Pre-Defined Resources for AdvancedMC Modules
The AdvancedMC is hot swappable. In order to support AdvancedMC hot add, the
MPCBL0050 SBC has to reserve resources that are not being used by a device when the
SBC is booted. It is not possible for the SBC to know exactly what resources an
AdvancedMC module that is hot added may require before it is inserted. If the
resources reserved by the SBC for the AdvancedMC module are adequate, then the
AdvancedMC hot add will be successful. If an AdvancedMC module needs more
resources (memory, I/O space, etc.) than the SBC has reserved, then the AdvancedMC
module will not work properly until the SBC is rebooted with the AdvancedMC module
installed. If the hot added AdvancedMC module does not use all of the resources that
are reserved by the SBC, then the reserved resources are left unused and cannot be
used by another device because they are still reserved.
On the MPCBL0050 board, the EFI BIOS reserves the following resources for the
AdvancedMC hot plug slot:
• Bus = 5
• I/O space = 8 KB
