    Remember pre WinME when you could define a RAM disk to cache web pages to? Well, MS removed real-mode support in ME so the ramdrive.sys driver was no longer supported. I just found a replacement for win2000/xp. If you search for ramdisk at download.microsoft.com it comes back with no results but it is there at


    That is a direct link to the file. I tried removing some of the specific page specifiers to get to the parent page and I got "you are not authorized ...." The download is a self-extracting executable. After extraction see the ramdisk.htm for install instructions. The configuration must be done in the registry directly. The key is at:


    You can specify the drive letter to use ( default is Z: ) as well as the size ( default is 1MB ). The size is specified in high order word of the hex value ( I used 0x00F00000 which should be 16MB but Windows reports the disk size at 14.9MB -- if anyone knows why I'd appreciate a reply. )

    You have to reboot after the initial installation. If you set the Internet Explorer settings to use this drive as the cache location you have to reboot again after that at which point Windows moves all the files from C: to the ramdisk (whatever drive letter you specify in the registry). After this second reboot, my automatic logon to XP had been disabled but I just had to go into the control userpasswords2 and re-do it and it works just fine again.

    I've been curious about using ramdisk for running a software development environment. When running the software, it's particularly slow, and is really disk intensive when it compiles.

    After I install ramdisk, I thought there might be a way to get XP Home to keep an image of the ramdisk on the HDD. That way, when it boots, it reads the image and restores the ramdisk. And, when I shut it down, it saves the ramdisk image back to the HDD. So, when I run the program, I start it and run it from the ram disk.

    I realize if the confuser crashes, I lose whatever is on the ramdisk, but at least when I restart, the image from the last good shut down is available for me to start over with.

    I think I can figure out how to make it load ramdisk from a saved image when it starts, but how do I get xp to write the ramdisk contents back to the HDD during shutdown?
