Hello,

i would like to allocate more than 2 GB of memory on an IA32 architecture.

The machine is a dual XEON_DP with 3 GB of Ram and 4 GB of swap space.

I have tried with the default SUSE 8.1 kernel as well as with a
2.4.20-pre4aa1 Kernel compile by my own using these Options:

CONFIG_HIGHMEM4G=y
CONFIG_HIGHMEM=y
CONFIG_1GB=y

but I am only able to allocate 2 GB with a single malloc call.
I tought it should be possible to allocate up to 2.9 GB of memory to a
process, with this kernel settings.

Thank You for any help

Hartmut Manz
