Complexes, Planars, and ADF Definitions

Type 4 Refdisk Planar ADFs

These definitions reflect what Micro Channel features are supported by a given processor complex. The definitions are used by some ADF files to allow/disallow a certain adapter features to be turned on (otherwise they are always off).

95A DE4FE.ADF

N, or P / Q / Y

"I_100ns_Stream_Data" = 1
"I_Data_Parity" = 1
"I_Address_Parity" = 1
"I_Sel_Fbk_Rtn" = 1
"I_Chan_Chk_Ex_Rpt" = 1
"I_Match_Memory" = 1

Note: Type 0 through 3 complexes are NOT supported on the 95A planar.

* Sub-model ID 3Ah is currently unknown.

I_Data_Parity: "Data Parity Exception Handling" - If supported by the system, certain adapters can generate and detect data parity on Micro Channel.

I_Sel_Fbk_Rtn: "Selected Feedback Return Exception" - If supported by the system, certain adapters can use use the Micro Channel Selected Feedback Return Exception feature.

I_100ns_Stream_Data: "100ns Streaming Data Transfer Support - If supported by the system, certain adapters can use the 100 ns Streaming Data Micro Channel protocol, which provides better performance on the Micro Channel.

Note: The other definitions don't seem to be used in any of the available ADFs.
