By removing ntdetect.com from my /tftpboot folder I get the following ERR:
Setup is inspecting your computer's hardware configuration....
This means that the setupldr.0 - 'h' can't find ntdetect.com in your /tftpboot folder.
Probably a faulty HEX edit or file version.
Can you send me your h,startrom.0,ntdetect.com files?
