal using a BIOS-controlled GPIO that is 
typically implemented using the system Southbridge chip. If the GPIO is not available directly 
from the chipset, the system must use an alternative solution to read this signal from the 
MegaRAC M300V card (for example, an SMBus based GPIO expander).  
 
If the MegaRAC M300V card is found to be present, the BIOS then determines which IPMI 
interface to use for sending IPMI commands. BIOS and other system software reads the card 
detect signal and then determine the MegaRAC M300V card presence. 
 

Card Detect Signal States 

 

Card Detect State 

Meaning 

Asserted (Low) 

The MegaRAC M300V card is installed in the OPMA 
connector. 

Deasserted (High) 

No mCard is installed in the OPMA connector. 

 

MCard IPMI Command Interface Type Detection 

 
The BIOS must be capable of determining which IPMI interface the MegaRAC M300V card 
supports. This is done by monitoring the MCARD_INTERFACE_ID0–CARD_INTERFACE_ID2 
signals using BIOS-controlled GPIOs that are typically implemented using the system Southbridge 
chip. If the GPIOs are not available directly from the chipset, the system must use an alternative 
solution to read the signals from the MegaRAC M300V card (for example, an SMBus-based GPIO 
expander).  
 
The value read back from the INTERFACE_ID signals indicates the default IPMI 
communications interface supported by the management controller. In cases where the MegaRAC 
M300V card supports more than one IPMI interface, these additional interfaces are conveyed 
through an IPMI OEM command. BIOS or system software can decide at runtime which interface 
to use for IPMI communications.
