- Using Optiks SYS files.
-
- OPTIKS can create a device driver which displays a graphic screen
- and keeps it up during the DOS boot. The device driver will intercept
- all video i/o until a program named FBLOT.COM is run.
-
- OPTIKS makes conversions from one format to another by reading in
- graphic files into its workspace and then saving them as other formats.
- To create a SYS file, load in a graphic and save it using the
- SYS selection. When OPTIKS asks for a range, only indicate a screen's
- worth of graphics. The sys file will only display one screen.
-
- A device driver created by optiks should be tested off of a floppy
- diskette first. Format a floppy with the /S option and copy the
- device driver to the floppy. Also copy the fblot.com program to the
- floppy.
-
- Create a config.sys file and have the statememt:
- DEVICE=XXX.SYS
- where xxx.sys is the name of the sys file created by optiks.
-
- Create an autoexec.bat file that has the command FBLOT in it.
- You may want to have the PAUSE command execute before fblot so that
- you can wait to look at the graphic.
-
- Boot off of the floppy. If the graphic does not appear or the
- machine hangs up, then there is something wrong. DO NOT TEST A
- SYS FILE ON A HARD DISK. If there is a problem then you will have
- to boot off of a floppy to fix the problem.
-
- I have tested the sys files created by OPTIKS. As long as they are
- under 64K they seem to work fine on all of the machines I have.
- ANSI.SYS does not conflict with the sys files, but other types of
- enhanced ansi type programs may have conflicts. Put the OPTIKS
- sys files in the config.sys as early as possible.
