This is a Beta test version of X00.SYS. It is readily available by file requesting it from 1:265/1. If you find any problems with this Beta version, please let me know by direct mail at 1:265/1. Please include a reasonable description of the problem that you are having, as well a description of the computer (including speed) that you are using. Also, give me the exact DEVICE=X00.SYS statement that you have in your CONFIG.SYS file. If you want the latest non Beta version of X00.SYS then you need to request it by version number. For example, X00120.ZIP. If you do not know the latest version number, then a request of X00*.* will get you the latest latest official release and the latest Beta version (if a beta exists). BE SURE TO READ THE TEXT FILES WHATSNEW.??? AND HISTORY.DOC. The documentation may not be the greatest in the world but I do spend a lot of time creating it. I find that often I must repeat the same information in messages to users that is already in the documentation. After a few years, this gets a little upseting. Ray Gwinn
