You just have to use sp_configure:
EXEC sp_configure 'show advanced option', '1';
RECONFIGURE;
EXEC sys.sp_configure;
That will show you all the advanced options to just see the affinity mask for I/O you do this:
EXEC sys.sp_configure @configname = 'affinity I/O mask';
--or
EXEC sys.sp_configure @configname = 'affinity64 I/O mask';
