Alright here is my problem. I have a Athlon running at 333, with 128 Megs of ram. I'm trying to install linux on to this machine but keep on running into to the same problem. On trying to install it says

crc error
VFS: Cannot open root device "<NULL>" or unknown-block(8,5)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block(8,5)

the block locations change with the different root options I try, mostly the locations are 0,0. Also the <NULL> changes to what I try as the option, but you should already know that part.

These are the things that I have tried to do to fix the problem.
I have also tried installing redhat 9.0 and get the same problem.
-Different media disk(s)
-Different CD-ROM drive

Does anyone have any ideas?
There is only one partition on one drive.
