I should I guess have mentioned that this is a multi-boot system. grub is 
installed on my Debian partition and has been handling my 6 OSs fine. I 
have even had NetBSD on an extended partition alongside my Linuxes and it 
has booted fine (I think I read this was not possible) with the following 
grub entry:

rootnoverify (hd0,9,a)
kernel --type=netbsd /netbsd
chainloader +1

... but now that I have updated to 4.0, I get the following when I 
attempt to boot NetBSD:

Error 13: Invalid or unsupported executable format

I am wondering what I should change the parameters to to get this to boot. 
I can play around on the grub command line some, but any advice would be 
welcome :^), other wise I'm just kinda blindly casting about.

I tried removing the chainloader +1 line as I read it was no longer 
necessary, but this didn't have any effect. I suspect it is the "kernel 
..." line but am not sure what to alter this to.

Thanks in advance for any ideas ...
