I'm a fool and I managed to accidentally move the kernel into the trash... I am now obviously unable to boot. grub bootloader obviously gives: 'error 15: file not found'
I found the following link below to offer good guidance, but I don't have any internet access.

What I have:
small old cluster using Rocks 2.6.18 (CentOS)
GNU GRUB 0.97

previous kernel and location:
/boot/xen.gz-2.6.18-164.6.1.el5

I wondered if I could edit the boot commands to direct grub to the kernel in the trash but I couldn't seem to get that to work (not sure how to get to trash... perhaps this idea is stupid).
"kernel ~/.local/share/Trash/xen.gz-2.6 ... "

Any suggestions would be greatly appreciated. Otherwise I'll have to find a way to get internet access and start over.
