===== Using 3 Gigs of Memory in JAS =====


You must modify your boot.ini file to allow JAS to use 3 gigabytes of memory. The boot.ini file is the root directory of your C drive, i.e., C:\boot.ini. Windows Explorer may be set to hide boot.ini and other hidden (system) files. To change this setting, which may require admin privileges, click Tools, then Folder Options, and select the View tab. Under Hidden Files and Folders, select the Show Hidden Files and Folders button. \\ 

A boot.ini file for an XP Home version of Windows might look like this:

<code>
[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 Home Edition" /noexecute=optin /fastdetect

</code>

Follow these directions:

  * Backup your current boot.ini file.
  * Edit your boot.ini file.
  * Referring to this [[http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx |page]], modify the line that starts with multi and add **/3GB** to the end of the line, so that it looks something like this:

<code>

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /noexecute=optin /fastdetect /3GB

</code>
  * Save the changes to boot.ini.
  * Reboot your computer.
