hello experts
I have rh9.0. I have been trying to install my modem driver but each time it says that it doesn't support smp kernel. I have a 2.4.20.xx smp kernel. I tried reconfiguring the kernel but it didn't work. What can I do so that I am able to install the modem driver.
please help.

I assume that the modem driver you have is for one of the winmodems. If that's the case you'd have to be able to get a driver built for an SMP kernel in order to get it to work on a multi-processor system. From what I've seen of winmodem drivers the vendors don't release the source so you can't built it yourself and are at the mercy of the vendor w/respect to an SMP driver. Personally, I'd just get a good "real modem" and hook it up to a serial port and skip all the winmodem silliness.

For that i'll have to download the dirver. is it possible for me to change the kernel config or just recompile the kernel so that i am no more using the smp kernel and install the driver. will it work?

On a normal RedHat system both the uni-processor and SMP kernel are installed if the installer detects multi-processor hardware and Grub will be configured to default to the SMP kernel. To run the non-SMP kernel you simply need to select the other kernel on the Grub boot screen.

yeah thats the problem. actuall i don't have a smp machine but what happened was that when i first loaded linux grub didn't load properly so i installed a new kernel using the cd so that i could reinstall the boot loader (grub). so grub now doesn't give me the non smp option.
i want to rectify this problem whiout using the cd.
thanx

That's easily enough fixed. First you want to check /boot and /lib/modules to make sure that you have the files associated with an uni-processor kernel on the system. They should be there if your "fix" only installed the SMP kernel. Then you need to edit /boot/grub/grub.conf and add a stanza for the unit-processor kernel. Right now your grub.conf might contain a boot stanza something like:

title Red Hat Linux (2.4.20-20.7-SMP)
        root (hd0,0)
        kernel /vmlinuz-2.4.20-20.7-SMP ro root=/dev/sda2
        initrd /initrd-2.4.20-20.7-SMP.img

Adding a boot stanza like:

title Red Hat Linux (2.4.20-20.7)
        root (hd0,0)
        kernel /vmlinuz-2.4.20-20.7 ro root=/dev/sda2
        initrd /initrd-2.4.20-20.7.img

Before the SMP stanza will make the default boot be to the uni-processor kernel.
