Simple way to install XP without CD (AHCI must be disabled!).
1 create a bootable USB-stick with DOS on it.
2 copy the i386 directory onto your USB-stick.
3 start DOS on the USB stick and format the harddisk of the drive with format c: /s (makes it a FAT32 partition and bootable)
If not, then run fdisk first and delete all partitions on the harddisk and create a new one, then reboot and retry the previous line)
4 copy the i386 partition to the harddisk: <md c:\i386> <copy \i386 c:\i386> (between <> are the commands needed)
5 reboot the machine and let it boot the harddisk (remove USB stick!).
6 <cd i386> <winnt.exe> (I thought it was that one, there are a few exes in it)
7 after installation and drivers, goto command-prompt in XP, <convert c: /fs:ntfs> to make the drive NTFS.
Voila, you are set and installed XP without a CDrom.
