Can't this be changed, you know, by hacking the registry or something ?!

- hapless 18y agoThere's a boot-time argument that will move the barrier to 3G instead of 2G.
- jcl 18y agoNo. The Windows and Linux kernels are hardwired to reserve a huge chunk of virtual addresses for kernel memory space. Windows can be toggled between reserving 2Gb and 1Gb (the latter of which Linux does by default). I assume this is so that a system memory address can be identified by testing a couple bits, and the minimum size is presumably limited by the chunk of addresses eaten up by memory-mapped devices like video cards.
