It used to be the reason the VGA colors are wrong is because the AT&T 6300/Olivetti M24 swaps the low and high byte of 16-bit bus transfers -- the entire reason the bus correction kit was created, unfortunately. So some games send palette changes as words instead of bytes, and results in wrong colors on a 6300. But if you reboot without a network driver and that fixes it, I have no explanation. Because you can load and run software over a network, you may want to reconsider the CDROM drive. There is almost no reason, then and now, to have a CDROM drive in an 8086-class system.
I will have to try to run one of the device drivers that were provided with the buss correction kit to see if that may fix that particular issue. Possibly it may clear up the red screen on exit as well. The bad color pallet only seems to be affected by running Windows first, and honestly, rebooting the machine is not much of a hassle. Yeah, the CDROM is superfluous, but I still think it's kinda neat to see an optical drive in a machine it was never intended to be in. That, coupled with the sound card, makes it nearly a "multimedia PC" by early 90s definition.
Next put a battery in ? I just did on mine, batteries plus , 1/2 AA size, lithium-thionyl-chloride with axial leads. You can solder it in from the top side no problem.
As far as your issue, you don't have a V20 - you have a V30. Slightly different instruction sets, and more critically, different fingerprinting. If the code is checking for a V20, and doesn't see it, perhaps it quits? Something you should be able to check with SoftICE or another low level runtime debugger... Maybe make a patch? Pardon my 1995 Hollywood-derived parlance, but that would be pretty 'leet, homerow. And yes, I used 'homerow' back then, mostly to troll...
I was thinking that, but the fact that it does work correctly within DOSBox which would not announce itself as a V20, leads me to think that it only is concerned if 80186 instructions are present. I guess it deserves further evaluation.
Cool video, great seeing old computers still being used. Thanks.
This was a very cool video to watch, thank you for that. :D
Glad you enjoyed it!
