The model is "Proliant 2500 - E24" (dual PPro). I use the latest "Compaq SmartStart" to configure the HW. Currently, I'm using release 5.10.
The E-Smith/SME installs have always correctly found and utilized both CPU's automatically, and defaulting to boot the SMP kernel. The only issue has been the memory detection, which is due to the Compaq BIOS.
