FC4 Installation hang at start_kernel+0x15c/0x1b0

[Want to be a Fedora user!]

PC AMD Duron 750, 196MB RAM, IDE 2,5GB HD, Voodoo3 3000 video card.
Fedora Core 4, installation with the 4 CD
No USB periphericals

When I boot from the boot CD, I press enter to install in graphical 
mode (or with "linux text" the problem is the same), then I test the 
CD, all is OK, then the installation begin but it hangs 
systematically after the line :

[<c01010ae>] cpu_idle+0xe/0x50
[<c041677c>] start_kernel+0x15c/0x1b0


What can I do ?

Thank you very much for your help
