My systems all boot from the first IDE drive by default. If there is
no IDE drive some SCSI controllers (Adaptec 1452C is what I use) will
boot from the /dev/sd0 device. As far as I know there is no way to
boot from the SCSI if you have an IDE in the system without using
a boot manager like System Commander or lilo (for Linux). I've also
had some luck using the OS/2 boot manager (but no luck using OS/2
itself :-)
