Aha...the $15 processor you don't want to be considered "wasted". I did
similar trying to get $5 ISA ATI video board working on an old Compaq 486
with Mandrake Linux 5.3/6.1. I spent over 15 hours trying to get 1024x768
video to work (which it could do with Windows 9x). Found that something
about XFree86 support for the ATI card doesn't let you use it's full
features (accelerated) if you have more than 16MB RAM in the machine. <16MB
RAM with Linux and Xwindows = useless. I have that $5 ISA ATI video board if
anyone would like a deal on it. ;)
But back to the dual processor compilation thing. Heres what I did to make
my dual processors work for an Ultra 2 (mind you it's a different processor,
but the technique may work for you).
* I loaded the 'stock' .config file from the SuSE sources
(supposedly, /boot/vmlinuz.config and /boot/vmlinuz_24.config point
to the stock config files for 2.2.xx and 2.4.xx kernels of the sources you
installed, if you installed your sources from SuSE source packages)
* Compiled the 'stock' kernel (that should get the same as what you're
running now)
* Installed it and tested that the machine booted identically. (Compared
dmesg outputs before & after, as well as system logs)
* Went back into kernel config and ONLY turned on the SMP kernel option
* Recompiled and installed.
* See if it boots and runs with both processors. top and ps will show
you which processors are running each process. There are other methods of
dumping this but I don't know them right now.
Once you get that far successfully, you can tinker a little at a time
(removing IDE support for us purists), to add/remove options that you
desire. Saving your config file as a different name each time helps keep
things in stages.
Worked for me. Your mileage may vary.
