Hey there, I'm not sure if this is the proper place but hopefully I can get some help.

I'm trying to use the 3GB Enabler and it tells me I need to edit my Boot.ini file. Looking around (I have Windows 7) and I find that I don't have one, but its called bootmgr instead. Can anyone tell me how to do this using Windows 7?

I've done the following *Strikes* so far.

1) Make Fallout 3 'large address aware using this utility.

a) make a back up copy of 'Fallout 3.exe'.
put Fallout3.exe in the utility folder
c) double click 'START.BAT'
d) follow the instruction in the command window
e) once made 'large Address aware', return the fallout3.exe to your game folder.


2) Enable the /3GB switch on your computer. The switch is entered in the system’s boot.ini file and takes effect after a computer restart. Here's how to do it:


....WARNING: From MADBORIS himself;

"I only suggest this for people that are intermediate to advanced users, so if you don't feel comfortable editing a boot.ini, you may not want to proceed. Editing a boot.ini improperly may render your PC unbootable, which is why I suggest you copy/paste the entry in the boot.ini to make a new additional boot option, leaving the original intact."

OK, disclaimer over, what next!?


***For Windows XP***


Right-click My Computer and select Properties. The System Properties dialog box will appear.

a) Click the Advanced tab.

In the Startup and Recovery area, click Settings. The Startup and Recovery dialog box will appear.

c) In the System startup area, click Edit. This will open the Windows boot.ini file in Notepad.

d) In the [Operating Systems] section, add the following switches to the end of the startup line that includes the /fastdetect switch: " /3GB /Userva=2900" (do not include the quotes)

e) Save the changes and close Notepad.

f) Click 'OK' two times to close the open dialog boxes, and then restart the computer for the change to take effect.

***To turn off the 3GB switch***

Remove: "/3GB /Userva=2900" from the startup line.
