I use WinNTSetup v3 for install XP, XP.iso already integraed MassStorage drivers with driverpacks. but XP_SETUP shows "The file amdide1.sys could not be found" etc., I must copy C:\$WIN_NT$~LS\I386\*.sy_ to C:\$WIN_NT$~BT\ , then XP_SETUP could be running. Is it a bug? sorry... I integrated massStorage drivers with official XP SP3 again. now, XP_SETUP is running normal. I don't know why, but nothing is nice!
