I might not quite get your question. You want to add your IDE drive
to the grub boot menu on sda?

Type `dmesg|grep hd' and find out the letter of that IDE drive. hda
looks like your cdrom, so lets pretend the drive is hdb.

Then change your device map, say now it looks like:

$ cat /boot/grub/device.map
(hd0) /dev/sda

So change it to read

(hd0) /dev/sda
(hd1) /dev/hdb

Then edit /boot/grub/menu.lst and after the line:
   ### END DEBIAN AUTOMAGIC KERNELS LIST

Add your grub entry for that ide drive:

title Debian GNU/Linux, kernel 2.6.18-3-k7
root (hd1,1) #This assumes the boot partition is the first
partition. hd1,2 would assume the second
kernel /vmlinuz-2.6.18-3-k7 root=/dev/hdb1 ro quiet splash
initrd /initrd.img-2.6.18-3-k7
savedefault

Of course the kernel/initrd lines will have to be changed to reflect
the kernel you have installed. You can mount the boot partition on
hdb to find out if you're not sure.
