Would there be memdisk or a similar program/methode to emulate a cdrom and boot from a iso file available for efi boot in the future. I need this, because the *stupid* installer check from which medium the system was booted and if it's not cd than it fail. Thanks and regards Michael

I would hazard a guess that the installer is also bios specific and is going to need to be tailored for EFI boot anyway. -- Matt Fleming, Intel Open Source Technology Center

It's a DVD based installer where I try to change this to be installable via network. The DVD are masterpreloads from a Notebook company. I think you know which :-) We have a lot of this notebook to install so it's easier to do this via network (also different models/types). OK, now the problem: You are right, the old versions of the installer (XP and Win7) run under BIOS. The new (Win8) require EFI boot. I test it with BIOS boot, but the preload install script from this company check if the boot is EFI or legancy. If it's not EFI it stop with the info that the boot methode must be EFI. Next I tried to boot via some windows pxe methodes and wimboot to only need some boot files and the wim image. But when I do it this way the installer fail with the info that the system must be booted from CD/DVD. I tried to change the installer and also found the registry key with the boot info, but the installer perform a wpeutil which set the registry back to 'ramdisk' when I not boot from CD or stored iso image in memdisk. It's very frustrating Thanks and regards Michael Gesendet mit AquaMail f?r Android http://www.aqua-mail.com

Specifically it would have to become an EFI device driver rather than a BIOS device driver. Certainly plenty to do for someone who is interested. -hpa
