Very Computer

I have a Solaris x86 2.4 system with an 810 MB IDE disk.

Here is what I am trying to do:

1. Install a 2.9 GB SCSI disk on my Adaptec 1542B SCSI controller.
2. Partition it cylinders 0-959 for DOS, and 960-2736 for Solaris,
   (keeping cylinder 960 for the boot and 961-1016 for /)
3. ufsdump the filesystems from the IDE to the SCSI.
4. installboot to create the boot record on the SCSI
5. Remove the IDE and "Dual-Boot" DOS and Solaris.

Here is what has happened:

1. The DOS partition is working.
2. The Solaris partition is created (ufsdump and installboot)
   (the /etc/vfstab needed mods from c0d0s0 to c0t0d0s0 etc.)
3. The solaris boot partition menu selection starts.
4. I have tried three things to get the Solaris partition to work:
   1. Run Solaris format, ufsdump, and installboot
      error = Not a UFS Filesystem
   2. Boot from CDROM, Install core system support, reboot before
      ufsdump
      error = cannot load (kd)?
   3. Perform ufsdump on above core system support to copy files
      error = boot: source: cannot load (/etc/bootrc)

Each time I try this, I use BIOS to enable and disable the Hard Disk
(IDE).

One other really annoying problem is I can only get the distribution
boot floppies (or DU8) to boot if I have my IDE drive configured. If I
disable it and remove the IDE controller, I get MDBexec Load error and
the floppy boot halts.

Any help? Is moving from IDE to SCSI causing some of my headaches?

Thanks.

You also need to modify the boot-path property set in /etc/bootrc, and
the instance records in /etc/path_to_inst, and create the file called
/reconfigure on your new root filesystem.  The IDE and 1542 each only
have a single possible configuration so I think you only need to change

You have to type the boot drive number: 10 (assuming the adaptec is your
only SCSI adapter).  Also, some motherboard BIOSes won't fully disable
an embedded IDE controller.
