-
-
-
- Command line switches:
-
- whatvga [+acumos] [-ncr] [=1024]
-
- where +chipset forces WHATVGA to proceed as if this chipset was found.
- The test for this chip set will be executed in order
- to check for memory and revision.
- No other chipsets will be tested.
-
- -chipset ensures that the tests for this chipset will NOT be
- executed. Useful if a chipset is misidentified
- or some earlier test gives problems.
-
- =kbytes Forces the number of Kbytes of video RAM on the
- adapter to the specified value.
-
-
-
- Whatvga has 6 options in the main menu:
-
- 1 Test standard VGA
-
- Allows you to test the standard VGA video modes.
- Draws a test pattern, including a color palette
- and writes basic information as text on the display.
-
- 2 Test extended modes
-
- Allows you to test the extended video modes of the adapter.
- Draws a test pattern, including a color palette
- and writes basic information as text on the display.
- On the upper and left edge every hundred pixels is marked.
-
- 3 Scroll test
-
- Allows you to test the scroll function of the adapter.
- Draws a test pattern, including a color palette
- and writes basic information as text on the display.
- The test pattern is drawn in the largest resolution there
- is video memory for.
- With the arrow keys you can move around in the pattern.
-
- 4 Search for video modes
-
- Steps through the video modes 14h to 7Fh to see which ones
- are implemented by this adapter.
- When a video mode is found the rutine attemps to analyse
- the mode and then draws a test pattern to check the analysis.
- When the test pattern is displayed you can view the register
- values by pressing the "d" key, or save them to a file named
- REGISTER.VGA by pressing the "f" key.
-
- 5 Test VESA modes
-
- This item is only shown if a VESA driver is found.
- Draws a test pattern, including a color palette
- and writes basic information as text on the display.

- Acumos AVGA2:
-
- Scroll doesn't work.
-
-
- Avance Logic:
-
- Scroll has problems.
- Search for modes has problems with the width of scanlines
- and determining 256 or 64K colors.
-
-
- Cirrus 5422:
-
- Search for Mode has problems determing the number of bytes in a scanline.
-
-
- NCR:
-
- Search for modes has problems determining the number of bytes in a scanline
- in all 256 color modes.
-
- Oak:
- The 4 color modes (55h and 57h for the 067) currently doesn't work.
-
- Realtek:
-
- Mode 23h (1024x768 4color) does not work.
- Scroll has problems with crossing the 512K mark.
- Search for Mode has problems determing the number of bytes in a scanline
- VESA modes doesn't work.
-
-
- S3:
-
- The 86c924 is IDed as an 86c911A.
- I hear a rumor that they are actually the same ??
-
-
- Tseng 3000:
-
- The Tseng 3000 seems to enable different amounts of memory for
- different modes, thus using "larger than physical" displays
- is rather problematical.
-
-
- Generel Problems:
-
- I can't tell the difference between the Sierra "Mark2" SC11482/3/4
- (15 bits) and the "Mark3" SC11485/7/9 (15/16 bits) RAMDACs.
-
- The Acumos ADAC1 seems to be misidentified as an ATT20c491/2.
-
- With the SS24 DAC I can't tell if we are in an 256, 32768 or 16M color
- mode (Search for modes).
-
- On many cards interlaced modes are identified as app. half their
- actual height by the Search for modes rutine.
-
- Search for modes doesn't understand 2 and 4 color modes.
-
- Some of the extended modes may only be implemented on
- some otherwise similar boards, depending on make and BIOS rev.
