Here's mine. I also use grub only.
title Vector Linux 6.0
root (hd0,5)
kernel (hd0,5)/boot/vmlinuz-2.6.27.29 root=/dev/hda6 vga=791 splash=silent ro
initrd (hd0,5)/boot/initrd
boot
where hd0=master HD and 5=partition
Important Note: Linux starts counting from 0 not 1. So if vector is on the 6th partition, it will be read as 5.
For what it's worth, after a lot of tinkering and head scratching, here's what worked for me:
title Vector Linux 6.0
root (hd0,4)
kernel /boot/vmlinuz-2.6.27.12 root=/dev/hdc5 vga=791 splash=silent ro
initrd /boot/initrd
boot
Thanks for the help!!
