I forgot about the imgburn.ini option. I found this, seems to be what you were referring to. ISOBUILD_DontPromptOSInstallationSettings=1 Will give it a shot tomorrow. Thanks for the reply.

Summary: Is there a command line switch or setting in the .ibb that bypasses the OS Detection? Or maybe just a silent "deny making changes" option when propmted by it? I have a little script that lets me drag and drop a user info file, uses the settings in it to make some changes in the XPSource folder, then runs IMGBurn silently to burn the disc. I've been using version 2.4.6 (going from memory, that may not be accurate) and everything was working perfectly. Recently re-setup that machine and upgraded to IMGBurn 2.5.0. It seems the new version's OS Detection wants an XP Disc to be ISO9660 Only, where the old version wanted it to be ISO9660+Joliet.(which is what I need it to be) My issue is that because I've got extra files/links/etc in the $OEM$ folder, the ISO9660's all caps makes the resulting install rather ugly. ISO9660+Joliet results in a valid output disc, and I can click NO to the OS Detection popup in the new version and get a perfect disc using that setting. But I'm trying to get rid of the popup, so that things stay drag and drop automated. I've looked through the readme and the menu options, and I've tried searching the forum. Haven't found anything. I am positive the original XP discs don't use all caps, though I'm not sure if they are using +Joiliet or just the relaxed ascii character option.
