The board I'm testing on has an Intel strata chip and is not responding to the query. If I use 0xFF, then everything is fine. AMD chips seems to be happy with either command (I think because the AMD automatically returns to read mode after a command anyway). It looks like this was changed with the jedec-probe additions so maybe this is necessary for older jedec chips (which I haven't tested). Alice
