You've gotten some good advice about the steps necessary, but not the advice that you'll spend a lot less time if you do a new install from scratch. There have been massive changes since 4.9 (released 10/29/2003), including: heavy rework of the kernel and networking stack to work properly on SMP; inclusion of power management; a total rewrite of the wireless subsystem; a large number of new drivers; rework of the sound system; an entirely new USB system; extensive rework of the ports infrastructure; many thousands of new ports; replacement of the default UFS1 by UFS2; two reworks of the ata architecture; the devd system; several different revisions of the compiler; and, well, really, thousands of other changes. Unless you have local changes to your source, you're going to have a great deal less heartbreak just to start from scratch. mcl
