Unix Kernel Switching?
How do I go about switching from one Kernel to another?

I figure the process is somewhat like "compile -> remove old boot reference -> add new boot reference -> reboot/restart kernel"... but honestly I have no idea how to do this...

I'm trying to test out a piece of software, but it only runs on a previous kernel... I never thought there would be problems... but I figure it would be easier to temporarily install/point to a different kernel, then figure out the bug... especially given that the software never installs onto a system with the newest kernel anyway.

any help?

Hello, i am not sure about doing it on UNIX but i can give you how to...on Redhat Linux! see if that helps you?

=> open /etc/grub.conf and change the default field to the available kernel you want to.

Doing it on UNIX must be something similar!

BTW:You should restart the system after editing /etc/grub.conf
