[BioC] pm or mm methods for AffyBatch object

I have two questions:
I have a chip which is the same feature as u133A, however have much less mm
probes. When using pm or mm method, the matrices have the same dimension. I
wonder, do the methods assume the number of probes for pm or mm are the
sames by default? How do you determine pm or mm probes?
The cdf I am using is the same size as u133A(I wish I could contribute my
cdf), I only read in 5 chips. However running into memory problem quickly.
For example, I did a boxplot on 5 chips, it gave memory error (I allocated
1G) after 10mins of plotting.
Could somebody give me some tips besides breaking down the files (since I
only have 5 files)?
