Generally that shouldn't be necessary. Intel's and AMD's x86_64 |
7 |
technologies, also known as amd64 because AMD designed them, are |
8 |
compatible. |

Before plugging your hard disk into your new mainboard, though, you |
10 |
should make sure that your kernel supports enough of that board's |
11 |
integrated devices to be able to boot. IOW, you will most probably |
12 |
need to change your kernel config and compile a new kernel. Or you |
13 |
could just try it and hope for the best -- but have some bootable CD |
14 |
or thumbdrive ready so that you can boot from that and chroot into |
15 |
your installation if necessary. |

The same as you should have right now: |
20 |
CHOST="x86_64-pc-linux-gnu" |
21 |
CFLAGS="-O2 -march=native -pipe" |
