As for the 36-bit address extension, I haven't tried it but the following .config entries look relevant:
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set

I don't really know what it does, but judging from the help entry, it appears like it can still only address 4GB at a time, so it's more or lessActually it's a lie. I've got a dual Pent III with 4Gb RAM. You cannot have a single process that uses more than 2Gb of RAM with any of the Linux 2.4 kernels. We hadda install Solaris on the box to do what we wanted to.
