FC 8/9 IDE problems on Ampro LX800 board...

What is the kernel message exactly? Does it say "ata2: Disabled by BIOS",
or what is the exact message line from kernel log? That would help locate
the exact check in the code that makes it disabled

Among other things it checks if the channel has been enabled by
firmware/BIOS, by reading the appropriate MSR register. If that is not set
up for the given ata channel, it will not use it.
