Just to be ultra-sure it's not the monitor (because it's really strict to what signal it expects , if something is out-of-specs then strange things happen lol ) http://i.imgur.com/eBP6B3El.jpg I dont think its your card or your monitor. The Video mode works, therefore both is OK. I think also the ( …

If you select a Windows 16 color driver it will never use more than 16 colors at once and will also not start to switch palettes! Imagine you have 2 Windows A +B on the Desktop and both uses a diffrent (16 out of 64) color set. Would be possible, but the colors in Window A would totally mess up …

We have already proven that VGA mode 12h works on your machine. Uhm, am I missing something ? :confused: That QBasic program should run just fine with any VGA-compatible card. As far as I know, both QBasic 1.1 and QB 4.5 do utilize the VGA BIOS. Well, at least QB should do (rarely use QBasic). If …

As expected wrong colors in the Logo ...But...registers and colors are VGA compatible :-p You're contradicting yourself. If the colors were VGA compatible, they wouldn't show up wrong. Try changing the colours in Windows. I wouldn't be surprised if nothing happens at all (the default palette for …

Frankly speaking...sorry but you do not seem to be familiar with this or never owned such EGA card ;-) Yes, there are many differences, but for this special mode it is the same. The VGA cards are downward compatible to all EGA modes. And the 640x480x16 mode is the same on VGA and (some, not all) …

Just because VGA also has a 640x480 16 colour mode doesn't mean the super-EGA cards are compatible with it. For starters, the VGA palette works entirely differently from EGA, so that's never going to work. Frankly speaking...sorry but you do not seem to be familiar with this or never owned such EGA …

And..what CPU do you have? Mine was 286. With a 386 you should try to disable EMM386 and Shadow options. I remember there is also a switch to force to run Windows in real mode (win /?). Maybe worth a try...

Hehe, yes in the Moment I also tried Win 3.1 Setup and also see there are some other 640x460 16 Color options (i.e. XGA). Did you try all of them? But as said, have no EGA at the moment. I also remember the wrong colors in the start logo with my EGA setup but with Windows itself all was OK.

This shows that yours cards are capable of this VGA mode...therefore it should work. Hmm I am sure it worked somehow without an extra driver...what selection do you have for the Video driver? Are there other 640x480x16 drivers to try? I have found this? http://www.basterfield.com/pc110/w31/w31-1. …

Not sure if you reallay require a new BIOS. I think the interrupt call was done by your card but your monitor was not able to display it. Just try some other values for the AL register: http://www.ctyme.com/intr/rb-0069.htm (Table 00010) Values for video mode: text/ text pixel pixel colors disply …

Hehe, no one confuses us with IBM :-) I am sure my card introduced as "Phoenix Enhanced Video Bios PLUS", maybe this is required for the feature.

I am almost sure that my EGA card (also with Chips Chipset) supported the standard VGA 640x480x16 (12h?) mode. So for Windows you just need a driver with that VGA resolution if this is also the case for your card. You can test with different other programs, select 640x480x16 VGA and see if there is …
