multiboot

[Onkar]

Hi,
       I am working on some projects for Linux as well as freeBSD OS. I have
two Hard drives on my system .
(1) 150 GBytes - containing GNU/Linux
(2) 80 GBytes - containing FreeBSD

I Installed GNU/Linux on the first HDD ( full disk ) , and then, FreeBSD 7.0
on second disk . The problem is that I am not able to detect the FreeBSD ???
Please help me ...

regards,
Onkar
