SYNOPSIS:     Installation of Solaris x86 version 2.1 on an IBM PS/2 Model 95

OS RELEASE:   2.1

PRODUCT:      Solaris x86

KEYWORDS:     Install IBM PS/2 95


DESCRIPTION:

Cannot get Solaris to load/boot from my IBM PS/2 Model 95, or get
OpenWindows to display on my IBM 9515 XGA monitor. 


SOLUTION:

During installation, the MDB boot diskette may find the appropriate SCSI
target ID's but complains about not being able to load /kernel/unix, or
A narrow horizontal band appears on the screen when initiating the
openwin command. 


Workaround -

Before installation, make sure that the SCSI hard disk to be installed
is at target ID 6, that the CD is set somewhere in the range of target
ID 0 through 5, and that your XGA monitor is capable of displaying both
the 72 Hz and 75 Hz vertical refresh rates.  (i.e.  NEC Multi-sync 5FG)

Resolution -

A more concise and detailed description follows as to how to properly
install Solaris 2.1 x86 on an IBM PS/2 Model 95:

First of all, you will need to know the system type:

Remove the front panel and look under the display, there should be a
type specification there. 

Also, boot the computer with the IBM reference diskette and have any
required options disks handy.  Once in the config.  program, write down
the following information:

              BIOS Part Number and Date
              System Model and Sub-model
              Revision level (last line)


Next, write down the make and model number of your CD ROM drive. 

Note that if you're using an IBM MCIS SCSI controller rather than the
Adaptec 1640, the installation of the operating system is only supported
when the hard drive for the system is supplied exclusively by IBM to be
used specifically with the MCIS adapter. 

Now enter the configuration sub-menus and set the port address for the
SCSI controller to 3540-3547, DMA level 3, fairness on, enable ROM WAIT,
and insure that the target ID for the controller is 7.  If you require
an alternate port address setting, please call the Intellisystems
automated supported system for updated information on this. 

Your XGA video controller should reside at port address 2160-216F. 

Before entering the "Set Configuration" sub-menu, insure that your SCSI
disk is set to TID 6 and your CD ROM drive may be set at any target ID,
preferably 0. 

Once in the "Set Configuration" sub-menu, choose "Set and View SCSI
Device Configuration" to verify that the system sees all SCSI devices at
their appropriate Target ID's. 

Now install Solaris normally.  The MDB boot screen should show the MCIS
BIOS extension to reside at address 9D40.
