*    These drives do not directly support Photo CD.  However, by adding
     /XAEMUL to the ASPICD.SYS command line, in your CONFIG.SYS, we will
     emulate support for single-session Photo CD on these drives.

**   This drive does not support parity.  Please consult the troubleshooting 
     section of the users manual for information on using this drive.

***  These jukebox CD-ROM drives are fully supported.  A drive letter will
     be assigned for each CD.

3.  Tape Drive Support
=-=-=-=-=-=-=-=-=-=-=-=

SCSI-based 1/4 inch cartridge drives:
  -  Conner/Archive - All
  -  Wangtek - 250, 525, & 1 GByte
  -  Tandberg - 250, 525, 1 GByte, & 2 GByte

4 mm DAT drives:

  -  Hewlett-Packard
  -  WangDAT
  -  Sony
  -  Exabyte

8 mm drives:
  -  Exabyte - 8200, 8200SX, 8500


=-=-=-=-=-=-=-=-=-=
4.  Scanner Support
=-=-=-=-=-=-=-=-=-=

Hewlett-Packard's driver for HP ScanJet II scanners is included with Adaptec
EZ-SCSI.  This driver is named SJIIX.SYS and is designed to function with
Adaptec's ASPI managers.

Installation of the driver is easy.  Simply run Adaptec EZ-SCSI.  Adaptec
EZ-SCSI automatically detects your HP scanner and installs SJIIX.SYS into
the appropriate section of your CONFIG.SYS file.  You can then install
HP's DESKSCAN software if it is not already installed.

SJIIX.SYS supports the following applications using TWAIN or the
application's scanning utility:

Aldus: PhotoStyler
Arkenstone: Arkenstone Reader II
Caere: FaxMaster, OmniPage Direct, OmniPage Professional, PageKeeper
Calera: TrueScan, WordScan, WordScan Plus
Corel: Corel Draw
Delrina: WinFax, WinFax Pro
Eclipse systems: Eclipse fax
ExperVision: TypeReader
Image-In: Image-In
Intel: Satisfaction
Light Source: Ofoto
Micrografx: Picture Publisher
Pixel Translations: Open Book
RIX Software: WinRix
Westbrook: File Magic
WordStar/ZSoft: Publisher's Paintbrush, PhotoFinish

5.  Floptical Support
=-=-=-=-=-=-=-=-=-=-=

ASPIDISK.SYS has been modified to support Insite and IOMega floptical
drives.  For those of you already familiar with ASPIDISK.SYS and AFDISK.EXE,
using floptical drives is a bit different.  Do NOT use AFDISK.EXE to
format media inserted in your floptical drive.  You can use SCSIFMT.EXE
to low-level format the media if necessary.  To do a DOS format of your
media, simply insert the media into the floptical drive and run the DOS
FORMAT utility (run EZ-SCSI first).


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
6.  SETUP Command Line Options
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

There are a couple of command line options that are available with the
Windows version of EZ-SCSI (SETUP.EXE):

Option:        noctl3d
Example:       c:\setup noctl3d
Description:   EZ-SCSI for Windows uses a Dynamic Link Library (DLL) called
               CTL3D.DLL that gives its dialog boxes the 3-D gray-box look.
               This command line options disables the loading of this DLL.
               Note that EZ-SCSI defaults to not loading this DLL if you are
               using Central Point's Desktop (e.g. PC Tools for Windows 1.0).

Option:        noscan
Example:       c:\setup noscan
Description:   By default, EZ-SCSI will automatically scan your hardware for
               SCSI host adapters and SCSI devices.  In the unlikely event
               that this fails, we've provided an override switch that
               instructs EZ-SCSI to NOT scan for hardware.  It will simply
               decompress the files on to your hard disk.  You would then
               need to manually edit your CONFIG.SYS and/or AUTOEXEC.BAT.

7.  ASPIBUF.SYS
=-=-=-=-=-=-=-=

The ISA bus is limited to 24 bits of address.  2^24 = 16 MBytes.  What does
this mean?  It means that an ISA card that uses DMA cannot physically
access memory beyond 16 MBytes of RAM.  This is a limitation of the ISA
bus.

What do you do if you have an AHA-1540C with more than 16 MBytes of RAM?
Let's use Windows NT as an example.  Windows NT knows that the card cannot
access memory beyond 16 MBytes so it makes certain that all data transfers
occur within the first 16 MBytes.   Unfortunately, there currently is no
clean solution for DOS/Win 3.1.

The 16 MByte issue is not a limitation with PCI cards, EISA cards, VL cards,
or PIO cards.  It is only an issue with an ISA card that uses DMA such as
the AHA-1540/1542.  ASPIBUF.SYS is an ASPI double-buffering driver that
you load immediately after ASPI4DOS.SYS (e.g. before ASPICD.SYS, ASPIDISK.SYS,
etc.).  It, along with ASPI4DOS.SYS, must both be loaded low before EMM386
(or QEMM, 386MAX, etc.)  It intercepts ASPI and INT 13h commands and double-
buffers both so that these data transfers occur within the first 16 MBytes
of RAM.  ASPIBUF.SYS is intelligent enough to not double-buffer if the
ASPI or INT 13h buffer is already within the first 16 MBytes of RAM.  It is
only designed to work with ASPIDISK.SYS, ASPICD.SYS, and INT 13h commands.
Other ASPI drivers and/or applications may or may not work.  ASPI FOR
WINDOWS WILL BE DISABLED ONCE THIS DRIVER IS LOADED.

By default, ASPIBUF.SYS will allocate a 16K buffer for double-buffering.  You
can specify the size (2K-64K) by using the size= command line switch.  For
example:

device=c:\scsi\aspibuf.sys /size=8


=-=-=-=-=-=-=-=
8.  Limitations
=-=-=-=-=-=-=-=

o  EZ-SCSI for Windows (SETUP.EXE) will not load it's 3-D look DLL (CTL3D.DLL)
   if you are using Central Point PC Tools for Windows Desktop.

o  If you are using any device drivers which install the drive you have
   installed EZ-SCSI to, such as Stacker, Double Space, Ram disks, network
   drives, removable drives, etc., then be sure to edit your config.sys file
   so that your load line for Adaptec's drivers point to an existing drive.
   We recommend that if possible, you install EZ-SCSI to your very first
   boot drive.
