Hi,

1. cd /stand/build
2. create the kernal parameter system file /usr/lbin/sysadm/system_prep -s system
3. make your changes to the system file
vi system
4. build the new kernal
/usr/sbin/mk_kernel -s ./system
5. back up the old kernel and sys files
mv /stan/system /stand/system.prev
mv /stand/vmunix /stand/vmunix.prev
6. install the new kernel
cp /stand/build/system /stand
cp /stand/build/vmunix_test /stand/vmunix
7. reboot system
8. verify the kernel changes using sysdef

HTH,
Devender

Hi,

If you want to boot it from vmunix.prev then at PDC prompt give
bo pri
Select Y when prompts for interacting with IPL.

Now at IPL give
hpux vmunix.prev
Moreover you can also see the files in /stand from here itself by
hpux ls (Or ls -l)

HTH,
