Kernel

We'll need to configure an SMP kernel to get full functionality of our systems.

  • We need to add SMP support so we can use all 4 CPUs.
  • We need to add large memory (4 GB) support.
  • We need to remove ACPI support, and add APM support.
  • Remove USB and sound, as this system does not have them.
  • Remove SymBIOS SCSI drivers, as we've got nothing attached to that controller. (We're using the ida driver for the SmartArray 4200 RAID controller.)

Initial test on Bud

Downloaded and installed on Bud:

kernel-headers-2.4.27-2
kernel-image-2.4.27-2-686-smp

Package installation updated GRUB, .. next step is to try and boot the SMP kernel.

TEST SUCCESSFUL! On reboot, /proc/cpuinfo shows four CPU processes!

NOTE: These machines (like many Compaqs) MUST HAVE A KEYBOARD ACTIVE DURING BOOT! For the second reboot test, the keyboard was disconnected - and the BOOT PROCESS DID NOT COMPLETE! No messages were logged, even though the boot was in process when the keyboard was removed.

Replicate to Budlight

Repeated process for Budlight, success!

Both machines now running smp kernel, with four CPU processes.
