If what you call Triton 2 is HX, then HX doesn't support SDRAM.

Yes, I don't understand why they keep this stupid limit (except for marketing reasons that is). -- Ollivier ROBERT -=- FreeBSD: There are no limits -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 3.0-CURRENT #18: Sun Jun 8 15:32:28 CEST 1997
