Hi, the manual is currently at 124 pages, not counting future updates. The current version of WRPtool is the .950 upgrade to the .906 base system. To find out more information, please check out the
WRPtool home page and the corresponding forums. The manual is included in the installation package.
As for the requirements, most of the users use it on XP of course, however iirc, it should be okay on 2k as well. While some users have not experienced any significant issues on 9x/Me, repeated reports of a whole variety of bizarre memory errors on those platforms is the reason for WRPtool not being supported on that platform.
