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.
