Well it took some time, but I haven't given up: TOSHIBA CD-ROM XM-5701TA 0557 is a firmware rev that has *working* audio control. I found out by borrowing a Digital RRD46 which is a XM5701 in disguise. It contains the RRD46 firmware, but also the XM-5701TA 0557 firmware. Jumper selectable by the parity jumper (parity is for our firmware always enabled, the jumper is 'borrowed' so the hardware can remain as-is). I'm not sure if there are two completely seperate firmware revs, or only some settings/mode pages are changed. I suspect it is the latter. The firmware itself lives in a socketed SMD PROM. As far as getting in touch with a contact in Toshiba I did not have as much luck. Is there anybody on the list that has the right contact within Toshiba to get the music loving XM-5701TA owners a working firmware? It is at least proven by now that Toshiba has the technology ;-) Wilko _ ______________________________________________________________________ | / o / / _ Bulte email: wilko @ yedi.iaf.nl http://www.tcja.nl/~wilko |/|/ / / /( (_) Arnhem, The Netherlands - Do, or do not.
