known as SETUP.
What you are hearing about is the screens that show while booting after you have set everything up and enabled each of the sections that will have a drive on it.
Depending on the mobo, its chipset and any additioanl RAID like chip added to the mobo, and how you have set the SATA in the set up, it could show under IDE, or on a susbsequent screen for RAID, or another subsequent screen the other chip [such as SII for a Gigabyte mobo that I have].
The setup can be very confusing in these power mobos because there are so many ways to enable the SATA depending which chip's SATA port that one decides to use.
On my Giga you can even set it to remap to IDE. That's with the Intel 875p chipset, however mine is set to use the SII chip's SATA. [Intel's chipset offers two and the Silicon [SII] chip offers two [as well as each offering RAID].
I have drives on all three possible sections of the BIOS, thus while booting the normal IDE sections show first, then the Intel RAID section [only used for ATAPI drive], and then the SII section of the boot process.
I have been told that Serial ATA hard drives have there own BIOS if so where can i find it?
or have i got it all mixed up?
