Fedora Users — Fedora Core wiil not install

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
