[Louis Garcia]

I had to reinstall windows and it override the MBR. How do I reinstall
grub on the MBR?

Thanks, --Lou

It's not easy.
First, boot from the cd1. Enter "linux rescue" at the lilo prompt.
This will mount the root partition to /mnt/sysimage (or something like).
Mount /boot partition to /mnt/sysimage/boot :
mount -t ext3 /dev/hda? /mnt/sysimage/boot

Disable exec-shield :
echo 0 > /proc/sys/kernel/exec-shield

Run grub-install. For example :
grub-install --root-directory=/mnt/sysimage /dev/hda

Take this pieces of advices very carefully ! Backup /boot partition.

I forgot to say that I have a boot disk. I can boot from the floppy. So
can I just do a grub-install --root-directory=/ /dev/hda when I'm in
linux?

If the problem is simply that Windows has overwritten the master boot
record, a simple grub-install /dev/hda should do it.

Here's something I've learned from working with grub.  Info grub will
tell you how to make a grub boot floppy.

That floppy has saved my backside more than once. It is a very useful
accessory.

Yep, that did it. Thanks

Sound not working on 2.6 kernel

[Thiago Vinhas de Moraes]

Hi.

I've downloaded the 2.6-test4 rpm from RedHat, and now the sound just
doesn't work on KDE.
I tried to run the redhat-config-sound, it detected the sound card and I
could hear the music it plays, but when I log in to KDE, I get the
following message:

Sound server informational message:

Error while initializing the sound driver:

device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device.

Any idea of how to fix this?

Regards,
Thiago

I had the same problem using vanilla-2.6.x ,alsa and emu10k1 
soundmodule. Turns out
the modules where not being loaded so I just did that manually (and 
edited modprobe.conf),
snd_emu10k1(my card), snd_pcm_oss,
snd_seq_oss (for oss emulation). That worked for me, hope it works for 
you too.

What exactly did you put on /etc/modprobe.conf. BTW, is this file new?
