OS: SuSE 9.1 System: Compaq Workstation 6000 with dual P-266 and 128MB RAM When I installed 9.1, the second processor was failing so it installed and works fine using Processor 0. This morning I pulled the processor cage and reseated the cards and now Processor 1 works consistently. I used the YaST online update to select the smp kernel but there was an ominous warning not to try to install the SMP kernel as the installation should have installed the correct kernel. (It did but only one processor was working then.) Question: How can I get 9.1 to use the second processor? (Aside: SuSE is dual booted with M$ Windows 2000 Professional which was installed as SMP but apparently reverted to uniprocessor. Now it refuses to boot after detecting the second processor until I restore the SMP image [whatever that is!]. All this makes sense to me - if I were from Redmond!) Thank you, Lucky Leavell

Ignore the warning. Simple as that. You may have a choice of two kernels for smp (you did in prior SuSE's but not sure about 9.1). You want the 4Gig one, AKA non PAE. Its 10 to 20% faster on the hardware you have but it limits main menory to 4gig. BTW: slip 512 meg into that box and it will do everything you want. Dualies are so responsive as desktop machines, and make Very nice servers. I have one (almost same hardware as yours in production for 5 years now).

That question/answer just reminded me that I wanted to ask how you can check that SuSE has installed a kernal capable of using both processors? alan -- http://www.ibgames.net/alan Registered Linux user #6822 http://counter.li.org Winding Down - Weekly Tech Newsletter - subscribe at http://www.ibgames.net/alan/winding/mailing.html

Type top in a shell, then type digit 1 while watching top display. It will break out each processor separately. You can see what percent of time each is used. -- _____________________________________ John Andersen

If you want to find out if you have an SMP kernel how about something as simple as typing this in an xterm or console... uname -a My box responds with this... Linux zeus 2.4.20-4GB #1 Tue Jun 15 09:19:00 UTC 2004 i686 unknown unknown GNU/Linux Yours will have -smp with the kernel version. If you have the SMP kernel installed then it will use both procs. If you have the Uniprocessor kernel installed and want to install the SMP kernel then just stick CD one in and copy it to /tmp and install it. It does require anything else and if you run SuSEconfig afterward then it will update everything all nice and proper. :) - Ben -- "There is no need to teach that stars can fall out of the sky and land on a flat Earth in order to defend religious faith."

Brilliant - I've used top often, but I didn't know that option existed! Thank you alan -- http://www.ibgames.net/alan Registered Linux user #6822 http://counter.li.org Winding Down - Weekly Tech Newsletter - subscribe at http://www.ibgames.net/alan/winding/mailing.html

zcat /proc/config.gz |grep CONFIG_SMP or just rpm -qa kernel-*smp
