Hello,

yesterday I installed FreeBSD 1.0. I have a SCSI disk and an IDE disk.
To prevent problems I disabled the IDE disk in the BIOS.

I installed FreeBSD successfully on the SCSI disk, on which there is also
another operating system (Linux) consisting of 3 partitions,
so the FreeBSD partition is 'DOS' partition 4 starting
at 600MB (it is a 1 GB disk).

I saw with fdisk that this 4th partition was made active by the installation.
However, since I always booted from the IDE drive, there was no MBR present
at all on the SCSI disk. I think FreeBSD also didn't install one because
I didn't use the whole disk for it. So I did a fdisk/mbr from DOS which
installed the standard MBR on the SCSI drive. I made sure the FreeBSD 
partition was still active, and tried to boot from the SCSI drive (IDE
drive still disabled).

However, the system prints "Mission operating system" (or something like that)
and then halts. It seems like the MBR tries to boot from the FreeBSD 
partition but it doesn't recognize a valid operating system there, 
understandable because DOS won't recognize FreeBSD.

Do I need a special MBR present to be able to boot? If so, how do I install 
it? 

Thanks in advance,

Eloy
