Quad Core Processor

[foleydude1amor]

I have just put a quad core in my computer and Fallout won't run now, I believe I saw a mod out not to long ago to help with this, can someone point it out to me or help me fix the problem another way? Thanks =)

This is a damned good question. I believe what you are referring to is found in the following link:

 

Large Address Aware Enabler for FO3

 

I can download the item, but I'm not confident enough to implement the feature itself for fear of rendering my computer un-bootable. I have lag issues, but not so bad that I would risk my pc.

 

I can understand the instructions up to the most important part. But do I change the original and normal XP Boot.ini:

 

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

 

To:

 

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer /3GB /Userva=2900

 

Or:

 

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /3GB /Userva=2900

 

Or:

 

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /3GB /Userva=2900

 

Please reply using the EXACT SAME FORMAT used here, wrapping the ENTIRE boot.ini in Code Wrap, and only if you actually know what the hell you are talking about. Please add the Vista version as well for those that need it.

 

Also, is it possible to boot in 2 different formats? If so, how?

I have a quad core system, and have never had to do anything special for Fallout 3. But of course my system started out as a quad core and was not upgraded to become one.

 

That said, last time I tried booting Windows (32-bit XP) with the /3GB switch on in boot ini, Fallout lagged like hell for some reason. I quickly took the /3GB switch out and rebooted.

 

I now run 64-bit XP which recognizes all 4GB of my RAM and Fallout 3 works just fine.

 

Also, about your question here:

Also, is it possible to boot in 2 different formats? If so, how?

 

What you would do is something like this: (this is copy/pasted from my boot.ini and slightly edited--my system actually dual-boots 32 and 64bit XP, since I didn't format before installing XP64, I removed references to that) The below would give you a screen to select which one you want, defaulting to /3GB on after 15 seconds. Default appears to go for the first entry in the list that matches the given path. So if you want to default to without the /3GB just put it on bottom.

 

[boot loader]
timeout=15
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional with 3GB" /noexecute=optin /fastdetect /3GB
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

 

You could add whatever other switches you want, as well. I don't recognize the /usepmtimer switch and it was not listed on http://technet.microsoft.com/en-us/sysinte...s/bb963892.aspx so I googled it and got this: http://support.microsoft.com/kb/895980 which only seems to apply if you have an AMD quad core (eg: a phenom) -- which mine is. And yours too apparently.

 

Either way though, Large Address Awareness has little to do with CPU, only RAM.
