Hi, here there is a simple example to print image in Vga standard mode
16 color 4bit..
Bye

Thanks, but:

- It does not print, it tries to load it and display it on the screen only
- It is not a "standard" VGA mode, but a highly deprecated one 640*350,
for me it works in QEMU only, but not natively, 640*480 would be better
- It uses MMX without testing before, also there are no system requirements detectable
- "Interrupt MS-Kernel" is definitely a thing of the past

Then your graphics card is not VGA compatible, since mode 10h is a "native" EGA mode (for EGAs with 64k memory this mode is limited to 4 colors, however) and VGA comprises EGA.

Possible ... this mode is very old nevertheless ... even more
when considering the MMX code used

Does it work for you ?

> Does it work for you ?

Yes. (NVidea FX 5200)

ok, here there is a 640*480 simple example to display image to the screen in
Vga Standard mode 12h without MMX
minimal 386 cpu. Image file is formatted with index to the palette from 0 to 0fh , 16 colors 4bit.

Last example with 8086 code

I've heard that some newer video cards don't support EGA at all (don't ask me why)! It's SO annoying, IMO, when backwards compatibility is dropped because of the lame-o "we don't need it, no one uses it, it's old" crapola.

Even if your video card supports it, you also need a monitor that allows it, plus an OS that allows it (grrr, Vista supposedly borks on DOS gfx proggies, e.g. Hugi compo). Thank God for emulation (DOSBox, QEMU, BOCHS, etc).

EDIT: Just FYI, all three (DRAW, DISPLAY, 8086) work on my Win XP Home SP2 (P4) w/ ATI RAGE128 (VESA 2.0). However, under DOSBox 0.70 on the same cpu, all work except DRAW (MMX version). Funny that the 8086 version is 316 bytes (today is 3/16) but the MMX version is 286 bytes (but needs a Pentium w/ MMX). Oh, and it'd be nicer if you could specify the raw file via cmdline (really easy to implement).

COOL

Both examples do work on my EGA-incompatible card.

Add to "official" examples please



Thanks God for BOCHS and QEMU on DOS ... rest is for the Devil
