Ok, now I got my first hand experience with LongHorn as I installed into VMware. Speaking of the Installation Media, I'm pretty please with the new folder structure. FOLDERS: BOOT - wich contain setupldr.bin and bootfix.bin and fs_ext.sys (?) - that's all DOCS - one of the first folder to delete! contains a sample unattended.xml + 2 .htm information files - that's all SOURCE - contains 54 files, the biggest one is install.win (692Mo) SUPPORT - similar to Windows XP cd... with deploy.cab and others (to be deleted too) VALUEADD - second folder to delete! FILES AT ROOT: autorun.inf readme.htm setup.exe win51 win51ip winbom.ini - Oh! new stuff from WinPE So I like this new disposition. Really clean! I have created a unattended.txt file with the tool provided in deploy.cab but I was Expecting XML!!! It created a "regular" answer file not something similar to the example provided in the DOCS folder. Anyone got more info about the winbom.ini, unattended (XML or regular) and where we should put those files along with the $OEM$ folder (if exist in LongHorn)
