You mean kernel compiled without SMP options? I tried only with dual CPU.
It is not working with 8GB.

This has only 2 options, AUTO and Manual. If I select Manual, I have to 
adjust 4GB memory hole size, which
has 64mb, 128mb, 256mb, 512mb, 1gb options. What should I choose?

I will try above configurations and let you know.

It is IBM, RAM is 4x2GB DDR PC2700. I tried IBM diagnostic tools to test 
memory,
but somehow it didn't finish. I will try memtest.
