Fedora Core wiil not install

["R. Carrara" <rcarrara@xxxxxxxxxxxx>]

Hi - Fedora will not install on my PC. I'm trying to install Fedora 
using the CD ROM on a hard drive specifically to hold only Fedora.  The 
installation runs smoothly up to and including entry of the root 
password.  After entering the root password, a message appears 
indicating that it's reading the packages, and then it stops 
installing.  About 10 - 15 minutes later, the following error message 
appears  "You are trying to install on a machine which isn't supported 
by this release of Fedora Core".  I've tried both the graphical and text 
installations, a different video card (Voodoo 3) & CD ROM, and removed 
the sound card & modem, and Fedora will not install. Here are my PC's specs:
Motherboard: AOpen AX59PRO
CPU: AMD6-K2-500 MHz
Mouse: Microsoft Intellimouse PS2
RAM: 512 Megs
Sound card: SB Live
Hard drive: Maxtor 20 GB
Video: Diamond Viper V770 (RIVA TNT2)
Modem: AOpen FM56-PM
NIC: Netgear NC100
LG CDRW 32x10x40x
LG DVD 16x

Mandrake 8.1 &Knoppix  install without any problems. Any help that you 
can provide to install Fedora would be greatly appreciated.

Thanks,
Ron
