So add it. ;) The latest specs say to use fixed timeouts, ignoring CSD values. So the latest code (which I'll repost when git-mmc merges) got rid of the bogus MINI timeout, and uses those timeouts unconditionally. There seems to be no downside to using slightly longer timeouts than a given older-spec card would tolerate. - Dave ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
