Hi,
I don't want to spread FUD but give a little warning. Our dear giant M$
decided that they need extra protection for their OS (maybe because they
still cannot reach security level runtime like other OSes) so they want to
utilize new UEFI feature - secure boot. If this feature is enabled it means
that your PC will not boot any other OS/bootloader without valid
certificate. Keys will be stored in UEFI image and probably only for Win8
and maybe some profi Linux distros. M$ enforce OEMs that they must enable
this feature if they want to use designed for Win8 sticker - a lot of
comming HW.
Of course UEFI secure boot could be disabled but it depends on OEMs if they
include such option in SETUP! I'm afraid that it may happen on some
notebooks/netbooks/tablets they will omit such option (not mandatory) and
secure boot will be permanently enabled so than you will be bricked with
Win8 on such device until someone will hack it... So be careful what you're
buying...

Anyway I think DOS doomsday (on new HW) is comming within few years when UEFI drops BIOS services compatability module. Alternative is to get HW which is supported by Coreboot/SeaBIOS or rewrite DOS such way it will not use BIOS but UEFI API and will emulate BIOS services for DOS apps. AFAIK UEFI runs in all in PMODE.

DOS gives me freedom to unlimited HW access.
