[gentoo-user] Booting from Install cd

[gentoo-user] Booting from Install cd

[Kyle Vorster]

Hi guys,

I am sorry for such a newbie question but I really wane start learning 
more about linux and use gentoo on my desktop computer.

Now I've burned both pcc and pcc64 to two cd's but when rebooting it 
just boots back into my old system which were Mandriva 2006 with Lilo

Any one got any advice or any thing i can look at.

I have a Intel Computer, 64Bit with two CPU's and Sata drive.

Looking forward to some replies.

Kind Regards,
Kyle Vorster

pcc is ppc?
you should use a correct architecture for you cpu.

Try ia64.

Check your settings in BIOS, booting order.
Check the CD is well burned. Could you try it in other computer?

Yes, if those 2 CPUs Kyle mentioned are Itanium processors - I doubt. I guess 
these are EM64T processors in which case the correct setting is somewhat 
misleading AMD64 . 

In case of EM64T, the system setting can be built upon this setting 
(in /etc/make.conf):

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=nocona -O2 -pipe"
CXXFLAGS="${CFLAGS}"

The NOCONA setting is crucial, as Intel is slightly different from AMD.

Also, look at your /proc/cpuinfo , flags section. Than set appropriate USE 
flags according to this table:

CPU flag   | set this
 present   | USE flag
-----------+---------
mmx        | mmx
sse        | sse
sse2       | sse2
pni        | sse3 *
mmxext     | mmxext
3dnowext **| 3dnowext
3dnow    **| 3dnow

*  No ebuild seems to use sse3 flag (yet)
** Well, 3dnow is for AMD/AMD64, put here just for reference
