Many thanks for responding, guys. After reading the AMD64 FAQ and |
| 19 |
its links, this is my plan: |
| 20 |
|
| 21 |
1. I'll copy my athlon-xp x86 system to the new box, build the |
| 22 |
kernel to get support for the new stuff and re-jig the make.conf |
| 23 |
so: |
| 24 |
|
| 25 |
CFLAGS="-march=athlon-xp -msse2 -02 -pipe -ftracer -fomit-frame-pointer" |
| 26 |
MAKEOPTS="-j3" |
| 27 |
|
| 28 |
2. Then I'll do an amd64 install on a separate partition - I |
| 29 |
multi-boot anyway. This way I can see what's best for me. |
