    WRONG!

      If you are using XENIX, your keystrokes are NOT going through
      any ROM routines - in fact, the ROMs are ONLY used at boot time
      to determine HARD DISK parameters.

      The Xenix device drivers are totally seperate from any of the
      ROM BIOS routines!

      (this info relates to MicroSoft/IBM Xenix 2.0 (SVR2ish) only)
