I installed red hat 9 in vmware workstation, and want to update the kernel from 2.4.20-8 to 2.6.15.5.
When I run make install, problems come as follows:

No module mptbase found for kernel 2.6.15.5
mkinitrd failed
make[1]: *** [install] Error 1
make: *** [install] Error 2

Then I take off the refferences
mpt***
mpt***
in modules.conf and modprobe.conf

but another question comes

sh /usr/src/linux-2.6.15.5/arch/i386/boot/install.sh 2.6.15.5 arch/i386/boot/bzImage System.map "/boot"
grubby fatal error: unable to find a suitable template

I take care of the question for a whole day,boring me so much.
Help me!

Why did you install red hat 9? it is ancient, obsolete, unsupported and its hardly any wonder that a bleeding edge kernel won't install properly on it.

You really should get a current distro, like Centos 5.x or Fedora 8 or 9.
