Hi everyone;
I installed red hat 9 with VMware. i want to compile a new kernel. i did the steps of compilation and the version of my new kernel is 2.4.20-9. i also did the configuration in the /etc/grup.config for my new kernel. /grub.config looks like:

title Red Hat Linux(2.4.20-8)
root(hd0,0)
kernel /vmlinuz-2.4.20-8 ro root=/dev/sda2
initrd /initrd-2.4.20-8.img

title Red Hat Linux(2.4.20-9)
root(hd0,0)
kernel /bzImage-2.4.20-9 ro root=/dev/sda2
initrd /initrd-2.4.20-9.img

The problem is ,when i try to boot from my new kernel(2.4.20-9) i get the error: "Kernel panic: VFS: Unable to mount root fs on" but if i boot the first kernel no error occurs. What should i write to grup.config as a root path?

Your new kernel or initrd almost certainly is missing the drivers for your filesystem or for the VMware ATA controller. Double check that they are present.

so,lordofdarkness can you tell us how you solved your problem?
