New computer with AMD MPX 2200 dual CPU's.

First tried to install install-amd64-universal-2005.1.iso and got the message:
Quote:
Your processor does not support long mode. Install a 32-bit version.
So next tried install-x86-minimal-2005.1.iso and this time got as far as the chroot step. Entered
Code:
chroot /mnt/gentoo /bin/bash
and I am being told
Quote:
Cannot run command '/bin/bash'. Exec format error.
Can anyone help, please?

Is your cpu really 64 bit? What does this say

cat /proc/cpuinfo

You're cpu is definitely NOT 64bit. it's an ordinary athlon-xp with smp capabilities. I guess you were getting those exec errors, cause you tried to chroot into a 64bit-environment...

Of course. My confusion. Thanks for the assistance. I've been working with a 64bit for some time and just spaced. :oops:

May have answered my own question. I'm using a 32 bit live CD, aparently I need to use the 64 bit version to instal a 64 bit tarball. I give it another go tomorow.

This is what cat /proc/cpuinfo gives me

processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 31
model name : AMD Athlon(tm) 64 Processor 3000+
stepping : 0
cpu MHz : 1980.067

There is more but don't really think it is important. I do have a true 64 bit processor and I am getting the same error

error - chroot:cannot run command '/bin/bash' : Exec format error

I am using the stage 3 2005.1 install

Any suggestions?

Thanks

Are you sure you're using a 64bit-install-cd? can you post the output of "uname -a" and the name of the iso image you downloaded?
