configuring kernel, booting to root partition


I compiled a new kernel so that I could install drivers for my 2 video nvidia cards
when I select the new kernel off of grub it starts booting and has a kernel panic,
VFS says that is cant mount the root drive
it's trying to mount (0.0) when it should be mounting (0.1)
...so my question is , how do I configure it to mount the right drive?
with gatitude

kernel (hd0,5)/boot/vmlinuz root=/dev/hda6 vga=0x317 splash=silent desktop hdc=ide-scsi hdclun=0 showopts
initrd (hd0,5)/boot/initrd


(hd0,5) is the partition where the /boot folder is. This also happens to be the root filesystem.

If you have a paritition that has the kernel in it then it would be like this..

kernel (hd0,5)/vmlinuz


Here is the root filesystem..
root=/dev/hda6

This is where the root filesystem is. They are not always nor do they need to be in the same place as this one is.


another example..

kernel (hd0,0)/vmlinuz

this is the first partition on the primary master being used as a boot partition.


root=/dev/hdb2

this is the second partition on the primary slave where the filesystem is.


kernel (hd0,0)/vmlinuz root=/dev/hdb2


In this case the fstab my have this...

/dev/hda1 /boot ext3 defaults 0 0


so that's your /boot partition where the kernel is, the root filesystem is in /dev/hdb2





For yours if the kerel is in /dev/hda1 and the filesystem is /dev/hda2...


kernel (hd0,0)/vmlinuz root=/dev/hda2



If you have it correct then maybe you did not add your filesystem support to the kernel.
