NOTE: All MCA adapters use devices.mca.8f97.*, does this mean that they are all similar?

Notes The 6215 and 6219 adapters appear to be essentially identical other than the fact that the 6215 is PCI and the 6219 is MCA (they both take the same microcode and appear to have identical functionality).

Availability of TMSSA support may depend on what version of microcode is on the adapter (the 6215 and 6219 adapters require at least level 1801).

The Advanced SerialRAID Adapters (6225 and 6230) are capable of 40MB/sec per direction per loop. The other adapters are capable of 20MB/sec per direction per loop.

Many of the values in the above table assume that the adapter has sufficiently current microcode.

The Advanced SerialRAID Plus Adapter Planning Guide states:
The Advanced SerialRAID Plus Adapter has code above level 7600. The Advanced SerialRAID Adapter had code below 7600 and that adapter can be converted to support the additional functions by downloading code above level 7600.

i.e. the adapters are identical if they have sufficiently recent microcode. This would seem to explain why the 6225 and the 6230 both are type 4-P.
