Machines 1 and 2 both failed at SSE2 MISSING.
I created a boot CD-ROM for my third machine and it booted fine. I didn't test everything on the command line, but it got there and all servers were ok. This is on an Intel Extreme 3.20 GHz.

Oh.. thanks
Not what I had expected. Darn. I think I was too enthusiastic about the feature set. I mean, SSE + SSE2 isn't that serious. Sorry about that.
Anyway, I'm playing with the kernel again and re-organizing stuff. Hopefully the problem will go away after I've cleaned up all the code.
Thanks again.

No sweat!
I thought it was interesting that stack on one machine was there and not on the other one. I am assuming that the addressing scheme is virtualized, since those addresses don't really exist on those machines (BIOS mapping excepted). I should have some time this weekend to play with it on the one machine that it works on and checkout the MPEG stuff. I'll also try to get the CD-ROM image to work...perhaps it is a download issue (TEXT versus BINARY).
As for the SSE2, you can probably use SSE for AMD and SSE2 for Intel (at least on the earlier versions of AMD, I've heard that SSE2 will be in Hammer I don't know for sure).

my qemu from cvs gets to 'event horizon' then goes black and hangs.

thanks df. Sounds like no event occurs :-/ Which means the CMOS clock never updates during something like:
save time;
while( time now < saved_time + 1 secs ) loop.
save time;
while( time now < saved_time + 3 secs ) loop.
count instructions executed / 3 secs -> real cpu speed.
I'll improve everything.
I've decided to go all the way and I'm reviewing large parts of the kernel. It is a mixture of code from a few days old to a few years old.
I've learnt a lot in the last few years. This will be good.

how's the going with the development & reorganizing?

Hectic actually. And, I've had no time to do it and I want it done now
I reckon it will probably be finished in a week. It just feels wrong that the kernel is in a non-functional state at the moment. Learning a lot though... always good.

I understand... Often, when I smash some piece of my kernel in shingles to reorganize it, it needs quite some days to get all the side effects of the one single change sorted out. (f. ex. the redoing of the whole file system service in order to incorporate a spanky new vfs layer - about two months I needed.
Well, you know how the hare runs - work draws your attention on it for mosta part of the day and then you 're too tired to do good pace. And that's sometimes really frustrating.
