Ultra bay for R51 SAME AS a20M?

[spuddog]

I'm looking at a R51, the cd-drive is listed as an ultrabay is that the same as an ultra bay2000. If not can I swap rails and adapters to use my present cdrw? I know you can't give me a definitive answer without all the specifics, but any info would help.

Thanks

A22m uses Ultrabay 2000. R51 uses Ultrabay Enhanced.

A22m drives cannot be used in R51. The other way is possible through an adapter.
