- The /dev/mem file by default only allows userspace access to PCI
- space and the BIOS code and data regions. This is sufficient for
- dosemu and X and all common users of /dev/mem. With this config
- option, you allow userspace access to all of memory, including
- kernel and userspace memory. Accidental access to this is
- obviously disasterous, but specific access can be used by people
- debugging the kernel.
