Initio INI-9XXXUW/Iwill SIDE-2935UW Device Drivers for DOS
----------------------------------------------------------
1. Overview
Under the Microsoft DOS operating System, the INI-9100UW/SIDE-2935UW host adapter
BIOS will provide the necessary functions to support SCSI hard disks. The BIOS
supports up to two hard disk drives for DOS 4.01 and below. It supports more
than two (up to eight) hard disk drives for DOS 5.0 and above.
You don't have to install a device driver to access the hard disk. However
you need to install ASPI(Advance SCSI Programming Interface) device driver to
support other SCSI devices such as CDROMs, Tape drives, or Scanners.
The Initio INICD.SYS driver is an ASPI compliant SCSI CD-ROM driver for DOS operating system.
The DOSSETUP utility will install the Initio ASPI device driver
(ASPI910U.SYS) for DOS 3.3.1 or later. It will also optionally install the
Initio SCSI CD-ROM device driver(INICD.SYS).
2. Installation Procedures
1. Insert the diskette into your floppy drive.
2. Change to the drive letter that contains the diskette.
(e.g., C:>A:)
3. Type DOSSETUP.
A:>DOSSETUP
3. ASPI Driver(ASPI910U.SYS) Command Line Options
The standard format for command line in the CONFIG.SYS file is:
DEVICE=C:\INIASPI\ASPI910U.SYS [Driver Config Option]
Driver Config Options:
/D Verbose mode provides detail information about driver when
driver is inititalized
/L Driver scan eight LUNs for each SCSI Target.
/Bx,yy Scan device only on PCI BUS x, DEVICE yy
The range for "x" is from 0 to 7.
The range for "yy" is from 0 to 20.
/Bx Scan all the devices on the PCI BUS x
The range for "x" is from 0 to 7.
/Syy Scan device only on the PCI BUS 0 & Device yy.
The range for "yy" is from 0 to 20.
/CCBSx Defines the maximum number of concurrent I/Os that driver
supports. The range for "x" is from 1 to 16.
3. CD-ROM Driver(INICD.SYS) Command Line Options
The standard format for command line in the CONFIG.SYS file is:
DEVICE=C:\INIASPI\INICD.SYS [Driver Config Option]
Driver Config Options:
/D:<name> Specifies a logical name to the SCSI CD-ROM device driver.
/Xx:y:z Exclude a specific CD-ROM drive(SCSI H/A #x, ID #y, Lun #z)
from being controlled by SCSI CD-ROM driver. When SCSI ID and
LUN are not specified, all devices on the supplied host
adapter number will be excluded.
/T Specifies the timeout after which SCSI CD-ROM Driver returns
an error when the CD-ROM drive is not responding. Valid
timeout values are 1 through 9 minutes. The timeout default
value is 3 minutes.
4. MO Driver(INIDISK.SYS) Command Line Options
This file contains Initio MO Driver Beta V.1.05 for MS-DOS and
Windows 3.1X. The driver as it is assumes a pre-partitioned
and preformatted cartridge in the removable drive.
INIDISK.SYS supports 512, 1024, and 2048 bytes per sector.
INIDISK.SYS User's Guide
========================
Inidisk.sys is a DOS block device driver for supporting SCSI fixed
disks, removable disks and MO devices. INIDISK.SYS must be loaded
by your CONFIG.SYS start up file. INIDISK.SYS requires that an
ASPI Manager be loaded. Therefore, you must load INIDISK.SYS
after you load the appropriate ASPI Manager. INIDISK.SYS can
be loaded with either the DEVICE= or DEVICEHIGH= command.
Below is a list of command line options and examples.
/R /r
=========
This option specifies the number of logical drives to
reserve for MO and removable disk devices. MO and removable
disks media are capable of being partitioned just like a
fixed disk. For every DOS partition on the media a logical
DOS drive letter will be available. INIDISK.SYS will support
as many logical drives as required (up to the maximum supported
by DOS) based on the partitioning of the media that is present
when your system boots. However, the media may be removed at
any time and a new disk may be inserted. The new disk may
have more (or less) partitions then the original disk.
The /R /r option is used to reserved drive letters at start
up in order to facilitate a disk change to a disk with more
partitions than the original disk present at boot time. The
value after the /R /r option determines how many drive
letters will be reserved on a device basis.
Example:
if the user specifies a /R4 option and there are two removable
devices attached to the SCSI bus, then a total of eight (8)
drive letters will be reserved.
/T /t
==========
This option is used to specify a Time out value to be used
when sending commands to a SCSI drive. If a SCSI drive does
not respond to a command within the specified time out then the
command will be aborted and an appropriate error message will
be displayed. The time out value is specified in minutes.
Valid values are 1-9 and D or d. The D or d values are used to
Disable the time out mechanism. If the time out mechanism is
disabled then faulty hardware can lock up the system.
Examples:
/T4
/Td
/TD
/T1
/X /x
=========
This option is used to eXclude particular SCSI drives.
Excluded SCSI drives are identified by specifying the host
adapter, target id and lun. These values are spereated by
a colon. Groups of SCSI drives (or wild cards) can also be
identified.
Below are examples of the different ways SCSI drives can
be excluded:
/X0:1:2 This will exclude the drive on Host Adapter 0,
with target ID 1 and lun 2.
/X0:2 This will exclude the drive on Host Adapter 0,
with target ID 2 and ANY lun
/X0 This will exclude ALL drives on Host Adapter 0.
SAMPLE CONFIG.SYS
------------------
These samples assume that the user has loaded the Initio drivers
in the following directory: c:\ini910u.
Config.sys:
DEVICEHIGH=c:\ini910u\aspi910u
DEVICEHIGH=c:\ini910u\inicd.sys /R2
Explanation:
The first line loads the ASPI manager and the second line loads
the SCSI disk driver specifying that a minimum of two drive
letters be reserved for each MO and removable disk attached to
the SCSI bus.
How We Tested
=============
The INIDISK driver was tested for compatibility with cartridges
formatted using Microsoft Windows 95/NT, Adaptec AFDISK, and
Fujitsu FJFDISK v.2.03.
512 bytes/sec Cartridges:
-------------------------
The 512 bytes/sec cartridges of Fujitsu, Sony, and Hitachi MO
drives were formatted using Windows 95/NT, Adaptec AFDISK, and
Fujitsu FJFDISK. The formatted cartridges were partitioned with
single and multiple partitions. Adaptec AHA-2940U was used
during the partition and format of 512 bytes/sec cartridges.
Initio INI-9100U or INI-9090U was then used with Initio
INIDISK driver. The cartridges were tested for reading pre-
existing information and also writing new data. No errors were
encountered. INIDISK was tested to load concurrently with
Fujitsu MO driver and Adaptec ASPIDISK in CONFIG.SYS.
No errors were encountered.
AFDISK of Adaptec was used to partition cartridges controlled
by INIDISK and INI9100U.
1024 and 2048 bytes/sec:
------------------------
Adaptec AFDISK does not support any translations greater than
512 bytes/sec. Windows 95 and NT have built-in support for
greater than 512 bytes/sec MO cartridges. No need for a DOS
MO driver in CONFIG.SYS when using Windows 95.
Cartridges formatted with Windows 95 and NT were then used
with MS-DOS where INIDISK is controlling MO. No probelms
were found. In another test, the Fujitsu FJFDISK was used
to create multiple partition on a 640 MBytes 2048 bytes/sec
cartridge. The INIDISK driver was then used to read/write
to the cartridge without any errors.
Known Problems
--------------
Earlier today we saw some strange behavior that we are
still investigating. If you are using Windows 95 you don't
need INIDISK in CONFIG.SYS. However, in some systems, we
found that having INIDISK.SYS load in CONFIG.SYS under Windows
95 would cause the Miniport Driver to show a Yello Exclamation
mark under Device Manager. You may not see this problem. If
you do, please let us know. Once our analysis is concluded
we will correct the problem if it is related to INIDISK.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
