Table 10: I/O space requirement
*1) WinPE does not require I/O space but some drivers require I/O space for
loading properly.
*2) When both Legacy OPROM and EFI driver are available, the BIOS loads the
EFI driver and the Legacy service is provided by the CSM module, that is the
Legacy OPROM is not loaded.

I/O space limitation

The I/O space is limited to 64 KB. Each PCI Bridge assigns its I/O space in
several blocks of 4 KB. ICH10 requires 1-block for Legacy support.
Auto and Disabled can be selected in the BIOS setup menu to assign I/O space
for onboard devices and for PCIe slots including slot #8 for the Modular RAID
controller. Auto is set for all onboard devices and PCIe slots by default.
