EVAfont driver
EVAfont driver is a font file format associated with EVAfont, a screen font editor for DOS. EVAfont was developed by Pete I. Kvitek.
A driver is an executable file, in COM format. It can be executed independently, to load the font (and presumably keep it loaded).

Format details
The template used by a driver file depends on the version of EVAfont, and the font size. Three versions of EVAfont have been found, and there's good evidence of at least one more. And there are three possible font sizes: 8x8, 8x14, and 8x16 (though v2.01 does not seem to support 8x8 drivers).
Identification
Every driver for a given {version + font size} is probably very formulaic, but there's no obvious signature that would identify all formats at once.
All known formats start with byte 0xe9.
For v2.01, the text "text font loader" appears at offset 7, as part of a longer string starting at offset 3.
For v3.05i and 3.05, "font driver" appears at offset 8, as part of a longer string starting at offset 3.
Files made by v2.01 contain the string "v2.01A". Those made by v3.05i contain "v3.04a". Those made by v3.05 contain "v3.05c". An unknown "v2.04A" version apparently exists.
