- Frequently encountered Problems with Skullitaire.
-
- Q: What does "Err4F: No VESA support" mean?
- A: This program uses High Resolution-graphics in 640 by 480 Pixels and
- 256 Colors.
- To use this resolution, you must map more than 64K of video memory
- and first of all SET this graphics mode.
- Unfortunately there are as many methods to set the video mode as there
- are VGA-Cards.
- Fortunately the manufactorers knew about this...
- ...and set up a standard of accessing the extended possibilities of a
- video card - the VESA-Standard.
- Unfortunately -again- the standard came late, so most of the cards don't
- support this standard, but some do...
- Fortunately -yeah-: For almost all VGA-Cards there is a Software-VESA-
- Driver available; I supply a universal VESA-Driver (Shareware!) named
- "univesa.exe" in the same directory as Skullitaire.
- For those of you guys, who don't have a VESA-Driver implemented in the
- BIOS, you must load a VESA-Driver manually.
- This Error message above means that there is actually no VESA Driver
- loaded, so the program can't start!
-
- Q: I get a "Not enough memory" Error. Why?
- A: There are several different types of memory. You machine may have 2, 4,
- 8, 16 or more Megabytes of memory but Skullitaire can't use it!
- Skullitaire only needs memory that's called low DOS memory, or conventional
- memory, which is the memory portion below 1Meg!
- DOS can only use 640KBytes of memory, and that's what Skullitaire can use!
- You can check your memory by typing either CHKDSK (DOS before v4.0) or
- MEM (DOS v4.0 or higher). To run Skullitaire you must have at least
- 540KBytes of free memory.
- If you don't have this much, you get the above Error message.
-
- Q: I get a "Low memory warning". What shall I do?
- A: This means you have enough memory to run Skullitaire, but Skullitaire MAY
- run instable! Instable means, the program may break with a Runtime error
- message, or even crash.
- Instability, though, is fairly seldom... so don't panic!

-
- Q: I have enough RAM, SVGA and all but Skullitaire still refuses to run
- correctly. Why?
- A: Skullitaire uses the Microsoft mouse drivers. You should try to run
- your mouse in Microsoft mode (By reinstalling the mouse or using the
- setup utilities for your mouse, etc.). In a lot of cases this was the
- solution to the most problems we encountered on other machines.
- (Some "encounters": Skullitaire crashed even before showing the title.
- The mouse pointer scrambled the background. The mouse pointer did not
- move at all...)
-
-
- Q: I get a "SoundBlaster environment" Error. Why?
- A: Skullitaire has detected a Soundblaster but couldn't utilize it, because
- the Environmet wasn't set. You usually add a line to your autoexec.bat
- which says:
- SET BLASTER=A2X0 IX DX TX
- ^ ^ ^ ^
- | | | +--- Type of Soundblaster 1: normal, 2: pro etc..
- | | +------ The DMA-Channel (DMACH). usually 1
- | +--------- The IRQ-setting. Usually 5 or 7
- +-------------- The Base adress. Usually 220, seldom 240
- where the "X"s are individual for your configuration.
- Make sure that this line is correctly set!
-
- Q: I use a Soundblaster but the Sound isn't played correctly, the sound
- is played half and then breaks!
- A: Your IRQ-setting in the environment isn't correct! (see above)
-
- Q: "My screen breaks up, and the animations seem to be played incorrectly!"
- A: This is a frequent problem on Machines with a AcuMOS or newer Cirrus-Logic
- Chipset. (These Cards have a ROM-resident VESA-Driver).
- They don't handle the VESA-implementation correctly, they have a VESA
- v1.1-Implementation, which MAY cause problems. Try using the UNIVESA-
- Driver. On Acumos Chipsets, the Screen may look broken up and moved over
- the Screen-Edges. This is due to the VGA-internal Page-switch algorithem:
- High Resolutions require more than 64KBytes of memory, but the VGA-Card
- can (and must) only map 64K at a time. So you must "switch video pages".
- This means you move a window over the entire video-memory.
- This window can be moved either in 4K, 16K and (most common:) 64K-steps.
- Acumos cards support the steps of 4K and 64K. Standard is 4K. Sometimes,
- though, the card is switched into 64K-"granularity", but the BIOS isn't
- informed about that... So the steps, thought to be 4K, are now 64K in
- size. If you switch Pages, the memory is remapped in far to big steps,
- and you get whats called a "wrap-around": The video memory has been re-
- mapped to a memory location in video memory, that the card doesn't have...
- So the cards starts to map at the beginning of the memory again and you
- write into a memory-location, you don't wan't to write to - and you don't
- even know about it!
- The only practicable solution to this problem is, to restart your
- computer...
