Many Windows 95/98 installation problems are due to IRQ's not being
enabled properly.  The subsequent sections will guide the reader
through common setup steps to enable IRQ's and general Windows 95/98 and
driver questions.


System CMOS setup hints:

The following section describes setup steps to take with 3 common
System CMOS's.

These are general procedures, since each Mother Board Vendor modifies
the BIOS to configure their Mother Board. To get the best results it is
best to set Network cards to IRQ 9.  This can be done via the software
that comes with the card.  Also set Sound cards to use IRQ 5.  For
detailed instruction for CMOS setups contact the Mother Board
Manufacturer.


Award BIOS

1)	While in the CMOS setup pick the "PCI Configuration Setup" or
      "PnP and PCI Configuration" menu. Change the settings for the
      slot number in which the Symbios Host Bus Adapter (HAB) is
      located if this option is available from "Auto Detect" to "INT
      A" or to an IRQ such as 10, 11, 12 or 15, leaving all other
      slots set to Auto. If there are no Slot options available then
      use the "MANUAL" setting.  This will show all of the IRQ's and
      will list them as either "Legacy ISA" or "NO/ICU" or "PNP/PCI"
      or "Yes/ICU".  What you will do is set all IRQ's below 9 to
      either Legacy ISA or NO/ICU.  IRQ's 10, 11, 12 and 15 will be
      set to PNP/PCI or Yes/ICU.

2)	The "Available IRQ" settings should be modified to 1st = 10,
      2nd = 11, 3rd = 12, and 4th = 15. Ensure that any other device
      in the system (i.e., sound card or LAN card) are not set to the
      same IRQ's as the Symbios Logic HAB. For example, if the LAN
      card is using IRQ 11, remove IRQ 11 as the 1st available IRQ in
      the CMOS setting and shift all of the available IRQ's up one
      level.

3)    Some versions have a statement that will say "PCI IRQ Activated
      by" set this to Level.  Some versions have a statement that will
      say "PCI IDE MAP to" set this to ISA or Absent.

4)	Save the configuration and reboot Windows 95/98.  Check the 
	performance tab located in the Control Panel->System Icon.
      Both file system and virtual memory should read 32-bit.


AMI BIOS

1)	While in the CMOS setup pick the "Chipset" or "Advanced" menu.

2)	Some versions of the CMOS setup allow for the setting of IRQ's
      referenced to the slot location of the Symbios Logic HAB.
      Other versions of the CMOS setup only allow for the IRQ to be
      set to "PCI/ISA" or "Used/Available". In any case, make sure
      that IRQ 9 is set to "Used", "not available", or "ISA".  Keep
      IRQ's 10, 11, and 15 free.

3)	Save the configuration and reboot Windows 95/98.  Check the 
	performance tab located in the Control Panel->System Icon.
      Both file system and virtual memory should read 32-bit.


Phoenix BIOS

If you have the version of the Phoenix BIOS, that only has 2 pages to
the CMOS setup and the only option for the SCSI is to enable or disable
it.  There is not much that can be done other than this.  The system
will do an Auto setting on its own.  There is NO work-around to fix the
problem.  The only solution is to go to another SCSI card.


***********************************************************************

Most OEM cards that use our chipsets are not "TRUE" plug and play
PCI-SCSI Host Adapters, that is why the manual settings of the IRQ's in
the system is required.

If you have an OEM Host Adapter, then you should contact the OEM first
before contacting LSI Logic.  You can find OEM number at the following
URL.

OEM SCSI HAB's with Symbios chips

All OEM HAB's that have jumpers for the setting of INT A, B, C, D must
be set to INT A.  This is generally pins 1&2.  

LSI Logic sells the controller chips to other vendors. Problems that we
have encountered with specific vendor HAB's are listed below.

All of these old OEM cards, while they may still be compatible to LSI
Logic software, may not be compatible to newer versions of Windows 
95/98.  It is recommended that you upgrade to a PnP style PCI-SCSI 
card.

MS-3805 HAB:
JP2 comes default as INT A Edge pins 2&3. Change JP2 to INT A Level,
pins 1&2.


GA-410 HAB:
JP3 is a setting for 1st controller and 2nd controller.  The card comes
default as pins 1&2.  Change JP3 to pins 2&3, and the system will
register the IRQ.


SCSI-810P HAB:
J1 comes default as INT B, pins 2&3.  Change J1 to INT A, pins 1&2.


Model P810 HAB: or
PCI-SCSI 21-050020-11 HAB:
This card will not allow an IRQ setting to be enabled for the Symbios
Logic controller (which it needs for proper operation for Windows 
95/98).  There is no work around for this card in Windows 95/98.


HSB KW801V10 HAB:
This card will not allow an IRQ setting to be enabled for the Symbios
Logic controller (which it needs for proper operation for Windows 
95/98).  There is no work around for this card in Windows NT*.

* Note: The HSB card does allow IRQ's to be enabled if the host system
is an Intel P5-66, a FIC P5-66, or a HSB motherboard. We were able to
get the chip to see an IRQ on an old Intel Batman system P/66 and a
P566 FIC Mother Board.  HSB also has informed us that their Mother
Boards also allow for an IRQ setting.


***********************************************************************

If the Symbios PCI-SCSI chip is embedded onto the mother board, then
you need to contact the mother board manufacturer for support on all
issues related to hardware and software.

General Questions And Answers

Q:	I am running a CD-R application and it cannot properly burn a
      CD.  Do I need a newer driver?

A:	This issue is related to our driver and CD Creator by Adaptec.
      We have found that in most cases the program will work.  Go to
      this site:

	http://www.adaptec.com/cgi-bin/cdrmain.cgi

	This page on Adaptec's site has a trouble shooting guide that
      will help in most cases.  Issue's found can be related from
      firmware upgrades to the device or even upgrades to the
      application.  If you are having problem then refer to this page
      first.


Q:	Windows 95/98 is on my system, but it will not recognize the
      CD-ROM.  Which driver do I load for the CD-ROM?

A:	The driver that is loaded during the installation of Windows
      95/98 is the driver for the SCSI controller.  Windows 95/98
      loads its own SCSI CD-ROM driver when it detects that device.
      Some of the problems with detection are caused by our SCSI DOS
      drivers being loaded in the CONFIG.SYS which Windows 95/98 will
      try to use during the boot process. Rename the CONFIG.SYS and
	AUTOEXEC.BAT to something else (i.e., CONFIG.OLD and
      AUTOEXEC.OLD) and reboot Windows 95/98.  Another possible
      problem is that the IRQ might not be set properly in the CMOS
      setup of the System BIOS.  Refer to the System CMOS setup
      options of this document for additional information.  After
      configuring the System CMOS, reboot the system, and Windows
      95/98 should detect the CD-ROM.


Q:	I have a ISA card that has your 53C400 or 53C400A or 53C416
      chip on it and need drivers to support the card.  Where do I
      get them?

A:    We provide drivers for the 53C400A (HP version) and the
      Symbios SYM20401, 20402 and 20403 that have our 53C416 chipset
      on them.  These drivers are located on the LSI Logic web site
      at this address:

      http://www.lsilogic.com/products/download1.htm

      We did not write any drivers for the 53C400 chipset, or any
      other cards that have the 53C400A chipset.  The chips are sold
      to OEM's that build their own card and write their own drivers
      for the cards.  You will need to contact the vendor of the
      device that came with the card for any software or hardware
      support.


Q:	I need an ASPI driver to function devices outside of the hard
      drive?

A:	We do not provide the ASPI driver under Windows 95/98.  If the
      driver does not come with application then your only solution
      is to go with another Host Adapter that provides an ASPI driver
      under Windows 95/98.


Q:	My scanner is not being seen by Windows 95/98.  What driver do
      I load?

A:	The Scanner Manufacturer provides the Windows 95/98 interface
      driver.


Q:	Windows 95/98 will not install to my SCSI hard drive.  I get an
      error that it cannot find any SCSI devices.  How do I get 95/98
      to install?

A:	Check in the System CMOS setup and look for VIRUS WARNING:
      ENABLED.  Disable this before starting the installation. Also
      disable any power management features during installation.
      After successfully installing Windows 95/98, you may re-enable
      both features.


Q:	What driver do I load for an NCR Computer that has a built-in
      53C700 SCSI interface?

A:    Windows 95/98 has a driver bundled in that supports the NCR
      computer.  If you are experiencing problems, call NCR/AT&T at
      (800) 774-7406.


Q:	What driver do I load for Windows 95/98 that supports a video
      card using a 77C22E, 77C22E+, 77C32BLT?

A:	There is no driver available for Windows 95/98 support.  The
      only option is to get another video card that is supported
      under Windows 95/98.


Q:	I get a (yellow exclamation mark (!) on the SCSI Host Adapter)
      and Windows 95/98 says that some drives are using MS-DOS
      compatibility mode?

A:	This is also known as a Code 10 error.  This problem is related
      to an IRQ conflict.  Please refer to the System CMOS setup
      options section to trouble shoot the IRQ problem.


Q:	I get a Code 22 (red circled X on the SCSI Host Adapter) and
      Windows 95/98 says that it can not detect, or there is a
      problem with the Host Adapter card?

A:	This problem can be fixed by double clicking on the Host
      Adapter controller in the Control Panel ->System Icon ->
      Device Manager .  This will bring up a Properties Screen.  The
      first page is the General page.  At the bottom of this page is
      a check box that reads Original Configuration Current).  Click
      on the box, which will place a check mark in it.  Now click on
      the OK button at the bottom of the screen.  Reboot the system.
      After rebooting into Windows 95/98, check the Performance Tab
      located in the Control Panel -> System Icon.  Both File System
      and Virtual Memory should read 32-bit.


Q:	Which driver do I use for a Compaq System with a Symbios Logic
      PCI-SCSI chip embedded?

A:	We provide a driver for Windows 95 for Compaq systems using our
	chips.  The driver can be downloaded from our PCI-SCSI download 
	page:

	http://www.lsilogic.com/products/pci_sw.htm?agree=Agree

	Under Windows '95 and '98 you will see a link to Download 
	Compaq Drivers.  The package is called COMPAQ95.ZIP.  You will 
	have to contact Compaq for Windows '98 drivers.  Other then 
	providing the '95 driver, all support for the Compaq Systems 
	with our chipsets embedded are supported by Compaq.

General Notes

1)	All Symbios PCI SCSI HAB's must be set to INT A, even if there
      are 2 or more cards being used.

2)	The 53C810 HAB's DO NOT have a BIOS on the card.  They rely on
      the System BIOS for SCSI BIOS support. If you do not see a
      banner during boot up then your system does not support our
      chips.

3)    The Current Windows 95/98 driver can be downloaded from either
      the BBS at (719) 533-7235 or at the Web site (www.lsilogic.com)
      click on the Symbios Driver Info located on the left hand side
      of the page.  Then click on the Download PCI-SCSI Drivers and
      Software.  Go to the bottom of the License Agreement and agree
      the to terms of the software to proceed.  The file name is
      WIN9598.EXE or .ZIP.  The .exe file is a self extracting file 
	for 95/98 or NT systems.  If you are using just DOS then 
	download the .zip package and be sure to have a program such as
	PKUNZIP to extract the files.

4)	If you are using a SCSI HAB that has 3 SCSI ports, you can only
      use 2 ports at one time.  If you are using all 3 ports and
      experiencing problems, then you need to remove the devices
      from one of the ports and hook those devices up to another
      controller.
