IDE vs SATA Jumper Settings

[techtronic]

In IDE, we use the jumper settings to distinguish Primary or Secondary Master and Slave Drives

But in SATA, there is no jumper setting. If we connect two SATA HDDs simultaneously to the motherboard, with each having its own OPERATING SYSTEM installed in it, then which one of the OS would boot. as we know that there can be only one MBR.

I found the option of choosing the SATA HDDs for booting in ASUS Motherboards by pressing the F8 key during startup

How can we choose this option in the other motherboards ?

I must make few things clear here first MBR is located on all the HDD.
and there is option for choosing HDD to boot from.By default the first SATA channel is used

I use multiple SATA drives on both my PC's. The BIOS's of my motherboards (Intel D 915 PGN and Intel D 101 GGC) have an option to select which drive to boot the OS from.

I do not use multiple OS's on a single system, so I cannot comment on that aspect.

Hope this helped
