This is indeed true. NetBSD is on the SCSI, Windows on the IDE. Windows boots
fine with both discs plugged in.

How do I write an MBR to the SCSI disc specifically ?  From DOS, I run
fdisk/mbr, but this has no impact.

Thinking about it though - I thought there was an MBR on the SCSI disc -
if I unplug the IDE drive, it boots fine. It is only when the IDE drive
is plugged in that NetBSD fails to boot.
