2.0 Configuration
==================
2.1 Hardware Installation
--------------------------
Setup and Install your DTC IDE controller per the instructions provided
in the Install Guide shipped with your specific card.
2.2 "EZIDE" Install Utility
------------------------------
DTC provides a utility to automatically install the DOS and Windows
device drivers into your Hard Disk Drive. This utility will copy all
necessary files and update your CONFIG.SYS and SYSTEM.INI files.
This utility requires that the C: drive has been Partitioned (DOS FDISK)
and Formatted (DOS FORMAT).
To use EZIDE, insert the DTC Enhanced IDE driver diskette in the
A: drive and type:
A:EZIDE <CR>
Follow the on screen instructions, the EZIDE utility will walk you
through the installation.
2.3 Software Device Drivers
----------------------------
The DTC Enhanced IDE Drivers will automatically configure the drives and
the DTC IDE card for maximum performance/features.
The DTC 2278VL does not allow automatic programming of the IDE transfer
rate. You will need to set the IDE transfer rate with the jumpers
provided on the card.
A set of Software switches have been included to:
1) Aid in debug
2) Work around HDDs that may not conform exactly to the ATA 3.0 and
ATA-2 Specifications, or
3) Work around bugs that may exist in a HDD. Refer to Software
Switches section for definition and use.
3.0 Installing Enhanced Device Drivers
=========================================
3.1 DOS
--------
The DOS driver, DOSEIDE.SYS, needs to be loaded to support the
Secondary Port , turn on 32-bit mode, enable multi-sector transfers, and
program the DTC IDE card and each IDE device for optimal performance.
* Insert MS-DOS boot disk in drive A: and reboot system.
* Partition the IDE drive with DOS FDISK and then perform DOS
FORMAT. Install DOS on the hard drive.
* Copy the DOSEIDE.SYS file to the root directory of the boot
drive.
* Add the following statement to the CONFIG.SYS file:
device=DOSEIDE.SYS
* To ENABLE the Secondary port/card modify the CONFIG.SYS file by
adding a "/2" to the driver lines as follows:
device=DOSEIDE.SYS /2
* Re-boot the system.
3.2 Windows 3.1x and Windows for Work Groups 3.11
--------------------------------------------------
All 32-bit DTC IDE controllers support 32-Bit Disk Access and 32-Bit
file access under Windows 3.11. The DTC Windows driver, WINEIDE.386, is
a Virtual Mode Driver (VxD) that can be used in place of WDCTRL.
* IT IS RECOMMENDED TO FIRST VERIFY THAT YOUR SYSTEM AND HARD DRIVE IS
* COMPATIBLE WITH THE 32-BIT DISK ACCESS FUNCTIONS UNDER WINDOWS USING
* THE BUILT-IN WDCTRL DRIVER. IF YOU HAVE BEEN SUCCESSFUL USING THE
* WDCTRL DRIVER, THEN PROCEED WITH THE INSTALLATION OF THE DTC WINDOWS
* DRIVER - WINEIDE.386
The WINEIDE.386 driver provides the same functions, but also includes
32-bit PIO transfers to the DTC IDE card, supports multi-sector
transfers, and programs the DTC IDE card and each IDE device for optimal
performance.
* Copy the WINEIDE.386 file from the DTC Driver diskette into
the C:\WINDOWS\SYSTEM directory.
* Edit the file SYSTEM.INI located in the C:\WINDOWS directory.
Locate the [386Enh] section. If "32BitDiskAccess" is already
enabled (=on), you must disable the WDCTRL Driver by placing a
semi-colon (;) at the beginning of the line. Then add the
WINEIDE.386 driver line as follows:
32BitDiskAccess=on
device=*int13
;device=*wdctrl
device=wineide.386
If "32BitDiskAccess" is not enabled (=off), then add the
following lines to the beginning of the [386Enh] section:
32BitDiskAccess=on
device=*int13
device=wineide.386
3.3 IBM OS2 V2.x
-----------------
NOTE - FOR IDE HARD DRIVES WITH > 1024 CYLINDERS
If you choose to use the standard FAT for your primary partition
(< 512 MBytes), you will need to create a small secondary HPFS
partition to operate properly under OS/2.
If you choose to use HPFS for your primary partition then no
additional partition is necessary.
3.3.1 Installation, where OS/2 was previously installed
--------------------------------------------------------
* Boot OS2 * Copy the DTCIDE.ADD file from the DTC Driver diskette to
the /OS2 directory on the bootable hard disk.
* Edit the CONFIG.SYS file in the root directory:
1. Remark out the current driver as follows:
REM BASEDEV=1BM1S506.ADD
2. Add the DTC Enhanced IDE device driver statement.
BASEDEV=DTCIDE.ADD [Software Switches]
* Reboot the System.
3.3.2 New Installation
-----------------------
* Create a DTC Installation Diskette DTC D1 as follows:
1. Backup original OS2 Diskette 1 to new diskette DTC D1.
2. Edit the CONFIG.SYS file on the DTC D1 diskette.
REM BASEDEV=1BM1S506.ADD
BASEDEV=DTCIDE.ADD [Software Switches]
3. Delete the IBM1S506.ADD file from DTC D1.
4. Copy DTCIDE.ADD file from the DTC Driver diskette to
the DTC D1 diskette.
* Install OS2 according to the OS2 installation guide. When
Diskette 1 is prompted, insert the DTC D1 diskette.
#NOTE#
Any Software switches entered must be the same as the DOS Software
switches, in a dual boot configuration.
3.4 Novell NetWare
-------------------
3.4.1 NetWare 386 V3.1, V3.11, & V3.12
---------------------------------------
* Copy the file dtcide3.dsk from the DTC driver diskette to the
directory where the Novell "server" is installed.
* At the NetWare console prompt (:) type:
LOAD DTCIDE3 [Software Switches]
#NOTES#
1. For a Dual Port configuration, load the DTCIDE3 driver twice. Once
for each port, or add a "/2" Software Switch to the load line.
2. Any Software switches entered must be the same as the DOS Software
switches.
3.4.2 NetWare 486 V4.0
-----------------------
* Copy the files dtcide4.dsk and dtcide4.ddi from the DTC driver
diskette to the directory where the Novell "server" is
installed.
* At the NetWare console prompt (:) type:
LOAD DTCIDE4 [Software Switches]
#NOTES#
1. For a Dual Port configuration, load the DTCIDE4 driver twice. Once
for each port.
2. Any Software switches entered must be the same as the DOS Software
switches.
3.5 Windows NT
---------------
* Install the Windows NT Operating System. Follow the
instructions provided with the OS, using the built in IDE
Driver, ATDISK
DO NOT use the DTC ATDISK.SYS driver to replace the original
ATDISK.SYS in the original NT Boot Disk.
* After completion of installation:
1. Locate the Drivers Directory . At the prompt, type:
CD C:\WINNT\SYSTEM32\DRIVERS
2. Backup existing IDE driver. At the prompt, type:
COPY ATDISK.SYS ATDISK.ORG
3. Insert the DTC Driver Diskette in Drive A:. Copy the DTC
Windows NT driver to the C: Drive. At the prompt type:
COPY A:ATDISK.SYS C:\WINNT\SYSTEM32\DRIVERS
5. Reboot the system by Shutting Down and Restarting.
3.5.1 DTC Windows NT Driver Configurable Parameters
----------------------------------------------------
Windows NT contains a Registration Database called REGISTRY. During
Initialization/Configuration Device drivers can use the Registry
Database to get Parameters. Typically the creation of the Registry
Database is NOT required. The DTC Windows NT driver will auto
configure itself and the attached HDDs for the maximum performance.
The Configurable Parameters are used to resolve problems that may
occur with specific HDDs. The default values are highlighted.
Modifying/Creating Registry Database
* Open a working window. At the prompt, type:
REGEDT32
The DTC Window NT driver's parameters will be located under
the following tree string:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atdisk

5.0 Dual Port Issues
=====================
There are several issues that you will need to be aware of when using
a dual port configuration.
1. The secondary port uses IO addresses 170H - 177H & 376H and IRQ15 for
operation. The secondary port still uses the Master/Slave convention of
identifying and accessing the drives. You do NOT have to set the CMOS
for any HDDs on the secondary port.
2. After installing a Dual Port Configuration, you then go back and
add another partition or a drive. In this situation the Drive Letter
assignments will be changed the next time you reboot. You must under-
stand the drive assignments before using the DOS FORMAT command to avoid
formatting the wrong drive. Review the following example.
Example:
Initial DOS Drive Letter assignment Adding Partition with DOS FDISK
Primary Master 500MB
Single Partition 250MB C: First Partition 250MB C:
unused disk space 250MB Second Partition 250MB G: !!!!
Primary Slave 210MB
Single Partition 210MB D: Single Partition 210MB D:
Secondary Master 1.2GB
First Partition 500MB E: First Partition 500MB E:
Second Partition 700MB F: Second Partition 700MB F:
After Reboot DOS will assign the Drive Letters as follows:
Primary Master 500MB
Single Partition 250MB C:
Second Partition 250MB E: (G:)
Primary Slave 210MB
Single Partition 210MB D:
Secondary Master 1.2GB
First Partition 500MB F: (E:)
Second Partition 700MB G: (F:)
3. The Secondary Port Drive Letters are assigned differently than the
Primary Port.
The Primary Port drives are assigned in the following sequence:
1. Primary Master is Drive C:
2. Primary Slave (if present) is Drive D:
3. Primary Master Logical drives are assigned starting at the next
available drive letter. (either D: or E:)
4. Primary Slave Logical drives are assigned starting at the next
available drive letter.
The Secondary Port drives are assigned in the following sequence:
1. Secondary Master drive is assigned to next available drive letter.
2. Secondary Master Logical drives are assigned in order.
3. Secondary Slave drive is assigned to next available drive letter.
4. Secondary Slave Logical drives are assigned in order.
4. It is recommended that IDE CD-ROMs be installed on a secondary port.
This will allow you to Enable 32 bit disk access in windows (using
WINEIDE.386 or WDCTRL.386 drivers). The "/2" switch must be invoked,
even if the CD-ROM is the only drive on the secondary port.
6.0 Troubleshooting
====================
This section lists some of the problems the user might encounter
following installation and configuration of a DTC IDE card.
For additional troubleshooting information, refer to the Install Guide
that you received with your DTC IDE card. It will contain information
that may be specific or unique to your card.
PROBLEM: The DTC IDE card Hangs or Fails when you access the Hard Disk.
SOLUTION:
1. Verify that the CMOS settings are correct for the drives attached.
2. Check that the drive has been Partitioned (FDISK) and DOS formatted.
3. If a PCI/IDE card, verify that you have properly redirected the
Primary Port interrupt to IRQ14, and the Secondary Port interrupt to
IRQ15.
4. The information obtained from the drive about its operational
capability, may be incorrect. Use the Software switches to put the
drive in a standard operation mode.
Step 1: Determine if Multi-Sector is the problem by
disabling Multi-Sector transfer. /dx:m0
Step 2: Determine if Drive Transfer rate is the
problem by setting drive to standard PIO Mode 0. /dx:p0
If you have a DTC 2278VL set the IDE transfer rate to 3.3 MB/s.
PROBLEM: The DTC IDE card will not run Windows 3.1 or WFWG 3.11 in
the Enhanced Mode.
SOLUTION: The DTC IDE card does support WFWG 3.11 and Windows 3.1
in Enhanced mode. Check the following:
1. Make sure you have installed the latest DTC Windows Driver
WINEIDE.386 in the SYSTEM.INI file correctly. See DTC Windows
driver installation instructions.
PROBLEM: Can not access Secondary Port drives.
SOLUTION:
1. Check that the /2 switch is included on the driver line.
2. If a PCI/IDE card, verify that you have properly redirected the
Secondary Port interrupt to IRQ15.
3. Check that the drives have been partitioned (FDISK) and DOS
formatted.
4. In Windows Enhanced mode (32BitDiskAccess=on), then the WINEIDE.386
driver must be loaded. In addition the DOSEIDE.SYS driver must be in-
stalled.
PROBLEM: Performance is not up to expectation. Data transfer
rates appear slow.
SOLUTION:
1) Verify that the DOS device driver, DOSEIDE.SYS, is installed.
2) Use an IDE hard drive that supports multi-sector transfers and has
a fast data transfer rate as reported by the drive manufacturer.
New drives that support the ATA-2 Specification show the best results.
3) Some benchmark programs do not properly measure data transfer rates
and therefore show no improvements. Use DTCSPEED.EXE included on this
disk or CoreTest which is available on the DTC BBS.

8.0 "DTCSPEED" benchmark utility
=================================
DTCSPEED is a simple hard disk benchmarking program which measures
data transfer rate between the drive and the host. The results are
displayed in KBytes/Sec.
When DTCSPEED is run, it will display 2 columns of information.
The first column, **Read**, displays the results of reading:
(Measures the maximum transfer rate from a cache hit)
1) a fixed 16 KByte block of data repeatedly.
2) a fixed 64 KByte block of data repeatedly.
The second column, **SeqRead**, displays the results of reading:
(Measures a mix of the drive's head data rate (Cache miss), track
switching and the drive's read ahead capability)
1) sequentially 16 KByte blocks of data.
2) sequentially 64 KByte blocks of data.
Typically the results from the second column will be lower than the
first column.
Typically you will see an increase in performance when you have the
DTC Driver loaded versus when it is not loaded.
If you do NOT see an increase in performance when you have the DTC
driver loaded, it could be because:
* the drive does NOT support multiple sector per transfer
* the drive is slow. Find out how fast the drive is rated
(contact drive manufacturer or use the /v option on the
DOS driver line)
