900 * The structure below defines the content and organization of the system

902 * SDATA.ASM. Ring 0, read/write access is obtained by the clock device
903 * driver using the DevHlp GetDOSVar function. (GetDOSVar returns a ring 0,
904 * read-only selector to all other requestors.)
906 * In order to prevent an errant process from destroying the infoseg, two
907 * identical global infosegs are maintained. One is in the tiled shared
908 * arena and is accessible in user mode (and therefore can potentially be
909 * overwritten from ring 2), and the other is in the system arena and is
910 * accessible only in kernel mode. All kernel code (except the clock driver)
911 * is responsible for updating BOTH copies of the infoseg. The copy kept
912 * in the system arena is addressable as DOSGROUP:SISData, and the copy
913 * in the shared arena is addressable via a system arena alias. 16:16 and
914 * 0:32 pointers to the alias are stored in _Sis2.
