Troubleshooting Tips
====================
ASPI2DOS.SYS
------------
ASPI2DOS.SYS is the Adaptec ASPI manager for AIC-6260/6360/6370 based SCSI
host adapters. Adaptec EZ-SCSI automatically detects which
host adapter you have installed, which ASPI manager needs to be loaded,
and what the correct command line switches are.
o If you are using an Adaptec APA-1425/50/50A/60/60A SlimSCSI, make sure you have
PCMCIA Card & Socket Services installed BEFORE running Adaptec
EZ-SCSI.
o If you have an IBM ThinkPad 360Cs or an IBM ThinkPad 755, and are
using the Adaptec APA-1425/50/50A/60/60A SlimSCSI, you need to move the following
line to the last line inside your CONFIG.SYS file:
DEVICE=C:\EZPLY\$ICPMDOS.SYS
Note: If the directory for EZ-Play is different than the default, use
that directory instead. The above line uses the standard directory as
an example.
o If you have an APA-1425/50/50A/60/60A (SlimSCSI) in your system and are installing
ASPI2DOS.SYS manually, you will need to add the following command
line switch to ASPI2DOS.SYS in your CONFIG.SYS file:
DEVICE = C:\SCSI\ASPI2DOS.SYS /D /PCMCIA /Z
o If you cannot suspend/resume properly on an AcerNote 735c, with an
APA-1425/50/50A/60/60A (SlimSCSI), you're probably experiencing an I/O conflict
between the APA-1425/50/50A/60/60A and your laptop. The AcerNote uses port 35F for
video control. You'll need to manually exclude this I/O port. With
SystemSoft Card and Socket Services, you can do this by editing the
CSALLOC.INI file and adding the line:
ioexclude=35F
o If you are using the Gateway 2000 Colorbook laptop with an Adaptec
APA-1425/50/50A/60/60A (SlimSCSI), ASPI2DOS.SYS may fail during driver installation.
If you encounter this problem, you will need to run the CMOS setup utility
and disable the "FastBoot" option.
o The following note only applies to users with SCAM capable SCSI devices. Please ignore
it if you do not have such a device.
SCAM stands for "SCSI Configured AutoMagically." With SCAM support,
a host adapter can determine which SCSI IDs are not in use, and assign
a free ID to a SCAM capable SCSI device.
Normally SCAM is not enabled, and you need to set switches on the back of all of
your SCSI peripherals to assign them unique SCSI IDs.
You can enable SCAM support by adding /SCAM+ to your ASPI2DOS.SYS command line.
For example:
DEVICE = C:\SCSI\ASPI2DOS.SYS /D /SCAM+
This will work with any AIC-6260/6360/6370 based SCSI host adapter
that does not have a BIOS enabled on the host adapter. If the host
adapter has a BIOS, and it is enabled, the command line switch is
ignored. If you have a SCAM capable BIOS (e.g. AHA-1530P), then you
can enable or disable SCAM support by running SCSISelect.
ASPI8DOS.SYS
------------
ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7855/7870 based
PCI SCSI host adapters. Running Adaptec EZ-SCSI will automatically
detect which host adapter you have installed, which ASPI manager needs
to be loaded, and what the correct command line switches are.
o If you have an Adaptec PCI SCSI host adapter installed in your system,
and you have EMM386.EXE loaded from MS-DOS versions up to 6.2, your
system might hang if loading the ASPI manager after EMM386.EXE. This
has been fixed in the EMM386.EXE that ships with MS-DOS 6.22 and
later. If you experience this problem, you will either need to load
ASPI8DOS.SYS before EMM386.EXE, or upgrade to MS-DOS 6.22 or later.
If the ASPI manager detects a conflict, a message will be shown
explaining how to work around the problem. Other ASPI modules
(e.g. ASPICD.SYS) can continue to be loaded high.
o There are several techniques for a driver to determine if its PCI SCSI
host adapter is installed in your system. ASPI8DOS.SYS will determine
which is the best method, and has been written to work around the
EMM386.EXE problems discussed above. There are three command line
switches you can use to force the ASPI manager to use a specific
method. These are:
/MB - This command line switch will force the driver to use the
PCI BIOS calls (INT 1Ah) to scan for PCI SCSI host
adapters.
/M1 - This command line switch will force the driver to use the
"Mechanism 1" method for scanning for PCI SCSI host
adapters.
/M2 - This command line switch will force the driver to use the
"Mechanism 2" method for scanning for PCI SCSI host
adapters.
For example, if you want to force the ASPI manager to find your PCI
SCSI host adapter using PCI motherboard BIOS calls, your CONFIG.SYS
would be:
DEVICE=C:\SCSI\ASPI8DOS.SYS /D /MB
NOTE: Most PCI systems do not support all three methods for scanning
for PCI cards. It is recommended that you let the ASPI manager
determine which method is suitable.
o If you would like ASPI8DOS.SYS NOT to reset the SCSI bus, during
driver initialization, you can use the /NORST command line switch.
For example:
DEVICE=C:\SCSI\ASPI8DOS.SYS /D /NORST
If you would like ASPI8DOS.SYS to always reset the SCSI bus, during
driver initialization, you can use the /RESET command line switch.
For example:
DEVICE=C:\SCSI\ASPI8DOS.SYS /D /RESET
o If there are more host adapters that ASPI8DOS can support, ASPI8DOS will display "Not enough
memory for all host adapters". In this case, the user should manually add more lines of
"DEVICE=ASPI8DOS.SYS" to CONFIG.SYS to support the extra host adapters. EZ-SCSI only installs one entry in config.sys for ASPI8DOS.SYS.
MCAM18XX.SYS
------------
MCAM18XX.SYS is Adaptec's ASPI manager for its AHA-2920/2920A PCI SCSI Host
Adapters. Running Adaptec EZ-SCSI will automatically detect which host
adapter you have installed, which ASPI manager needs to be loaded, and
what the correct command line switches are.
o The command line switches for MCAM18XX.SYS are currently not documented
in our on-line "Device Driver Reference" Windows help file. The
following command line switches are supported:
/u- - Force Asynchronous Data Transfers on a Host Adapter.
/norst - Disables Hard Reset during initialization.
/y - Disables parity checking.
/m1 - Force PCI bus scanning using the "Mechanism 1" method.
/m2 - Force PCI bus scanning using the "Mechanism 2" method.
/mb - Force PCI bus scanning using INT 1A.
/l - Enable multiple LUN support
o If installing the AHA-2920/2920A under Windows 3.1/3.11, Adaptec EZ-SCSI
will automatically install the AHA2920.386 and AXPT.386 device drivers.
The following options are supported by AHA2920.386. To enable an
option, add the following to the [386Enh] section of your SYSTEM.INI
file:
AHA2920 = [/l-] [/u-] [/y]
/l- - Disables multiple LUN support.
/u- - Force Asynchronous Data Transfers on a Host Adapter.
/y - Disables parity checking.
The following options are supported by AXPT.386. To enable an option,
add the following to the [386Enh] section of your SYSTEM.INI file:
EZSCSI_OPTIONS = [/d]
/d - Displays version, adapter, and device information.
MA358.SYS
---------
MA358.SYS is Adaptec's ASPI manager for its APA-358/358A parallel port
SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect
which host adapter you have installed, which ASPI manager needs to be
loaded, and what the correct command line switches are.
o MA358.SYS, by default, will automatically detect the type of parallel
port you are using. You can use the /Mnm switch to force a specific
mode, and to set the amount of time that the MiniSCSI "Fast" read and
write cycles are delayed (parallel ports on some computers require
delays). You must specify values for both 'n' and 'm'.
The 'n' specifies the amount of delay. Allowable values for 'n' are 0
through 7, with each number representing a 125-nanosecond (ns)
increment. A value of 7, for example, adds an 875 ns (7x125) delay to
the cycles. The default of 0 specifies no delays.
The 'm' parameter determines the mode. The allowable values are shown
in the following table:
Value of 'm' Meaning
------------ ------------------------------------------------------
0 Auto-detect mode (the default). Automatically detects
the type of port and configures the APA-358/358A for
EPP if that port is detected to support EPP mode,
otherwise the port is set up as a standard parallel
port.
2 Forces unidirectional mode.
4 Forces bidirectional mode.
8 Assumes EPP 8-bit bidirectional mode. For this to
work, the parallel port must be set for EPP mode in
the CMOS setup program or by configuring jumper
settings on your EPP I/O card. For instructions on
using the CMOS setup program, see your motherboard
documentation. For instructions on configuring
jumpers on your EPP I/O card, see your EPP I/O card
documentation.
For example, if your parallel port is configured for EPP mode, and you
would like the default read/write delay, your CONFIG.SYS would contain
the following:
DEVICE=C:\SCSI\MA358.SYS /m08
If you change the MA358.SYS options in the config.sys file, turn the
computer OFF and then ON again to have the changes take effect. (Do
not simply reboot the computer using Ctrl-Alt-Del.)
o If you have an original NEC Ultralite Versa laptop, and MA358.SYS is
unable to detect the APA-358/358A SCSI host adapter, you should use
the /m20 command line switch. For example:
DEVICE=C:\SCSI\MA358.SYS /m20
o If you are using the APA-358 with an NEC Versa E or Versa V system,
which uses the Western Digital Super I/O chip for FPP Parallel Ports
(Chip #WD76C30), you should use the MA358NEC.SYS ASPI Manager in your
CONFIG.SYS file instead of the standard MA358.SYS ASPI Manager.
o If you are using an IBM ThinkPad 720 series computer, you should use
the MA358IBM.SYS ASPI manager in your CONFIG.SYS file instead of the
standard MA358.SYS ASPI manager.
o When using the APA-358/358A, you should not configure your parallel
port for ECP mode. Instead, you should configure the port for EPP
mode.
o MA358.SYS only supports one APA-358/358A in a system.
o If you are using the APA-358/358A, and you are backing up from a SCSI
disk drive to a SCSI tape drive, and you are using SMARTDRV, we
recommend that you disable SMARTDRV write caching. Leaving write
caching enabled can cause the backup to fail.

HARD DISK SUPPORT
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Windows 3.1/3.11 and DOS
------------------------
DOS and Windows 3.1x include built-in support for SCSI hard drives if your
new drive is under BIOS control (e.g. you booted from it). Please refer
to your host adapter documentation to learn more about whether or not
your SCSI host adapter includes an on-board ROM BIOS. In this case, you
can follow these steps:
1.) Boot to DOS.
2.) Run FDISK to partition your new drive as you desire.
3.) Reboot your operating system.
4.) Run FORMAT on your newly created drive letter(s)
If your new SCSI hard drive is not under BIOS control, you can follow
these steps:
1.) Install Adaptec EZ-SCSI for DOS
- Insert EZ-SCSI DOS/Win 3.1x diskette into a:\
- Run DOSINST.BAT
2.) Reboot your system.
3.) From DOS, run AFDISK.EXE which is located in your
Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI).
4.) Partition your new media as you desire.
5.) Reboot your operating system.
6.) At this point, your new drive is under ASPIDISK.SYS control
(Adaptec's disk driver for DOS).
7.) Although optional, we recommend that you run DOS FORMAT on your
new drive letter(s) so that the drive can be scanned for defects.

REMOVABLE DISK SUPPORT
=-=-=-=-=-=-=-=-=-=-=-=
Windows 3.1/3.11 and DOS
------------------------
To prepare your removable media for use under Windows 3.1/3.11 and DOS,
you can follow these steps.
1.) Install Adaptec EZ-SCSI for DOS
- Insert EZ-SCSI DOS/Win 3.1x diskette into a:\
- Run DOSINST.BAT
2.) Reboot your system.
3.) From DOS, run AFDISK.EXE which is located in your
Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI).
4.) Partition your new media as you desire.
5.) Reboot your operating system.
6.) At this point, your new drive is under ASPIDISK.SYS control
(Adaptec's disk driver for DOS).
7.) Although optional, we recommend that you run DOS FORMAT on your
new drive letter(s) so that the drive can be scanned for defects.
Below is additional information you may find useful:
o Adaptec EZ-SCSI supports both 512 byte/sector media and 1024 byte/
sector media.
o If you would like to reserve multiple drive letters for your removable
media, you can use the /r command line switch. For example, if you
would like ASPIDISK.SYS to reserve two drive letters for your removable
media, you would have the following in your CONFIG.SYS:
device=c:\scsi\aspidisk.sys /d /r2
o Support for the Panasonic PD drive is also included. Note that you
should leave this device jumpered in its default two LUN mode.

CD-ROM SUPPORT
=-=-=-=-=-=-=-=
Windows 3.1/3.11 and DOS
------------------------
Adaptec's CD-ROM driver for DOS/Windows, ASPICD.SYS, has been written to
support any SCSI-2 CD-ROM drive and most SCSI-1 CD-ROM drives. Simply
run Adaptec EZ-SCSI and the correct additions will be made to your
CONFIG.SYS and AUTOEXEC.BAT.
Adaptec EZ-SCSI has been tested with CD-ROM drives from the following
vendors:
AIWA
Compaq
Chinon
Denon
Goldstar
Hitachi
IBM
LMS
Matsushita
NEC
Panasonic
Nakamichi
Philips
Pioneer
Plasmon Data
Plextor
Ricoh
Sanyo
Sony
TEAC
Texel
Toshiba
Yamaha
Below is additional information you may find useful:
o The following drives do not directly support Photo CD:
Chinon CDS 431
Denon DRD 253
LMS (Philips) CM 214
NEC CDR 72
NEC CDR 74 (NOTE: 74-1 and 84-1 do support single-
NEC CDR 84 session Photo CD)
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.
o The following drives do not support parity:
NEC CDR 38
NEC CDR 55
NEC CDR 72
NEC CDR 73
NEC CDR 74 (NOTE: 74-1 and 84-1 do support SCSI parity)
NEC CDR 84
NEC CDR 210 (NOTE: 210P does support parity)
Please consult your host adapter documentation on how to disable parity
support on your SCSI host adapter.
o The following jukebox CD-ROM drives are fully supported:
Nakamichi MBR-7
Pioneer DRM 600
Pioneer DRM 604X
Pioneer DRM 624X
A drive letter will be assigned for each CD.
o Some older SCSI CD-ROM drives do not support synchronous negotiation
properly. If you encounter problems using your CD-ROM drive, try
disabling synchronous negotiation. Please refer to your host adapter
documentation on how to do this.
o In rare circumstances, you may encounter problems with Windows 3.x and
DOS reading your CD-ROM drive.
For example, you change the contents of the CD-ROM drive, but when you run
DIR, the contents of the previous CD is displayed instead of the new CD's.
Or you may see multiple drive letters assigned to your single CD-ROM drive.
One solution is to add the /NOLUN switch to the aspicd.sys line in config.sys.
We have seen the former problem with the Sony 55s - an older double speed
CD-ROM drive, and the latter problem with an older SCSI1 Panasonic drive.
By adding the /NOLUN switch, you will however loose support
for any CD Changers or PD drives that you also have connected to your PC.
