It all seems to be working as of now Help can be reached via /? Error found in help file, wpi should be run as %wpi%wpi.bat since %wpi% has to have a "\" at the end of it anyways. Also default wpi path is %cdrom%\$OEM$\WPI [AutoRunParams] installdir=%cdrom%\$oem$\Install\ wpidir=%cdrom%\$OEM$\WPI\ title="Swimming_Bird's WPI XP Install Disk" wpi=1 ;by default: ;installdir=%cdrom%\$oem$\Install ;wpidir=%cdrom%\$OEM$\WPI ;title="WPI Windows XP Install" ;wpi=1 (runs %wpi%\wpi.htm) ;%wpi%=wpidir Download Future versions will be more fool proof, no need to worry about "\" and some other things. Error, currently has issue running batch files, will be fixed in next version.
