You can disable the SD card interface if you don't need it.
You have to rename one key in the registry:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SDIO] "Dll" = "libnvsdio.dll"
Rename the key value to "_libnvsdio.dll".
You have to rename two keys.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SDBusDriver] "Dll" = "SDBus.dll"
Rename the key value to _SDBus.dll
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SDHC] "Dll" = "colibri_sdhc.dll"
Rename the key value to _colibri_sdhc.dll"
Save the registry after you have done the changes.
