Re: [SLE] Problem with recognizing 4 GB of RAM SOLVED



Hi Prakash,

Do you mean, if this option is enabled, in some systems running SuSE Pro
9.3, system might crash? I am experiencing some system freezes at my site,
and I am not sure whether these options are enabled or not. And I am not
able to find out any reasons why this happens and they happen at random.

Yes. If memory hole remapping is enabled, then from what I have read, certain
kernels will not work in a stable manner. My experience is quite limited.
In my experience SUSE 9.3 would not even install on a system with memory hole
remapping enabled, whereaas SUSE 10.0 did.

If you would be kind enough to explain a little more, it might help me take
a look at the system BIOS options.

On my sustem, when you enter the BIOS setup there are a number of options.
The third one down on the left is

Advanced Chipset Procedures.

When you enter that screen, you hare given a number of other selections.
These include CPU frequency. DRAM Configuration, CPU Spread Spectrum, SATA
Spread Spectrum, etc.

Then enter the DRAM Configuration screen. There will be anotehr set of
options related to Timing Mode, memclock Index, CAS# latency and the like.
One of those options should relate to "memory hole remapping" That option
may not be there. As I indicated in my original post, the Epox updated
BIOS, has an entry for software memory hole remapping and another for
hardware memory hole remapping. The updated BIOS for the ECS KN1 Extreme
motherboard does not have any entry for memory hole remapping.

I hope that clarifies things.

Mike
