+===============================================+
| DOS Driver for VG4 VL-Bus IDE Controller |
+===============================================+
Your VG4 disk controller needs the device drivers to take the advantage
of the high performance 32-bit VL-Bus when running under assorted
operating systems.
You can use the installation program "VG4.EXE" to install the DOS driver
and Windows driver automatically(Please refer to the VG4 Installation
Guide for details). If you want to install the drivers by yourself,
please follow the procedures below:
1. Complete the installation steps from (1) to (8) which are described
in the VG4 Installation Guide and boot to the DOS prompt.
2. Copy the driver VG4.SYS to your system in the appropriate path.
3. Add the following statement to your CONFIG.SYS file:
device=[drive:][\path\]VG4.SYS [/F] [/W] [/P] [/D0:n|/M0:m] [/D1:n|/M1:m]
where [drive:] and [\path\] point to the directory that contains the
VG4.SYS file. The parameters F, W and P define the operating mode,
and D0, D1, M0, M1, n, and m define the speed settings of the
attached hard drives.
F : VG4 controller works in the Fast mode(Default operation is
in Turbo mode).
W : VG4 controller works in the 16-bit data access mode.
Certain motherboard CPUs(for example, IBM 486 SLC2) have a
16-bit external data bus and cannot operate in the default
32-bit data access mode.
P : VG4 controller works in the Power-Saving-Detection mode.
This parameter is used when the IDE drive is not fully
compatible with the power saving functions.
D0 : drive 0 PIO speed setting
D1 : drive 1 PIO speed setting
n : drive speed from 0 to 8, or A
0 to 8 : PIO speed level(speed 8 is the so-called MODE 3
timing
A : IORDY indicator
M0 : drive 0 DMA speed setting
M1 : drive 1 DMA speed setting
m : drive speed from 0 to 8
0 to 8 : DMA speed level
In the Fast(F) mode, the VG4 disk controller supports 32-bit VL-Bus
I/O access. In the Turbo(T) mode, the VG4 not only supports 32-bit
VL-Bus I/O access but also read/write multiple commands. Since
read/write multiple commands allow the host to access disk data in
multiple-sector blocks, the Turbo mode will usually be faster.
Note that not all IDE drives support the read/write multiple
commands. Usually, you may set your VG4 to run in the Turbo mode.
When your system is brought up, the driver VG4.SYS will
automatically issue an Identify Drive command to check if the
attached IDE drive(s) support the read/write multiple commands.
In case your drive(s) does not support the read/write multiple
commands, the VG4 disk controll will automatically be forced to run
in the Fast mode.
Please also note: While some IDE drives may respond to the Identify
Drive command and confirm its capability to support the read/write
multiple commands, they may not support the read/write multiple
commands properly. In such cases, you will need to specify the
operating mode as "F" explicitly to ensure reliable operation of
such IDE drives.
Example:
The DOS driver VG4.SYS resides in the root directory of the drive C:.
If you want your VG4 controller to run in the TURBO mode; drive 0 at
speed 3 and drive 1 at speed 5. Please add the following statement
to the file CONFIG.SYS.
device = c:\VG4.SYS /D0:3 /D1:5
If your VG4 controller has to run in the Fast mode, the statement must
be changed to:
device = c:\VG4.SYS /f /D0:3 /D1:5
If the DOS driver is installed manually, you might have the following
three types of prompt messages when you boot up the system.
(a) HDD 0 setting: FAST Mode, Speed 5 by DEVICE DRIVER AUTOMATICALLY
HDD 1 setting: Turbo Mode, DMA Speed 5 by DEVICE DRIVER AUTOMATICALLY
Where the operating mode and the speed parameter may vary with the hard
drive(s) attached. This message will be shown when the device driver is
installed without any user specified parameter and the drive(s)
attached can be found in the internal speed table of the DOS driver.
(b) HDD 0 setting: FAST Mode, Speed 2 by HARDWARE JUMPER SETTING
HDD 1 setting: Turbo Mode, Speed 2 by HARDWARE JUMPER SETTING
+--------------------------------------------------+
| Notice |
| To optimize the performance of your HDD(s), |
| please execute the Installation Utility |
| to reconfigure your device driver |
+--------------------------------------------------+
Where the operating mode and speed parameter may vary with the hard
drive(s) attached. This message will be shown when the HDD(s) can't be
found in the internal speed table. It might appear when the drive(s)
are brand new models for the device driver, or the device driver is
copied from other PC's hard drive. The Installation Utility stands for
the VG4.EXE.
(c) HDD 0 setting: FAST Mode, Speed 5 by USER DEFINED SETTING
HDD 1 setting: Turbo Mode, Speed 5 by USER DEFINED SETTING
+------------------------------------------------------+
| Notice |
| Please ensure the above setting is your preference. |
| For better reliability and optimized performance |
| please execute the Installation Utility |
| to reconfigure your device driver |
+------------------------------------------------------+
Where the operating mode and speed parameter may vary with the hard
drive(s) attached. This message will be shown when user defined
parameter is entered with the DOS device driver. The Installation
Utility stands for the VG4.EXE.
[Note]
1. VG4.SYS support secondary IDE connector. You can connect up to four
IDE Hard disk Drives on your VG4 controller.
2. If there is a ROM BIOS on the VG4 controller, the VG4.SYS supports
LBA mode only on the VL/IDE (J1) connector and when it is set as
the primary controller.
3. If you would like to connect 3 (or 4) IDE hard disks, make sure the
DOS driver VG4.sys in installed. Than you can use the VG4FDISK.EXE
enclosed in the "Drivers and Installation Utilities" diskette to
partition you 3rd and 4th IDE drives drives before formatting
them.
+==========================================================+
| VG4 device driver for Microsoft Windows version 3.1 |
| and Windows for Workgroups 3.11 |
+==========================================================+
The file VG4.386 is the Microsoft Windows 3.1 disk driver for the VG4
disk controller.
While Microsoft Windows version 3.1 supports 32-bit disk access, the
disk data transfer between host and the IDE adapter is still limited
by the 16-bit ISA bus. If you want to speed up your hard drives under
Windows through the 32-bit VL-Bus, you need this driver. In addition,
the driver also allows your host to access the disk data through the
faster "read/write multiple" commands.
If you choose to install the Windows driver manually, you should
complete the installation steps from (1) to (8) which are described
in the VG4 Installation Guide, then follow the steps below:
1. Copy the driver VG4.386 to your system in the appropriate path.
It is recommended that the driver VG4.386 be copied to the Windows
SYSTEM directory.
2. Check if the following lines exist in the [386Enh] section of your
SYSTEM.ini file.
[386Enh]
32BitDiskAccess=ON
device=*int13
If the statements do not exist, add them into the [386Enh] section.
If the statements exist, but 32BitDiskAccess is set to "OFF", change
it to "ON".
3. Delete the "device=*wdctrl" device setting.
Delete the command line "device=*wdctrl" from the [386Enh] section
of your SYSTEM.INI file, if it exists.
4. Install the virtual device "VG4.386".
Add the following command lines in the [386Enh] section of the
SYSTEM.INI file:
device=[drive:][\path\]VG4.386
DisksAccessMode=[Fast|Turbo] [/W] [/D0:n|/M0:m] [/D1:n|/M1:m]
The [drive:] and [\path\] point to the directory that contains
VG4.386 file. Note that the setting must specify the full path
of the device driver VG4.386.
The setting of disk_access_mode specifies the disk access mode as
follows:
Fast : VG4 controller works in the Fast mode
Turbo : VG4 controller works in the Turbo mode(default mode)
W : VG4 controller works in the 16-bit data access mode.
Certain motherboard CPUs(for example, IBM 486 SLC2) have a
16-bit external data bus and cannot operate in the default
32-bit data access mode.
D0 : drive 0 PIO speed setting
D1 : drive 1 PIO speed setting
n : drive speed from 0 to 8, or A
0 to 8 : PIO speed level(speed 8 is the so-called MODE 3
timing
A : IORDY indicator
M0 : drive 0 DMA speed setting
M1 : drive 1 DMA speed setting
m : drive speed from 0 to 8
0 to 8 : DMA speed level
Note : If no parameter is specified, the VG4 disk controller will
be set to run under the default Turbo and 32 bit data access
mode.
In the Fast(F) mode, the VG4 disk controller supports 32-bit VL-Bus
I/O access. In the Turbo(T) mode, the VG4 not only supports 32-bit
VL-Bus I/O access but also read/write multiple commands. Since
read/write multiple commands allow the host to access disk data in
multiple-sector blocks, the Turbo mode will usually be faster.
Note that not all IDE drives support the read/write multiple
commands. Usually, you may set your VG4 to run in the Turbo mode.
When your system is brought up, the driver VG4.386 will
automatically issue an Identify Drive command to check if the
attached IDE drive(s) support the read/write multiple commands.
In case your drive(s) does not support the read/write multiple
commands, the VG4 disk controll will automatically be forced to run
in the Fast mode.
Please also note: While some IDE drives may respond to the Identify
Drive command and confirm its capability to support the read/write
multiple commands, they may not support the read/write multiple
commands properly. In such cases, you will need to specify the
operating mode as "Fast" explicitly to ensure reliable operation of
such IDE drives.
[Note]
1. If there is a ROM BIOS on the VG-4 controller, the VG4.386 supports
LBA mode only on the VL/IDE (J1) connector and when it is set as
the primary controller.
+========================================================+
| Netware 3.xx & 4.01 disk driver for VG4 Controller |
+========================================================+
It's assumed that you are familiar with Netware installation. If this
is not the case, please refer to related documents.
Please follow the steps below to install the driver for Netware 3.10,
and use VG4311.DSK(VG4401.DSK) instead of VG4310.DSK in the following
procedure when you are installing Netware 3.11, 3.12 or 4.01. Note that
you don't have to load the ISADISK.DSK when you are installing the
Netware driver for VG4 disk controller.
1. After you have installed the VG4 disk controller, bring up the
Netware server until the prompt ":" appears on the screen.
2. Type the following command after the ":" prompt:
:load VG4310 [/F|/T] [/W] [/D0:n] [/D1:m] port=1f0 int=e
The parameters F, T and W define the operating mode. The parameters
D0, n, D1 and m define the speed setting for the attached IDE
drives.
F : VG4 controller works in the Fast mode(Default operation is in
Turbo mode).
W : VG4 controller works in the 16-bit data access mode.
Certain motherboard CPUs(for example, IBM 486 SLC2) have a
16-bit external data bus and cannot operate in the default
32-bit data access mode.
D0 : drive 0 speed setting
n : drive 0 speed from 0 to 7
D1 : drive 1 speed setting
m : drive 1 speed from 0 to 7
Usually, you do not need to enter any speed parameters during the
installation process. Since when you execute the VG4.EXE to install
the DOS driver, the device drivers for Netware are also reconfigured
for the optimal speed setting.
Note: If no operating mode parameter is specified, the VG4
controller will be set to run in the default Turbo and 32 bit
data access mode.
In the Fast(F) mode, the VG4 disk controller supports 32-bit VL-Bus
I/O access. In the Turbo(T) mode, the VG4 not only supports 32-bit
VL-Bus I/O access but also read/write multiple commands. Since
read/write multiple commands allow the host to access disk data in
multiple-sector blocks, the Turbo mode will usually be faster.
Note that not all IDE drives support the read/write multiple
commands. Usually, you may set your VG4 to run in the Turbo mode.
When your system is brought up, the driver VG4xxx.DSK will
automatically issue an Identify Drive command to check if the
attached IDE drive(s) support the read/write multiple commands. In
case your drive(s) does not support the read/write multiple
commands, the VG4 disk controll will automatically be forced to run
in the Fast mode.
Please also note: While some IDE drives may respond to the Identify
Drive command and confirm its capability to support the read/write
multiple commands, they may not support the read/write multiple
commands properly. In such cases, you will need to specify the
operating mode as "F" explicitly to ensure reliable operation of
such IDE drives.
