> This program is public domain !
You are allowed to use and copy it, but only the author is allowed to
gain any profit.
There are a lot of virus available for the Amiga (just take a look at
VirusX !!!). They have nearly almost one aim : the bootblock !!! Mosttimes
you just can use INSTALL to kill them. But some programs (like LICENCE TO
KILL, ARCHON, INTERNATIONAL SOCCER) use their own boot block - There
are lost if a virus writes itself on the boot block. But you can a repair
your disk - all you need is to save the bootblock as file and in
an emergency case youjust copy the saved bootblock back on the disk !
the program
-----------
First you get a list of some (important) vectors :
the numbers at the top should be 0 - it means no program will survive a
reset. The numbers at the bottom should begin "$00f" - This means the
vectors used the write on disk have not been changed.
In other cases use VirusX by Steve Tibbet (V3.2 FISH 216 ) to check if
there's really a virus !
Use EXIT to leave the progam , press ABOUT if you wanna to know who's
the author (it's me).
You can see four rectangles - for each drive (df0:, df1:, df2: , df3:)
one rectangle ! In the middle of the rectangles you can find the
information about the boot block the disk in the drive:
DF0: / DF1: / DF2: / DF3: : Name of boot block, ??????
(name of the drive) means that it's an unknow
bootblock
Status : what happened when Bootblock
Champion tried to get the
boot block
CSum (shot for CheckSum) : OK mean that the checksum is
all right, BAD means that the
checksum isn't all right.
If the disk is no AMIGA dos disk
nothing will appear (no AMIGA disk ->
No AMIGA dos checksum !)
Type : DOS means it's an AMIGA dos disk.
KICK means it's an AMIGA 1000 Kick-
start disk. Another message means
it is no AMIGA disk.
Beacause AMIGA is a multitaking computer, it can happen that for example
VirusX installs a disk but Bootblock Champion III still says it's not
installed ! So press U key to update the information.
Each boot block has five gadgets :
LOAD : writes a file back to disk
Use same option you've saved the bootblock (execpt executable
file they cannot be written on the disk)
SAVE : saved a bootblock as file
There are three ways of saving a boot block :
whole bootblock : The whole boot block is saved. Use
this option if you want to archived
the boot block.
bootblock code : Only the code of the boot block is
saved.
Use this option if you wanna analyse
the program of the boot block.
executable file : This code of the boot block is saved
as executable file which can be run
from CLI (on your own risk)
But not every boot block will run
from CLI - BootIntro-NG will run from
CLI !
SHOW : take a look at the boot block
There are four pages ($000, $100, $200, $300). Press P key
once to print the pages. Press OK to exit.
COMAPRE : compare the bootblock to a saved bootblock - it allows you
to identify a old virus with a changed message.
Red means the byte is identical, white means the bytes are
not identical. Press CANCEL to exit.
INSTALL : like CLI Install
It writes the original bootblock code on the bootblock.
Information for users with only one drive
------------------------------------------
SAVE and COMPARE : remove the disk after the function has opened its
window . BootBlock Champion III will keep the boot block .
LOAD : change the disk after BootBlock Champion III tells you
to insert the new disk.
How to archive a boot block
-----------------------------
1. Check if it's a special boot block.
If it's the original boot block code , you do not need to save it
because you just have to press INSTALL to rewrite the boot block.
If it's a virus, kill it !!!
2. Save it as whole bootblock
If you want to rewrite it, just load whole bootblock.
IMPORTANT :
Some virus protectors and the ByteBandits virus don't let BootBlock
ChampionIII write a boot block on the disk - In this case you will
get a VERIFY ERROR !
The drawer BootBlocks contains some bootblocks found on varrious PD disks.
> IF YOU ARE MAD YOU CAN DESTROY A GAME USING BOOTBLOCK CHAMPION III. SO
YOU USE THIS PROGRAM ON YOUR OWN RISK !!! BOOTBLOCK CHAMPION III WASN'T
MADE TO COLLECT VIRUS AND TO SPREAD THEM !!!!
Changes between V3.0 and V3.1:
· df2: and df3: can be used if df1: doesn't exist
· df3: can now be used
· the code of the executable file will now be forced to use chip mem
