Daqarta for DOS Contents
When VGA fine adjustments are made, the new primary values become associated with that color number, not the screen item that uses that number. All screen items that use that same color number will thus appear in the same color.
If you attempt to make fine adjustments of the primaries and find that you only get a step size of 21 (and the color number changes as well), that means you are operating in EGA mode instead of VGA mode.
First, be sure that you really have a VGA graphics card in your system. If you are uncertain, check the connector on the back of the card: It should have 3 rows of pin holes. If it only has 2 rows, it is not a VGA card.
If there are two connectors, your monitor must be able to operate while plugged into the one with 3 rows of holes. Some older monitors allow switching between EGA and VGA by means of a switch marked "Analog / TTL"... it must be in the Analog position for VGA.
Another possibility, especially with an early VGA clone card, is that it doesn't support the IBM video detection standards properly. In that case, you can try forcing VGA mode by setting V:v on the INIT line of the DQA.CFG file. This will use the standard (slooowww) VGA BIOS function for palette changes. V:V invokes Daqarta's direct (default) method to eliminate flicker during palette changes, especially on slow systems. No guarantees here!
Note that if you have an EGA monitor connected to a VGA card (via the card's second connector, with two rows of holes), the card may still report your system as VGA. Daqarta will try to update the border or "overscan" area surrounding the main display to match the Panel color. Unfortunately, the EGA display timing isn't really fast enough to support this, so you will probably get a retrace streak near the bottom of the screen. Force EGA mode with V:e to eliminate the border.
color palettes to be optimized for other systems like monochrome laptops while working on a color system.
The GrayS option is crossed out on EGA systems.
If you are going to do a lot of this, consider setting V:E on the INIT line of the DQA.CFG file to force EGA mode.
Whenever a change is made to any color of a current palette, the palette is copied and given the name 'Work'. All further changes are to 'Work', leaving the original unchanged.
After the Work palette is created, it resides in memory with the other palettes, but with a "provisional" status. It is not lost when scrolling to another palette, and can be scrolled back to be modified, but it will be overwritten by modifying any other palette unless it is first saved to memory using the CTRL-PgUp Palette Operations submenu MEM option.
PALETTE to MEM:MEM replaces the current palette with the Work palette, if any, or allows renaming the current palette if not. If the current palette is Work, it will be converted into a regular palette with whatever name you choose.
You will be prompted for a name for the new palette, with the default being the current palette name. So if you want to replace that with the Work palette and keep the same name, you can just hit ENTER at the prompt.
Palette names are strictly for your own reference, and there is nothing to prevent duplicate names. Only the current palette can be replaced, and the prompt is just a way to allow you to rename it. Entering the name of another palette will NOT cause that palette to be replaced instead of the current one... you will just end up with duplicate names.
If the current palette is Work, you should enter a name that will be meaningful to you. Don't accept the 'Work' default name, or that will become its regular selection name. Then the next time you change any palette, another Work will be created that may confuse you.
Palette memory capacity is limited to 23 normal palettes and 13 spectrogram palettes beyond those loaded at startup.
You will not be allowed to delete the main Help palette, but you can always replace it. You will likewise not be able to delete the last regular palette in either main or Spectrogram modes.
Spectrogram palette memory to disk as a multi-palette file, after prompting for a file name. The default names are SGRAM.PAL and MAIN.PAL, or whatever files were loaded at startup on the third and fourth lines of the DQA.CFG file.
Note that during DDisk recording this option and the LOAD option will not be accessible to prevent drive access conflicts.
During DDisk recording this option and the FILE option will not be accessible to prevent drive access conflicts.
