Hello, I have an ibm thinkpad 600x and I need to do bios upgrade in order to run Linux or windows xp on it but I cannot do it because the battery is dead. Would somebody like to help me by using 1Byte Hack method with this file http://www-307.ibm.com/pc/support/site. ... FYS2U.html What I mean can somebody apply that method and send to me the modified file so that I can just write it on floppy or cd? I have read about that method here http://forum.thinkpads.com/viewtopic.php?p=94632
This is my e-mail: livram79@gmail.com
Thank you very much!

Success! I did it my self. Hjanzen's instructions were very helpful:

Code: Select all

OK, here we go: 
On the update floppy disk you find a.o. the file updtflsh.exe 
Open that file in a hexeditor, scroll down about 7/8 of the text till you see at the far right column the following 3 lines: 

pdtrom /np /prep 
2 updtrom upd 
trom updtrom /np 

On the left you have 16 colomns of figures. 
The far most left figure in the line "2 updtrom upd" is 32. 
That figure represents the figure 2 in the above text. 
Now select that figure 2, and replace it by a 1. 
On the far left, 32 has become 31 now. 
That is all!!
