what is menu.lst equivalent for lucid

[Tapas Mishra]

Hi,
I am doing some experiment with pv-ops Dom0 kernel with Xen as mentioned here
http://wiki.xensource.com/xenwiki/XenParavirtOps
so I have basically compiled a few kernels which are many in number.
I remember long time back using menu.lst for grub menu.
Before I go to boot my system I searched for menu.lst file but I could
not find it any where.
I am using lucid 64 bit.
Can any one suggest me what should I be doing.I would prefer to do
manually than update-grub sort of thing.
