Hi,
I wanted to share another project of mine. This time, replacing the VGA ROM Fonts on a Tseng Labs ET4000 ISA card.
In short I wanted to replace the boring modernish ROM font on my card with custom ones made from a combination of old ATI fonts and my own touches.
I am spending quite some time in text-mode MS-DOS for programming reasons, thus I want to like what the screen shows me.
Read the whole thing here: http://www.alexandrugroza.ro/microelectronics … onts/index.html
The operation is not for the faint of heart as it involves removing the VGA ROM BIOS and its socket (if it's a low quality one). Then it involves reading the ROM contents, analysing it and then modifying it directly with specialised software (which I programmed on my own). But it is a fun project nonetheless.
Here are some pictures:
