I got two replies. Thanks to Ning Zhang and Joel Lee.

 o Ning Zhang <>
        there is a possibility that your IRQ setting has conflict. If you
        can't find problem from Solairs side, check cmos and the irq setting.

 o Joel Lee <>
        Under the CMOS, did you specify of the existence of these changes?

Neither of these were my particular problem. I kept trying different things
and when I enabled the verbose flag in the Secondary x86 boot loader I saw
the reference to "/etc/bootrc". Not being as experienced with Solaris x86 I
wasn't aware of this file.

I found a reference to it in the SunSoft ``Solaris 2.5.1 x86 Device
Configuration Guide,'' in Appendix A, Post Installation Configuration, pages
45-47. It describes how to reconfigure the system to move an EISA adapter.
In my case it was the SCSI target ID, but the concepts are the same.
I performed the following steps to switch the SCSI target ID from 0 to 1.

    1. edit /etc/bootrc and change the line

            setprop boot-path /pci@0,0/pci9004,8078@12/cmdk@0,0:a
            setprop boot-path /pci@0,0/pci9004,8078@12/cmdk@1,0:a

    2. Saved /etc/path_to_inst as /etc/path_to_inst.sav and created
        a new file with a single line containing a `#' character.

    3. Edited /etc/vfstab and changed the string /c0t0 to /c0t1.

    4. touched /reconfigure.

    5. Rebooted the system.

The system is now running great with Windows NT 4.0, Linux 2.0.31, and
Solaris 2.5.1 installed. I'm using the Linux LILO loader as the master
boot loader with options for all three OSes.
