At one point I had Win2K Server on there, and that could see both processors. (We're migrating to Linux). So I installed Slackware 9.0 (my personal favourite distro), then did some updates. The 2.4.21 kernel was released (thank you) and I went to install. The current kernel 2.4.20 didn't have SMP enabled on that machine but I thought I'd try 2.4.21 with SMP. So I did, using menuconfig I enabled SMP (only one option right?) and then compiled the beast, config lilo and then thought I was good to go. Reboot was fine (after I remembered to include the PCI stuff that I forgot the first compile) but cannot see the 2nd processor. `cat /proc/cpuinfo` (below) only shows one CPU in the machine :[. Did I miss something in the menuconfig? I don't know where to even start troubleshooting this. I suppose I should also mention that I'm using the software raid1 and 5 and booting from the raid1 device (/dev/md0). Please advise. root@mimir:~# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 7 model name : Pentium III (Katmai) stepping : 2 cpu MHz : 498.696 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse bogomips : 996.14 root@mimir:~# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid5] read_ahead 1024 sectors md0 : active raid1 sdb2[1] sda2[0] 8360896 blocks [2/2] [UU] md1 : active raid5 sde1[2] sdd1[1] sdc1[0] 17772288 blocks level 5, 16k chunk, algorithm 0 [3/3] [UUU] unused devices: root@mimir:~# cat /etc/lilo.conf boot = /dev/md0 raid-extra-boot = "/dev/sda,/dev/sdb" prompt # Update this when you get this kernel working # default = Linux_2.4.21 default = Linux_2.4.20 timeout = 60 change-rules reset vga = normal # 2.4.20 image = /boot/vmlinuz root = /dev/md0 label = Linux_2.4.20 read-only # SMP 2.4.21 image = /boot/bzImage.2.4.21 root = /dev/md0 label = Linux_2.4.21 read-only David Busby Systems Engineer busby@pnts.com
