Description of problem:

Installing Fedora Core 4 on a ASUS K8S MX motherboard results in kernel 
panic. Happens before anaconda comes into play. 
I thought the error was perhaps related to the sis5513 ide controller. 
So, tried 'linux ide=nodma' and 'linux noprobe' with no change in error.

Error: 
SIS_IDE probe of 000:00:02.5 failed with error -1. 

A little later, these errors appear:

Could not open root device "<NULL>" or unknown block(8,3)
Please append a correct root =  boot option
Kernel Panic - not syncing 
VFS: Unable to mount root fs on unknown block (8,3) 

Version-Release number of selected component (if applicable):
Fedora Core 4 

How reproducible:
Always

Steps to Reproduce:
1. Get a ASUS K8S MX board
2. Boot from FC4 CD 
3. start installation
4. Kernel panic before anaconda. 
  
Actual results:
The  install process stops. 

Expected results:
Anaconda shud have started

Additional info:
The install of Fedora Core 3 works fine. 
linux ide=nodma or linux noprobe doesnt help.
