Enable 8g Memory On 2 Opteron System

mem=exactmap mem=640K@0 mem=3071M@1M mem=1024M@4096M

Is this making any sense on boot option?

X64 should see it all with no fancy grub inserts.

Do you have the kernel-bigsmp package installed?

I do not think so. So can I just install it and reboot from it?
On BIOS it shows 4G now, plan to add more to 8G.
But now, the memory checking only shows 3071M.

Oops, I loaded with bigsmp i586, now it wont boot up at all.

Error with
request_module: runaway loop modprobe binfmt-464c

Okay, I can boot it from the original CD in recovery mode.
Mount the HD /dev/sda1 root dir here.

How to go back to my default kernel?

Can I just remove all bigsmp files under /boot dir?
Or how to clean it up bigsmp rpm from the mounted dir?

choose at boot failsafe option, login as root, start yast2 and install the default kernel
btw, cannot understand why you use 586 kernel on 64bit system

First, I used yast2 to find bigsmp, and there is only i586 version.
I thought, it was okay to use it. If not, why yast2 shows that.

After load with bigsmp i586, boot failsafe option was not working.

I ended up using install CD and recovery from checking repository on over 1000 rpms, tooks
almost 1 hour to remove bigsmp rpm.

Lesson learned well here.

The bigsmp kernel is only for 32Bit. The default kernel on 64Bit will see all of your 8GB, no problems.

Well, not in this IBM 6224 Dual Opteron Workstation, memory checking only shows 3071M bytes.
Bios shows 4G. I did some research there is a memory hole setting, but I have no luck to enable it.

If the BIOS cannot detect the 8G, neither will the OS. You have to fix that problem first.
