Hi !
Great news - since 4 hours I've no girlfriend, but maybe an _SMP_kernel_ !
That's better than nothing !

I have the SCSI-chip, and i always tried to turn it on and off in BIOS - but
this made no difference concerning the boot from the latest SMP-kernel.

Jupp. Some days ago it was possible to boot off the IDE ... but now - no chance.
This is why i wanted to start to take a look into the autoconf.c, somewhere where
the while(1){} of the init is, there was the function calling isa_configure() or so.
This was the point when i considered to ask you :-)

Okay, I can go on, but the problem is that i have 16 GA586DX but only a sinlge
SCSI disk ..... but I would really _DIE_ for having a FreeBSD-SMP. At the moment,
my boss wants WinNT and is keen on any reason for switching off of Unix.

This could take some time.... i've to get a null-modem, an old pc but the worst
thing is that i've never done kernel debugging with a debugger/FreeBSD right now...
just straight device-drivers. You still want me to copy the boot-up-sequence ?
But could take some time.
