installing 32-bit on AMD64?
 
Hi. I was trying to install an LFS build but ran into problems so I decided to take a break from that and give another try at installing Gentoo.

My question is:

I have AMD64
Code:

CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                1
On-line CPU(s) list:  0
Thread(s) per core:    1
Core(s) per socket:    1
Socket(s):            1
Vendor ID:            AuthenticAMD
CPU family:            15
Model:                12
Stepping:              0
CPU MHz:              1994.110
BogoMIPS:              3988.22
L1d cache:            64K
L1i cache:            64K
L2 cache:              512K

I don't have the RAM required for a full 64-bit system so I'm wanting to install 32-bit. When I go to the mirrors to download the stage3 tar ball, which one do I need?

I am using the Gentoo 12.1 Live DVD http://mirrors.us.kernel.org/gentoo/...2ul-2012.1.iso to install with and I booted the x86 kernel.

I'm looking at the handbook for the AMD64 but should I be looking at the one from x86?

I'm trying to get this done before I loose access to the internet for awhile. As to when this could happen depends on my ISP.

????. How much do you think you need (above a 32-bit install) ?

To save confusing yourself, use the x86_everything - including the handbook if you really feel you have to go 32-bit.

There's no such thing as a minimum RAM requirement to run a 64-bit system...

I've just always been told that to run a true (full) 64-bit that I need to have at least 4Gigs RAM. I on the other hand only have 1Gig RAM. I would love to upgrade the amount but the RAM for my system can no longer be bought and finding used has come up empty.:o

My (old) quad-core ran fine when I reduced the RAM to 512 Meg (for some testing).

Go 64-bit; a Gig will it run fine, certainly no worse than the 32-bit.

This actually has raised another question that is related to this.

I found this doing a search: 32Bit Chroot Guide for Gentoo/AMD64
This is where I am currently

7.d. Alternative: Using genkernelI'm not able to find where 32Bit Chroot Guide for Gentoo/AMD64 comes in. :confused:
