Adaptec EZ-SCSI 1.x/2.x to EZ-SCSI 3.0 Upgrade
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
=-=-=-=-=-=-=-=-=-=-=
How to run PATCH.EXE
=-=-=-=-=-=-=-=-=-=-=
This program will upgrade your EZ-SCSI ASPI managers (from EZ-SCSI 1.x
or EZ-SCSI 2.x) to EZ-SCSI 3.0. The version of EZ-SCSI you have is
printed on your floppy label. In addition, users of EZ-SCSI 2.x will
also have their CD-ROM driver updated to the EZ-SCSI 3.0 level
(ASPICD.SYS). To upgrade, type:
PATCH C:\SCSI
where C:\SCSI is the location of your previous EZ-SCSI installation.
If you would like to view which files were updated, you may want to
redirect the patch program output to a file. For example, to redirect
to EZPATCH.TXT, type:
PATCH C:\SCSI > EZPATCH.TXT
Backups of the older versions will be stored in an OLDSYS subdirectory
(e.g. C:\SCSI\OLDSYS). Also included in this subdirectory, you will
find UNPATCH.BAK. You can rename this file to UNPATCH.BAT and run it
if you wish to restore your drivers to the previous version.
If you run Microsoft Windows, you should copy the files WINASPI.DLL and
VASPID.386 to your Windows' SYSTEM subdirectory. For example:
COPY C:\SCSI\VASPID.386 C:\WINDOWS\SYSTEM
COPY C:\SCSI\WINASPI.DLL C:\WINDOWS\SYSTEM
NO changes to your .INI files are necessary (e.g. SYSTEM.INI).

the AHA-2740W/2742W)
o Removable media lock/unlock/eject utility, RMVTOOL.EXE (DOS command
line utility)

* 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.
** These drives do not support parity. Please consult the troubleshooting
section of the users manual for information on using these drives.
*** These jukebox CD-ROM drives are fully supported. A drive letter will
be assigned for each CD.

SMARTDRV 5.0 and XA formatted CDs
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
SMARTDRV 5.0 (in MS-DOS 6.2, Windows for Workgroups 3.11) now includes
caching for CD-ROM drives. There is a problem with SMARTDRV in its support
for XA formatted Compact Discs. If you experience "Not Ready" errors,
using SMARTDRV 5.0, add /E:2048 to your SMARTDRV command line. For example:
C:\DOS\SMARTDRV /X /E:2048

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.
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 APPLICATIONS (E.G. SHOWSCSI.EXE) 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
NOTE: This driver was not available with previous versions of Adaptec
EZ-SCSI but will still be decompressed to your hard drive when you run
the PATCH program.
