2. What has changed...

2.1 ...since version 2.x ?

To say it frankly, almost everything. The underlying concepts are the same,
but the software part has been completly redesigned
to overcome the limitations of previous versions and to make it easier to
use. An highlight of the new features :

     All functions (bpmenu, bpclean, bpunzip) are encompassed in a single
program.
     The program can run not only from the boot rom, but also under DOS,
Windows 95 and Linux.
     The program can now restore images of FAT16, FAT32 and EXT2FS
partitions. If someone want to write NTFS support,
     let me know... For now, NT users still have to stick to FAT16.
     The program can not only restore disk images but also add and patch
individual files in order to customize the client
     behaviour.
     Disk images are not any more bound to 87 MB. They are now file-system
independant archives.
     We provide a mean for automatically downloading a disk image to an
arbitrary big number of clients at the same time
     (broadcast).
     You can now write your own secure boot script, that will determine the
behaviour of the machine before the real boot.
     You can now boot any Linux kernel, without applying any patch. Its is
also possible to provide a command line and a
     ramdisk image.
     You can authenticate users at boot time using a Unix, NT or Radius
server and deny them any access to the machine.
     Full national language support is included.
     And many, many other new features...

Is there a program for converting old archives to the new format ?

     No, because the internal format is radically different. But you can
easily do the conversion by yourself:
       1.Boot an old image (unzip it to your disk)
       2.Remove calls to the old unzipreg utility and replace them by the
adequate patch commands (it is very easy, see
         the detailed instructions below)
       3.Run the new mrzip program to create a new-style disk image

2.2 ...since version 3.0 ?

Version 3.0 was the beta-release. A dozen of sites around the world have
tested it during a month and given much of their time to
help us finding bugs and to suggest enhancements. Thanks to all of them for
their patience, and in particular to Maciek Uhlig, Dick
Velders and Jeff Teeters.

A few minor features have been added since 3.01, such as support for diskless
Linux boot (by disabling the cache).

Version 3.10 introduced compatibility with Intel's Wired for Management 1.1a
NetPC standard. The tools now work with any
PXE-compliant boot ROM (as are most on-board boot ROMs) available today.
Thanks to InCom GmbH for giving us the PXE
bootprom that permitted this developpment. We also succesfully tested the
tools with the PXE Boot ROM that I found incidentally
in my Dell computer with onboard network card (called LanDesk Service
Agent).

Version 3.11 to 3.12 added UNIX server-side tools (a PXE Proxy DHCP server
for Solaris and Linux, and an enhanced TFTP
server for Linux), as well as detailled informations on server-side setup and
the PXE booting process.

Version 3.13 added Advanced Power Management support (PowerOff command).

Version 3.14 added minor enhancements and some corrections. We fixed a
problem with the terminal under RedHat 5.1, and
another problem in the syntax of the "if" command. We added some features
suggested by Manel Rodero :

     A new APM variable let you know if your system support the Advanced
Power Management (i.e it supports the poweroff
     command).
     A "beep" command.
     A new parameter to DrawWindow, to include a title at the window
creation. You can now do DrawWindow 200 200 400
     200 "Title".

Version 3.15 added full VESA support. BpBatch now support several video
modes, to accomodate old computers not being able to
display 800x600 graphics. A new parameter has been added to InitGraph to
specify the video mode, and a list of detected video
mode can be retrieved from the new VESA-Modes variable.

Version 3.16 fixes the following bugs:

     "Malloc failed" during the Fullunzip process of a multiple fragments
image. Many thanks to Christian Meyer for his
     collaboration.
     A bug which prevented the linux version of MrBatch to properly fullunzip
images. This bug was located in the low-level
     functions of MrBatch, so it may fix other problems encountered in the
linux version of MrBatch. Many thanks to Jeff
     Teeters for his collaboration.
     An error in the codepage translation tables. This bug was found by Manel
Rodero. You can find the bug report in the
     BpBatch forum.

但终是能回到中原的。江南有杨柳、桃花，有燕子、金鱼……
汉人中有的是英俊勇武的少年，倜傥潇洒的少年……但这个美
丽的姑娘就像古高昌国人那样固执:

    「那都是很好很好的，可是我偏不喜欢。」
