Paradise Video Adapters 10/06/92
PARADISE VIDEO ADAPTERS
-----------------------
Paradise EGA 480
This board is capable of higher, non-EGA resolution modes. Our drivers do
not support these modes. In order to install properly with this adapter,
set all dip switches to OFF, with the exception of switches number 2 and
3. The two switches that are causing the problems are switch #5 (auto
switch capability) and switch #6( monitor sense switch).
Paradise EGA and EGA 350
These boards are not known to have any problems installing and running
OS/2.
Paradise VGA+, VGA Pro and VGA 1024
These boards have problems installing OS/2. These are all 8/16 bit
boards, with an autosense switch used for detection of the bus width.
OS/2 will successfully install only if this capability is disabled. Set
the dip switch to OFF or insert the board into an 8 bit slot. After you
have successfully installed OS/2, you may put the board back into 16 bit
bus mode.
Paradise VGA Accelerator
This board is based on the WD90C30 and WD90C31 chipsets with 1MB of video
RAM and will have problems installing OS/2. After the first five
diskettes, error message C000005 appears during the reboot. An official
fix for BVHSVGA.DLL driver is available which will fix the problem. Call
the 800 tech support line and request to be mailed a fix for APAR PJ03721.
The fix is shipped with instructions on how to install the upgraded
driver.
There are a number of other video and motherboard manufacturers that are
using Western Digital/Paradise chipsets. 8/16 bit chipsets are PVGA1A and
PVGA1B, aka WD90C00. For boards built with these chipsets, apply the
autosense OFF fix for the successful i nstallation. Boards using WD90c30
and c31 experiencing the C000005 error should apply PJ03721 fix.
If you have installed successfully but experience video corruption
problems when switching back into a previously opened WIN-OS2 session, set
DOS parameter VIDEO_SWITCH_NOTIFICATION to ON in the DOS settings for the
WIN-OS2 session in question. You can reach the settings screen by
clicking with the right mouse button over the session icon and opening
Settings notebook, Session page. If there are synch problems on the
desktop with higher resolution adapters, check if the SVGA support has
been successful ly installed and activated. OS/2 installation detects if
the video adapter has higher-resolution capabilities and if so, specifies
SVGA basic video support in the CONFIG.SYS. This support is currently
limited to DOS session and VIO subsystem only. In orde r to activate the
support, SVGA ON command must be issued from a DOS full screen session and
the system should be shutdown after that. This will create a
configuration file called SVGADATA.PMI in the OS2 directory. If you are
not interested in the SVGA su pport, you may correct your CONFIG.SYS to
indicate VGA support only. CONFIG.SYS statements for SVGA support are:
SET VIO_VGA=DEVICE(BVHVGA, BVHSVGA)
DEVICE=x:\OS2\MDOS\VSVGA.SYS where x is your OS/2 system drive letter.
VGA support CONFIG.SYS statements are:
SET VIO_VGA=DEVICE(BVHVGA)
DEVICE=x:\OS2\MDOS\VVGA.SYS where x is your OS/2 system drive letter.
If after the PMI file is generated, some of the high resolution modes in
your DOS have video problems, you may consider regenerating the PMI file.
First remove the \OS2\SVGADATA.PMI file. Locate a DOS mode changing
utility that was shipped with the adapt er and run it in OS/2 DOS full
screen session. Select the desired video mode and exit the utility. Run
SVGA ON immediately after and reboot. This should ensure that timing
information in the PMI file is correct for your adapter.
General considerations
If desktop corruption exists and happens intermittently, run CHKDSK from
OS/2 prompt to detect if any harddisk corruption has taken place. If that
is so, run CHKDSK /F after you've booted OS/2 from A: and try to repair
the clusters. If you have DUAL bo ot installed, we recommend you install
MULTIBOOT (BOOT Manager) which protects OS/2 system files from corruption
caused by DOS low-level utilities. Running HPFS on a system with less
than 6 MB of RAM sometimes creates problems that seem to be of video nat
ure although they're not( blank screen, missing icons and similar). Check
if you are due for motherboard BIOS upgrade. AMI BIOS should be dated
5/9/91 and Phoenix BIOS should be dated 5/11/92 for reliable operation
under OS/2 v2.0. Also check if there is any memory address range or IO
port contention between your adapter and other adapters installed. In
some cases, disabling the VIDEO_BIOS_SHADOW_ENABLE function of the
motherboard BIOS also helps. Our PM desktop device driver supports only
640x480x16 mode (pure VGA). OS/2 shipped SVGA support is intended to
provide higher resolution modes for DOS and VIO (OS/2) applications only!
Please contact either Western Digital or your board manufacturer abo ut
the high-resolution PM display driver support. IBM is interested in
working with the video OEM on providing the high resolution support. You
may also install the 800x600 resolution PM DISPLAY.DLL that was shipped
with OS/2 1.3. Follow the instructions that came with that driver. If
you would like to obtain the driver, contact Paradise customer support.
You can obtain more information on OS/2 2.0 SVGA support from the README
file ( in INFORMATION folder).
If your DOS application is using a video mode which is not supported by
our DOS full screen drivers, you may install all DOS video related drivers
and mode utilities in OS/2 CONFIG.SYS and AUTOEXEC.BAT. You may also
specify DOS video driver DEVICE stateme nt in DOS_DEVICE setting in the
DOS SETTINGS for the desired DOS session.
