[CentOS] Inquiry:Problem installing application on Cent OS

Dear All
Please be informed that I tried to install the "Real VMX" application on my
Cent OS client . I setup the environment variables and build kernel . Then I
add the following entry to my /boot/grub/menu.lst :
title Real VMX
     rootnoverify (hd0,0)
     kernel -type=netbsd /vmx
I tried to reboot my Cent OS client and at the boot loader when I select
"Real VMX" I got the following error :
"Error 1 : File name must be either an absolute pathname or blocklist"
Can you please do me favor and let me know how can I overcome ?
Let me thank you in advance
