Is there any side effects of changing the address splitting? What should i change for 2G/2G splitting? should i shift the kernel start?
Thanks

Is there a way to increase the lowmem value for ppc. The MAX_LOW_MEM is defined as max 768 MB. But a value around 1.5 G works with no problem. But when i try to increase this value to 1520 or more, kernel complaints about no space for memory allocation when loading kernel modules. I do not want to use HIGHMEM config. What is the max lowmem value for a ppc system? What other setting are needed to use 1520 MB (or more) as lowmem .
The ppc card has 2G on board memory. 2.4.22 kernel is used.

Thanks

With 32-bit arch you may not use more than 1GB to map the memory (minus some space for some kernel operation). The value of 768MB was not there by chance.

Only an additional comment: I meant with the address splitting 3G/1G. To map more than 1GB, you have to change the splitting 2G/2G for example.
