fedora 9 problem

[Lalit Singh Rawat]

Hi Group,
I bought a new "Toshiba Satellite-Pro P300 laptop" to run fedora 9 on it. I
have successfully installed it it. When i am trying to boot Grub is also
looking good. But after that nothing is happening, i mean kernel is not
responding properly. No lights are flashing which indicates about the
harddisk.
Even during the boot i have change the root to

ide=nodma pci=routeirg

It boot successfully twice  after that. But third time it is still not
booting.
Now i am wondering why it is not working.

Any suggestion would be appreciated.

Thanks
Lalit
