Alternatively, if you have a CPU with support for 64 bit addressing (any AMD CPU with AMD64 or Intel with EMT64 support), you can install the 64 bit amd64 kernel. This should work on almost any new desktop CPU.

@Gullit

Make sure that CONFIG_NOHIGHMEM is not set.

Set either CONFIG_HIGHMEM4G or CONFIG_HIGHMEM64G to yes, using whichever one is appropriate for the RAM in your system. If you have Note that you should use the 4 gigabyte parameter for less than 4 gigabytes of RAM, and the 64 gigabyte parameter for 4 or more gigabytes (4 gigabytes of RAM, remember is actually slightly more than that).

Set CONFIG_HIGHMEM to yes.

Optionally, set CONFIG_DEBUG_HIGHMEM to yes if you want to log error messages. Since many generic kernels turn this option off, you can probably do without it, especially if you do not delete other kernels from your boot manager’s menu, so that you can still start your computer if your newly compiled kernel is unusable.

Hey, nice post, but you should to explain what’s that option in the kernel to change the memory support!
I know, but I think there are a lot of Debian’s admin that don’t.
