Just to clarify, Ron, people are talking about EPIA-M here. And the code snippet above is from vt8601/raminit.inc. EPIA-M doesn't use vt8601. EPIA and EPIA-M are two totally different boards (different chipsets, etc). People with EPIA are seemingly OK with my hack to the SDRAM code of 8601. However, EPIA-M users need to tweak the hardcoded magic numbers in the DDR code of vt8623. So, please open a epia-m directory, instead of epia, in the freebios2 tree. -- Takeshi _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
