btw, nice sig morfius

You guys can always check out what was said about DeepFreeze in the Product Reviews forum. With that said...

DeepFreeze is pretty good. What you're describing is that they installed it wrong. If you set it up right in the first place, it's pretty good at it's job. In other words, the administrator must have edited msdos.sys to DISABLE the booting-to-safemode or booting to DOS, and they must also enact a bios password and disable booting from a floppy or CD-rom.

I'm afraid you only got past it because they goofed.

The way Deep Freeze works (as far as I have tested and experienced (in a cyber cafe))

Deepfreeze makes a mem resident copy of the File Allocation Table,
you are allowed to write 2 the disk, it is just never allocated to the FAT,
next reboot, the files r turned into garbage (same as deleting, no link in FAT = no file)

So you could find out what someone installed last boot

I agree with Terr, DeepFreeze is one hella good program, if used correctly..

And you guys seriously belive that admins on norwegian schools can handle anything else than MS word correctly?

Chances are some of us will need to install Deep freeze some were along the line so its important that we know weather 10 year olds can just edit ini files or if it takes a little knowledge to get past. So if what the_Jinx said you should just be able to back up the fat table and restore it next time you boot up. Of course this would most likely fail if other people are moving files around or installing software.

There are a bunch of free programs that can back up fat tables. Norton Utilities can to if you have it.

Of course there’s always the uber l337 way of doing things.

The following was blatantly ripped of from (the complete PC upgrade and maintenance guide) <= it’s a book; you know the things made from paper.

How to back up your master boot record using DEBUG

1.
DEBUG_MBR.DAT
You will see a file not found message because the files didn’t exist before. Don’t worry about the message.

2.
A
This tells debug that you want to assemble something.

3.
MOV_DX,9000
This command tells debug to move the value of segment 9000 to the register DX. Since you can’t write anything to a register, you have to move this information to and extra segment.

4.
MOV_EX,DX
This command moves any information in register DX to the extra segment (called ES).

5.
XOR_BX,BX
BX is the offset; Xor is a programming trick to set it to zero.

6.
MOVE_CX,0001
This command stores the value of track 0 and sector 1 in register CX.

7.
MOVE_DX,0080
Here, you’re storing the information at head 0 of drive 80(you’re hard drive, a: is 01)

8.
MOVE_AX,0201
This command tells debug to read 1 sector

9.
INT_13
This is the bios disk call

10.
INT_20
This tells the bios “I’m done!”

11.
Press enter

12.
G
Runs the program. When its dome you should see a message that says program terminated normally.

13.
R_CX
This command ask debug to show you the value of register CX and lets you edit it.

14.
200
This is the size of the files that debug will write


15.
W_9000:00

16.
TYPE Q TO EXIT DEBUG.

Now its time to restore

1.
DEBUG_MBR.DAT
This time if you get a file not found message stop and exit debug (type q)

2.
L_9000:0
to direct debug to load the information to 9000:0

3.
A
Lets debug know you want to assemble a files

4.
MOVE_DX,9000

5.
MOVE_ES,DX

6.
XOR_BX,BX

7.
MOV_CX,0001

8.
MOVE_DX,0080

9.
MOV_AX,0301
This command tells debug that you want to write 1 sector

10.
INT_13

11.
INT_20

12.
press enter to stop entering commands

13. G runs the program

14. Q to exit debug.

Ok one time it tried this it worked the other time my computer got royally f**ked.

lol.. Well as far as being a skript kiddie because your trying to defeat your school admin... Well I don't think that applys. I mean.. How many of YOU did the same thing while you were in school. Heh.. I know I did.. and i guess that helped me know what I know about computers today.. (not to mention changeing my english grade) lol

[|337]

changing grades is kinda lame.. isn't it?

[xmaddness]

not when it determines if you pass or fail.. I always have to look out for number one. And I only did it once.

[|337]

So becouse you're better with comps than the school admins you cant fail a class?

[xmaddness]

At the that particular moment.. yup...
