RH 7.1 non-selection of bigmem kernel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have 2 custom distributions.  One is based on RH 7.1 with errata kernel
2.4.18-24.7.x.  The other is based on RH 8.0 with kernel 2.4.18-26.8.0.

I have an IBM x345 with 8GB memory and a Xeon Processor with multithreading
enabled.  The RH 7.1 installs the uniprocessor kernel, but the RH 8.0
installs the bigmem kernel (as it should).

Does anyone know what would make the difference?  Is there anything in the
RH 7.1 distribution I could upgrade to get it to install the bigmem kernel
itself?  I could do it as a post installation step, but would rather not.

Also, when I only had 4GB memory in the box, 7.1 still did the UP kernel,
but 8.0 did the SMP kernel (due to multithreaded CPU).  Same basic question,
can I make the 7.1 distribution automatically recognize and install the smp
kernel in this case?

The apps the installs are supporting aren't ready for RH 8.0 yet, and my
need to support 8GB may arrive before they're ready.
