<center><h3>Elf/OS</h3></center>
<p>This is my project to create a disk based operating system for Elf class
computers.  I am designing this OS initially for the hardware that I already
have for my real Elf.

      Final slash no longer needed on CHDIR and RMDIR<br>
      Final slash does not cause invalid directories on MKDIR<br>

        Changed the boot sequence to remove the AutoBaud feature, this
        makes the kernel easier to use when using BIOSIO.  If BIOSIO is
        not being used, then the serial AutoBaud will be still be
        executed<br>
        The Elf/OS installer is still serial only, but I do plan on releasing
        a BIOSIO version of the installer soon

        terminal devices.<br>
        O_TYPE, O_MSG, O_READKEY, O_INPUT have been added (these currently call
        F_TYPE, F_MSG, F_READKEY, F_INPUT from BIOS)<br>
        Kernel now attempts to execute /INIT during boot process.  This can be
        any Elf/OS executable program, but must return properly to Elf/OS at
        conclusion.  Initially this can be used to initialize other I/O devices
        or other system specific devices.  I will be writing a full INIT prgram
        that can read a startup script for running multiple programs at startup.

Biosio is a bios module that simplifies the usage of various terminal systems
used on Elf Computers.  This module provides a uniform I/O interface to three
different video systems: 1861/port 7 keyboard (Elf II), 6847/port 5 keyboard
(Super Elf), and Serial (Q, EF4).  Programs written to use this module will
be capable of running on any of these 3 video systems.<p>
