[BioC] The mis-match platform read by bioconductor --> MOE430B

I am wondering how does the bioconductor know what platforms the .cel
files come from when reading the raw data by using eg. ReadAffy() or
I have several raw .cel files downloaded from GEO, and they are
supposed to be from the MOE430B, however, when I used either
ReadAffy() or justGCRMA(), I received this error:
Error in read.affybatch(filenames = l$filenames, phenoData = l$phenoData, :
Cel file /GSM79006.CEL does not seem to be of MOE430A type
I tried different samples that also used MOE430B, and each of them
gives the same error.
The .cel file is similar to this:
DatHeader=[2..44430] A40200B_++:CLS=4733 RWS=4733 XIN=3 YIN=3 VE=17
2.0 06/24/04 11:23:43 HP MOE430B.1sq 6
As you could see, it specifies MOE430B, but I 'm not sure how the
bioconductor figured that this is a MOE430A , and gives the error..
I greatly appreciate for any comment of suggestion.
Thanks a lot,
