Re: Any ideas why we can't even boot a i386 ?

I believe i386 compatible code was disabled in the kernel because it was
hindering the performance of more advanced Intel based architectures.

Supposedly you can build it back in but that would either require building a release
yourself or finding someone who already built the i386 version.

Might be nice to have two x86 ISO versions for releases in that case so people don't feel
screwed :).

Is there anybody out there who can try to run a straight -current

Ie, not a i486, not a Cyrix, not an AMD but a genuine Intel i386DX
(SX would be but too suicidal to be informative).

Yup. 386dx - 33Mhz. Results below:

BTX halted

hmmm .. you think it doesn't like my hardware?

        I could try installing something previous (like 4.7) and cvsupping
if you are interested.

        Please let me know - I'm game for this and it is a pleasant break
from wrangling world weary sun3s back into some semblance of service.

Thankyou.
