    Default /proc/cpuinfo - displays 1 of 2

    EDIT: Fix Found!! See post #2.
    I searched and found threads related to pyrit and GPU cores, but I think this is new. My system has dual AMD uProc's but a quick check of /proc/cpuinfo shows just one. Note that 'model name' field indicates dual cores:
    Code:
    root@pwnsauce-desktop:/usr/include/linux# cat /proc/cpuinfo
    processor       : 0
    vendor_id       : AuthenticAMD
    cpu family      : 15
    model           : 35
    model name      : AMD Athlon(tm) 64 X2 Dual Core Processor 4400+
    stepping        : 2
    cpu MHz         : 2210.560

    clflush size    : 64
    power management: ts fid vid ttp
    
    root@pwnsauce-desktop:/usr/include/linux#
    Funny thing, when I purchased the system, I booted the BT4b LiveCD and verified both uProc's were present!

    Any help? Thanks in advance.

    Found a fix. Including the link for future reference:
    [all variants] DualCore becomes SingleCore after upgrade 8.04 to 8.10 [Archive] - Ubuntu Forums

    To summarize, it came down to modifying the /boot/grub/menu.lst file.
    As root, edit this file and page down until you see this section:
    Code:
    ## ## End Default Options ##
    
    splashimage=6cf4ede5-bfac-4383-9e35-4b259f6018cc/boot/grub/splash.xpm.gz

    kernel          /boot/vmlinuz-2.6.29.4 root=UUID=6cf4ede5-bfac-4383-9e35-4b259f6018cc ro quiet splash
    initrd          /boot/initrd.img-2.6.29.4
    quiet

    kernel          /boot/memtest86+.bin
    quiet
    
    ### END DEBIAN AUTOMAGIC KERNELS LIST
    Now change a single line, as shown here:
    Code:
    ## ## End Default Options ##
    
    splashimage=6cf4ede5-bfac-4383-9e35-4b259f6018cc/boot/grub/splash.xpm.gz

    ## Here is the line to edit. Scroll to the right to see changes.
    kernel          /boot/vmlinuz-2.6.29.4 root=UUID=6cf4ede5-bfac-4383-9e35-4b259f6018cc ro quiet splash acpi=off noacpi apic=off noapic

    Reboot your BT4pf machine, and you should see both AMD cores in /proc/cpuinfo:
