And SSE, too. Only add 3dnow (after install the athlon) (Normaly the athlon xp should work with all the p3 binarys) Set CFLAGS="-mcpu=i686 -O3 -pipe" install the drive on your P3. emerge -eD system (base system and compiler need to be on a "save" level) Change to Athlon. CFLAGS="-mcpu=athlon-xp -O3 -pipe" and add 3dnow to USE-Flags emerge -eD world mfg Stefan Hildebrandt -- [EMAIL PROTECTED] mailing list
