Changes from version 21.4.3 to 21.4.4 (10-Jun-2000) John Coffman

  Map Installer
  -------------
    - Added a minor RAID patch from Richard Bollinger: 'lilo-21_4_3.also'
      http://www.elliott-turbo.com/lilo/
    - Expand COMPACT/LINEAR warning message to include COMPACT/LBA32

  Boot Loader
  -----------
    - LARGE_EBDA option now loads second stage loader at 800:0000, and
      position of command line is changed; makes room for 512K kernels
      to be loaded low.
    - Minor optimizations when ES is reloaded (PUSH/POP) vs (mov thru AX)
    - Serial line now turns on DTR/RTS at initialization
    - Minor bugfix in numeric conversion (k/K-suffix)

  DISK.COM utility
  ----------------
    - The disk.com utility no longer requires 'nasm' to assemble.  The
      source code now makes the diagnostic floppy with "make floppy".


Changes from version 21.4.2 to 21.4.3 (06-May-2000) John Coffman

  Map Installer
  -------------
    - Added RAID patches from 'lilo.raid1.also' from Richard Bollinger
      http://www.elliott-turbo.com/lilo/lilo.raid1.also


Changes from version 21-3 to 21.4.2 (12-Apr-2000) -- John Coffman

  Boot loader
  -----------
    - bugfix in 'read.S' that disabled the combination 'linear' with
      'compact' ( '-l' and '-c' together).
    - fixed numeric convesions; kernel accepts octal, decimal, and hex, so 
      octal is now recognized by the boot loader.
    - bugfix patch where ES segment prefix was ommitted (RHL 'second.patch')
    - bugfix for compilation with 'LARGE_EBDA' option which caused command
      line passed to the kernel to be truncated at 78 characters
    
  Map installer
  -------------
    - RHL6.2 loopdev updates added
      
      
Changes from version 21 to 21-3 (24-FEB-2000)  -- John Coffman 
-----------------------------                  <johninsd@san.rr.com>

  Boot loader
  -----------
  
    - will boot from disks up to 2048Gb in size, as long as the BIOS allows
      the Enhanced BIOS calls for 32-bit sector addressing using packet calls.
    - checks if BIOS supports packet calls (int 0x13, AH=0x42), and uses
      these calls if 'lba32' was specified.  Otherwise, it uses
      the C:H:S addressing scheme of the original IBM-PC BIOS.
    - the disk read routine is separated into its own source file, "read.S",
      which is included in the first-stage, and second-stage loader codes.
      The first stage loader uses a very stripped down read routine, since it
      only deals in single sector transfers.
    - if BIOS does not support 32-bit packet calls, and the cylinder address
      overflows when the 32-bit address is converted to C:H:S, then a "9f"
      error code is issued.

  Map installer
  -------------
  
    - added the '-L' command line switch and 'lba32' configuration file 
      global option.  
    - map compaction of 'lba32' addresses is supported with the existing
      '-c' switch (or 'compact' configuration file global option).
    - floppy disks now will always fall back to C:H:S addressing.
    - changed the -v option to now accept a single digit to set the verbosity
      level; e.g., 'lilo -v 5 ...' replaces 'lilo -v -v -v -v -v ...'
      for maximum diagnostic output.
    - LILO version information is moved to the file 'version.h', and VERSION
      is now deleted.  This allows for tracking of VERSION_MAJOR (=21) and
      VERSION_MINOR (=3) for this and future code paths.
      
  BIOS tester
  -----------
  
    - Inspired by 'dparam.com', a much more extensive BIOS test program is
      included with this version.  Called 'disk.com', it was developed 
      under DOS, and requires 'nasm' to be assembled.
    - DISK.COM will probe the BIOS for disks supported by the BIOS, and report
      on their CHS geometry.  If EDD is supported, the EDD geometry is also
      reported.  If disks with cylinder numbers of 1024 or above are detected,
      it will issue a recommendation to use LILO with the 'lba32' option.
    - Creation of the bootable floppy image version of this utility is in-
      complete at this time.
      
    
Changes from version 20 to 21 (5-DEC-1998)
-----------------------------

  Boot loader
  -----------

    - cylinder calculation could overflow when using LINEAR (fix by Jonas
      Aaberg and an anonymous contributor)
    - first-stage loader code begins with the byte 0xFA (a CLI instruction).
      This works around the "INACCESSIBLE_BOOT_DEVICE" blue screen bug of
      Windows NT 4 (reported by too many people to mention)
    - new build-time option LARGE_EBDA to load boot loader in the 0x8xxxx area
      instead of the 0x9xxxx area (disabled by default; problem reported by
      Josef Moellers)

  Map installer
  -------------

    - new build-time option USE_TMPDIR to honor TMPDIR when creating temporary
      devices (disabled by default)
    - now only 0x1b6 bytes of the boot sector are overwritten, which preserves
      the passwords DR DOS stores there (fixed by Roy Millar)
    - -u and -U accidently implied -v
    - "BIOS drive 0xNN may not be accessible" warning was printed in cases
       where the drive code was never used (fixed by Andries Brouwer)
    - change rule for DOS16_big incorrectly used DOS16_small_hidden when
      hiding (fixed by Anthony Richardson)
    - RESET in CHANGE-RULES did not remove default rules (fixed by Kurt
      Garloff)
    - added support for Mylex DAC960 PCI RAID controllers (by Leonard Zubkoff)
    - added support for third to sixth IDE interface
    - build-time option READONLY was not used properly
    - fixed a few harmless compiler warnings

  Documentation and installation
  ------------------------------

    - user's guide claimed that partitions are hidden by setting the highest
      bit in the type (i.e. 0x80). The correct value is 0x10, which is also
      what is used in the code.
    - removed useless (and potentially harmful) DEFAULT_PATH from
      keytab-lilo.pl (fixed by Andries Brouwer)
    - consistency of build-time options is now checked before build starts
    - QuickInst has now limited knowledge of multi-disk configurations
    - doc/Makefile: added targets user.ps and tech.ps
    - user's guide still claimed that kernels can't be larger than 512 kB
      (reported by Jean-Albert Ferrez)
    - weird description of the purpose of option BEEP (reported by Tom Toffoli)

  -----------

    - now supports 19200 bps and 38400 bps on the serial line (UNTESTED)
    - when reaching the end of the command line buffer, input is ignored
      instead of being treated like [Enter] (by Martin Mares)
    - fixed numerous bugs in patching of heap end pointer in setup.S (by Martin
      Mares)
    - images can now optionally be launched with a single keystroke (no [Enter]
      required)

      RESET, TYPE, NORMAL, and HIDDEN
    - OTHER sections have new configuration option CHANGE plus sub-options
      PARTITION, SET, ACTIVATE, and DEACTIVATE
    - OTHER sections have new configuration option MAP-DRIVE with sub-option TO
    - now only 0x1b8 bytes of the boot sector are overwritten, which preserves
      some magic numbers NT stores there
    - compiles with 2.1 kernels (asm/boot.h problem - reported by many people)
    - should also compile under 0.93 or such again (required NORMAL_VGA etc.,
      which didn't exist back then)
    - lilo -q  now prints unknown VGA modes also in hex (by Martin Mares)
    - option SINGLE-KEY to allow single-key activation
    - -Wno-parentheses  is no longer needed

    - removed some ancient dead code
    - new option KEYTABLE to specify non-standard keyboard mappings
    - PS/2 ESDI disk (/dev/eda and /dev/edb) support (by Andrew Kroll)
    - geometry.c:last_dev now only probes for the first two IDE disks
    - because chain.b is used for everything anyway, specifying the chain
      loader when booting from a driver other than the first one is no longer
      mandatory

  Documentation and installation
  ------------------------------

    - changed all references to nic.funet.fi to ftp.funet.fi

      for the one being booted) are hidden, just like OS/2 BM does (build-time
      option HIDE_DOS)

      the current image
    - added REWRITE-TABLE option to patch partition table at boot time
