Here is an attempt to translate the prompt and help text into something
which is legible and, as a bonus, correct.

The /dev/mem file by default only allows userspace access to PCI
12
-
space and the BIOS code and data regions. This is sufficient for
13
-
dosemu and X and all common users of /dev/mem. With this config
14
-
option, you allow userspace access to all of memory, including
15
-
kernel and userspace memory. Accidental access to this is
16
-
obviously disasterous, but specific access can be used by people
17
-
debugging the kernel.
