Maybe, but in real use it will be limited by memory and IO speed. And current 32bit systems have already 64bit data bus. So you will not get +100% but less. I cannot guess, did you make some benchmark?

They would probably ask you what you did for idea linux on desktop to be more real and when you'll answer that nothing they will be wondering why do you mentoring them...

I think that most very old games are not problem to emulate under dosbox but some newer are atill hard to emulate smoothly, even on c2d @3,5GHz. Real power like ~ PIII would be needed.

I was talking with friend (coreboot coder) and he didn't know anything about intel core issue. They are more targeting on AMD because AMD gives them _complette_ specs (intel requires NDA for some low level things). Even he say that AMD has about 5 people who are coding for coreboot and they commited on SVN about 160000 lines of code. So there must be some intention of AMD. I quess they will replace BIOS with coreboot on future mobos. On other hand intel doesn't like coreboot and strictly pushes EFI. So it seems that DOS future depends on AMD and coreboot + seabios...

I think it is for year 2011, maybe for 2004 would be ok. As I said I downloaded it free (for non-commercial use) from lineo, it might be in 2001-2002....

It's a good new there's working 64bit port of DOSEMU :) I didn't hope they will do it. Pure realmode progs are usually older and doesn't need full power but it's fine that 32bit pmode progs runs fine - i think there are still some calls for 16bit functions from 32bit DJGPP programs but probably not so often that would cause big slowdown. So when it is possible for DOSEMU why not for NTVDM...
