 Posted: Thu Sep 27, 2007 5:59 pm Post subject: moving from P4 to centrino with same hdd [SOLVED] |
 |
|
hi there,
I have a question ... my laptop with P4 just died and I've gotten older Centrino laptop from work (IBM T41P). I'm planning on putting hdd from my P4 to Centrino one. What is the best way to follow to migrate? I plan on something like -
- recompile kernel and include correct network adapter module
- solve other peripherals problems
Do I have to recompile whole system & world, or it's fine change make.conf now and apply it only for newly compiled applications? Any suggestions appreciated ;)
I don't have access to my gentoo now, though as far as I remember my make conf had only those -
| Code: |
CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer"
|
thanks & cheers,
mahdi

considering you are really staying inside the same arch (i.e. x86) you shouldn't see very many issues.
yes, verify your chost is ok but even recompiling your kernel may not be necessary, except with laptops where hardway is so specific.
I've moved a single install of gentoo from a celeron to a p4 to another p4. |

Sounds like good plan fo me and I've been moving this system from PII TP600 to few different PIII's and now to this P4 T30.
And if you had P4 and this T41P is P4, what are the "real" differences within 'em (other than chipset & drivers)

Those flags seems fine for me and I think you'll just need to recompile the Kernel and boot 
Check the specs and other things from http://www.thinkwiki.org/wiki/Category:T41p

So Pentium M is also P4 for gcc or is there something else than recommended? I had before ASUS L5800C - http://gentoo-wiki.com/HARDWARE_Asus_L5800C - with Intel Pentium4 2.6GHz and T41 is Pentium M 1.7 |

http://gentoo-wiki.com/Safe_Cflags#Pentium_M.28Centrino.29.2FCeleron_M says
| Code: | CHOST="i686-pc-linux-gnu"
CFLAGS="-march=pentium-m -O2 -pipe -fomit-frame-pointer" |
And cause P-M is newer than P4 & P4M (supports sse2 etc.) it should work with it just fine (but I'm not "really" experienced with it) ,so just stick that HD in to it and try to boot it and if it doesn't work then chroot in to the system with live-cd and recompile the Kernel.
