protected mode stuff wasn't implemented yet...

There's been a series of patch to add ES40 proposed by Tristan Gingold
last March.  Look here:

l%5D_%5BPATCH_0_24%5D:_add_alpha_es40_system_emulation

I haven't had time to continue to work on it. It was able to boot and
run linux and partially boot
tru64.  Both AlphaBios and SRM were ok.

The main issue was speed and IO-TLB (necessary for Tru64 and VMS).

I'm only worrying about Linux at the moment. If the patch series boots Linux,
I'm happy to test it.

Yes, I got a linux shell.

Did you boot Linux with -kernel?

No.

 Do you have the Linux .config you used?  And
what gcc/binutils tuple were you using? (Just straight alpha- unknown-linux?)

Yes.

Tristan.
