## 4.2.1. Tunable parameters

To reasonably run XFree86 you may have to adjust a few system parameters.

On LynxOS 2.5.0 include a line

      #define X_WINDOWS

in `/sys/lynx.os/uparam.h`.

For earlier versions you'll have to edit `/usr/include/param.h`:

      Tunable                                           Old     New
      USR_NFDS      number of open files per process     20      64
      NPROC         number of tasks                      50     150
      NFILES        number of open files in system      100     250
      NINODES       number of incore inodes             (same value as NFILES)
      QUANTUM       clock ticks until preemption         64      20
      CACHEBLKS     number of cache memory blocks       202      >= 4096

The new values are those suggested by the LynxOS documentation for their X Window package.
