- BACKGROUND
- ══════════════
-
- The Digital Tours Access System (software interface) employs
- SOSVIEW.EXE as the graphic file viewer. Even though
- SOSVIEW.EXE has a reputation for being easy to use and
- trouble-free, occasionally you may experience difficulties.
- This error list reference is provided to assist you in
- diagnosis of many possible problems and their solutions.

- Selecting Video Drivers Using PICKDRVR.EXE
-
- Video drivers for the correct video card MUST be installed to
- operate the program correctly. For convenience, use
- PICKDRVR.EXE to install the drivers from a menu-driven
- utility. If a driver is listed which directly supports your
- [PAGE DOWN FOR MORE]
-
- video card, select that driver from the PICKDRVR.EXE list. If
- no direct support video driver is listed and your video card
- is VESA compatible, select the VESA driver from the
- PICKDRVR.EXE list. If you are uncertain which video card is
- present in your computer, consult your system manual, or
- package of manuals which you received with your computer.
-
- < SPECIAL NOTE > Most newer video cards are now VESA Compatible
- SVGA. Many of these cards are BIOS compatible, which means
- that the cards can autodetect (recognize) VESA compatible
- "calls" without any additional user modifications. Some older
- cards may require loading an additional software driver to
- force the video card into VESA mode. These software drivers
- and the necessary instructions should be found with the
- manual and disk which came with your video card or computer.

-
- ERROR: CANNOT FIND GRAPHIC MODE FOR THIS IMAGE
-
- A. Video drivers for the correct video card MUST be installed
- to operate the program correctly. For convenience, use
- PICKDRVR.EXE to install the drivers from a menu-driven
- utility.
-
- B. Video card may not have enough video RAM. Most of the
- useful SVGA video modes require at least 512K video RAM.
-
- Note: 512k video RAM required to view images 640x480x256
- 1 Mb video RAM required to view images 1024x768x256

- ERROR: (No error message will report)
-
- If you are using a DOS shell such as Windows, XTREE,
- 1DIRPLUS, or DesqView, you may want to leave the shell and
- return to DOS. SOSVIEW routines are well behaved, but, any
- co-existing shell or TSR usage runs the risks of excessive
- memory allocation or internal contention that could lock up
- the PC. SOSVIEW routines do direct screen writes which may
- cause contention with ill-behaved TSRs. When SOSVIEW
- routines give you error messages relating to OUT OF MEMORY or
- inability to allocate memory for buffers, the shell or
- terminate-and-stay-resident utilities are hogging precious
- RAM and preventing from correct operation. Well-known ill-
- behaved TSRs like SIDEKICK are definitely at risk for
- crashing when attempting to co-exist with database
- applications. Microsoft WINDOWS 2.11 or older will NOT work
- with SOSVIEW routines. All versions of DESQview, including
- DV/X are known to not correctly restore or refresh SuperVGA
- graphic mode screens upon returning to a graphic process
- [PAGE DOWN FOR MORE]
-
- (after swapping to another process). This is a DESQview
- problem and occurs even with DESQview-specific or DESQview-
- aware programs running in SVGA graphics modes. Unless your
- graphic mode application can refresh its own graphics screen,
- there is no currently known solution. The graphic mode
- process works correctly except for this problem and only when
- swapped out. It does not crash. Quarterdeck Systems is
- working on this problem.

- ERROR: (No error message will report)
-
- MONITORS: 800x600 at higher require analog, multisync/or
- analog fixed frequency Monitors that support the desired
- video modes. Incorrect display, rolling of picture, jumbled
- image, distortion and severe monitor damage may result from
- over-driving monitor. Even though monitor may appear to
- support the desired modes, some video cards can easily over
- drive inexpensive monitors, even those claiming to support
- the desired modes, because they are high performance and
- [PAGE DOWN FOR MORE]
-
- require greater bandwidth than monitor can support (C&T 453
- chipsets, etc) Some SVGA cards have dip-switches or jumpers
- to "throttle back" or reduce the bandwidth to fit
- capabilities of inexpensive monitors. This is a different
- parameter than the 8-bit/16-bit mode of operation jumpers.
