The IDE controller comes first. The kernel uses the disk controller
drivers it has available to try to detect and begin communicating with
the disk controller. This has to happen before the kernel can get
anything (ie the partition table) from the disk. Next the kernel
reads the partition table and tries to interpret it. If the partition
table support is missing, then at that point the kernel will panic.
After reading the partition table, the kernel proceeds with reading
the filesystem. (if support for the filesystem on that partition is
missing the kernel panics at this point)
