Disabling synchronous negotiation got the CD running again. Obviously a firmware change in the 1540CP didn't go down well with the Toshiba. I didn't have the heart to tell him he probably killed his disk throughput by doing so. :-) This is one of these "find another DOS/Windoze machine to `swap' the CD with" kind of answers. With 6x speed CD's going for $70 it isin't worth attempting to get a new ROM chip for an old CD from the manufacturer. (assuming they even bothered to fix their firmware to begin with) I don't know if the 1540C supports firmware upgrades, if it had flash on it that might be another route. Ted
