Hardware/mobo fakeraid, or Linux MD RAID (mdadm)? Please state mobo
brand and model#, as well as any IDE/SATA PCI/e cards.

SATA doesn't have "master" and "slave" designations, so I'd say you're
using IDE disks, or your system BIOS is funky. Also, Master and Slave
don't mean what you apparently think they do. These settings have
nothing to do with software, should not affect boot order, or how Linux
runs. In the world or IDE/PATA, you can have a single slave device on a
cable in absence of a "Master" device. Think of "Master" and "Slave" as
"0" and "1" instead. They are simply designations, but given horribly
bad names decades ago by engineers with brain damage.
Regardless, you should be able to configure the boot order in the BIOS
to do whatever you want, unless of course this is a really old PC.
