3GB Switch for WinXp x32bit for Civ4 ROM (how to do it tutorial)

Regarding Step 5:
My BOOT.ini file is a bit different than yours. Its because im running a chinese Windows XP pro, which comes with a 'ghost' backup utility automatically installed that apparently changes a few things. I'm still doing the switch as we speak, but ill post my .ini, and we'll see if it works or not in a bit. Or hopefully someone with a very in depth knowledge might know how to do this correctly.

EDIT: Well, the computer started back up, thats a good thing!
I think it should be working- only one way to find out!

Btw, whats the /usepmtimer handle at the end of my ini do?

Well if ur computer started up without a problem then it should work, post here if u have any problems :)

Im not sure what /usepmtimer is actually, maybe someone who knows more about this could say...

os79 @ Yes, thank you for pointing this out, i wouldnt have noticed that it became sticky :D
If I set this as a perment option (remove the original line), will that cause hassles with other programs, or will it all be fine?

You mean having the boot.ini file like this :

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /noexecute=optin /fastdetect /3GB

instead of this :

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /noexecute=optin /fastdetect /3GB

If yes then you won't be having the possibility to select witch version of the windows you want to use during your computer startup process and it will all be fine so no reason to worry about.
Just an additional note. If you're using certain laptops (dell, lenovo, maybe a few others), simply enabling the /3gb switch will result in LOTS of video driver errors.

Instead try adding /3gb /userva=2900
I don't know if my problem is related to this memory switch, but from the day I'm using the 3 gb of memory, when I leave my computer for a couple of hours (it doesn't matter if my computer is turned off, in sleep mode or if everything is unplugged) my monitor crashes, power light flashes and I can hear strange high pitched sound from behind of my monitor, (normally when monitor gets no signal, light goes yellow from green) but it's flashing green light, and my screen is black, I can't even turn off my monitor, I have to unplug it. I have to leave my computer on and wait for a couple of hours (about 3), and then monitor works.

I've got LCD acer monitor.
Monitor issues are always completely unrelated to computers. I could smash your computer with a baseball bat and your monitor would still work fine.
How can you tell if your XP system is 32 bit or 64? This seems like a fantastic trick but Im not familiar with this comp
XP Pro x64 Edition, says so on the start up screen. Requires at least a Dual Core CPU. Been out since 2005. I don't believe it's that rare, easily found at New Egg, Tiger Direct, and other computer distributors. And of course directly from Microsoft. Was 1st developed for the 1st line of Dual Core servers, then added more business apps. Was/is a viable alternative to Vista x64 with XP speed and user friendly processes (less restrictive for admin use and security).

XP Home is 32 bit, as is standard XP Pro.

This may be a stupid question, but does this little tweak make all other games use 3GB ram instead of 2?
Hi there,

Tried apllying the 3GB switch, the file look exactly like the example you've given. But I have an lov graphics setting in my XP now, only 640x480x4bit. I'm not able to change it back to my original 1024x768x32bit, when I do I get an error from file LockMon.exe, that the program made an exeption that couldn't be applied/ran. I've read the microsoft thread for higher end graphics card, but since I only run a integrated g33/g31 intel card - I wouldn't really consider that high-end.. :)

Does anyone have any solutions to my problem?
note; I'm new to this kind of editing
