It's about whether the TLB is like that of the R4k. Actually it's always been a mystery for me why the common code cannot be used for the SB1, but perhaps there is something specific that I could only discover in that "SB-1 Core User Manual" that I yet have to see, sigh... Of course if your TLB is indeed different from that of the R4k, then you shouldn't be setting cp0.config.mt to 1 in the first place... Maciej
