You may already have this information, but in case this info will be useful to someone, the data sheets for the successor (pin compatible) chip to the SYMBIOS LOGIC 53C825A is here: http://www.lsilogic.com/techlib/techdocs/storage_stand_prod/PCISCSICont/Chip s/825A.BK.pdf LSI Logic bought SYMBIOS several years ago. Also SYMBIOS is the spinoff name of NCR's semiconductor group. So, for example, the NCR 53CF96 which you'll find on the Power Mac 8100 became a SYMBIOS part and then became an LSI Logic part. I suspect that the 53CF96 was licensed and became the MESH chip in later Macs. I haven't had time to do a pinout comparison between the 53CF96 and the MESH, but they're in the same package and on casual inspection the hookups look similar. Anyway, the 53C825 information is available there and LSI Logic claims to have Linux drivers available for download, in case those weren't used when support was added. Jeff Walther P.S. Anyone have a Mac CPU daughter card slot pinout (x500 machines)? I just need about ten pins. I have the rest figured out. I'd be happy to supply my Bandit chip pinout. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
