I very much doubt MP3 playing is going to work without an FPU. The 2300SX specifications are badly mangled by the website but appear to suggest that it needs 5V@3A - this is not especially low power and you should be able to find alternatives. Check out www.pcengines.ch and www.ewayco.com [I haven't used either of these manufacturers but have found them in searches]. >Alternatively, porting MATH_EMULATE back from NetBSD etc might be an=20 >option, but might be a larger task, and apparently NetBSD math emulation= =20 >did not work out of box either (seems to be a cpu detection bug, based on= =20 >mailing list discussions). FreeBSD used to support both MATH_EMULATE and GPL_MATH_EMULATE. Support was removed in July 2003 but the bits are still in the CVS repository. I don't know how much effort would be involved in resurrecting it. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --jousvV0MzM2p6OtC Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQFHkySJ/opHv/APuIcRArKyAJ0fVtw7txLsYBkYhTdu3LKIOoSpTQCeJnng PwJwE4uAXuhkqzjMSwYd85s= =G8oq -----END PGP SIGNATURE----- --jousvV0MzM2p6OtC--
