I'm attempting to write a driver for the Buslogic (originally made by Tekram) series of mirroring IDE cacheing controllers (http://www.tekram.com has the best info on them). What I need to ask is this: how do I go about talking to the hardware to figure out what vendor specific commands it has? I tried using the promise dc4030 driver but the detect fails (as it should, after looking at the code). Yes, I tried getting the info from Tekram, but they told me that they didn't have the information. |
