I have a few asus MBoard systems with only one IDE-drive attached.
In my kernel bootup screen and in "dmesg" of these systems I get the following:
Uniform Multi-Platform E-IDE driver Revision: 6.31

Partition check:
hda: hda1
The system tries to detect IDE-drives that are not there.
Although the systems where I see these messages run without any problems,
the "failed" messages are a result of a timeout in the kernel bootup that
takes a considerable amount of time. And probing of IDE-drives, of which I
now they are not there, is quite useless.
I tried to change the BIOS parameters of the IDE-drives but this didn't
make a difference. This looks logical because as far as I know the kernel
doesn't use the BIOS to configure the system's hardware.
In order to speed up the boot process, how can I prevent this probing from
taking place.
