What I did, I commented out the whole line and ran it that way. I also tried other settings too. It didn't list much but all of it was video related stuff regardless of the setting. I didn't see anything that should affect booting or even logging into KDE itself. I may not be able to watch videos but I should have a bootable OS and a working GUI as well it would seem. Or am I missing something? It sounds right. > >> My only question left, will those flags affect the kernel image itself? >> I may just have to make sure my USB stick works. > > No. The kernel configuration is completely separate from anything in > make.conf.

Things like ffmpeg and mplayer may not work but that can be fixed after the new CPU is installed. I'll have the correct flags from the CPU itself at that point. Plus it will compile faster anyway. ;-) This is starting to sound good. All this upgrading and the hardest part is going to be the hardware itself. Yeppie!! Still can't believe LVM is going to be that easy. I found a howto someone sent me and read it too. It still sounds to easy. Something has to go wrong here. Lightening coming out the hard drive or something. ROFL I have Grant's email on standby. He included a list of commands. :-) One last question for anyone who has done this recently. When finished, I'll have a FX-8350 CPU with 8 cores at 4.0/4.2GHz, 32GBs of memory all on a Gigabyte 970 series mobo. Would there be any point in upgrading to a whole new rig or is what I have about as fast is reasonable to build? I don't do gaming or anything. Even the GTX 650 video card is likely overkill for what I do here. The older 200 series card is working just fine. On one hand, my current build is several years old. On the other, computers seem to have reached their peak. I'm sure there is more powerful systems out there but would I be any better off with one? Thanks to all for the help on this. Dale :-) :-)
