First, see what will get over-written but I doubt anything that won't be getting wacked soon so no problem... also make a backup of /mnt/gentoo/etc, say /mnt/gentoo/etc2. Then follow on with instructions this also has the nice effect that all will be compiled with a Athlon-xp comipiled GCC... just like as if you did a bootstrap. You won't need to compile a new kernel as you are still using the Gentoo 1.4 CD kernel. Does that work better for you MAL ;-P! Cheers, Jason -- [EMAIL PROTECTED] mailing list

Sounds very similar to a new install... but easier! Requires less personal overhead in getting the system built. bryce -- [EMAIL PROTECTED] mailing list

I was not looking forward to doing "emerge -eD world" on the P3 again, so only doing "emerge -eD system" will be *much* less painful.

I could only think of unpacking a i386 (or i686) stage1 over his system, which should give enough of a base system to boot and compile with. Not guaranteed though. Maybe stage2?

The Athlon XP supports MMX and MMX2 as well as 3DNow and 3DNow2, so that in itself isn't a problem, (assuming this is indeed an Athlon XP... you only state Athlon in your description, but I don't think there is an Athlon 2700+).
