can you change adress port or disable onboard game port from bios?

Memory is a big issue under DOS , you need aditional memory manangment apps to load , try EMM286 ... worked sort of for me on my 80286 Toshiba.... You may also need to test the memory for problems (sometimes hard to diagnose).
It may also be that EGA value's loads into memory already used , you can check your memory allocation under NC(northon commander).... It's a jurney but it's doable.

Win95 manages difrently I think , so you may try loading win , than start -reboot under command.com and load game , may work better.

Unfortunately, there isn't actually a Game Port on the motherboard, so the bios has no settings that I can see that will help with that. I don't know if there is a version of the bios that would have that option (or how to change it)

This is the board that I have:
https://theretroweb.com/motherboards/s/dec-ve … 86-433-ver.-2.0

The computer has 36mb of ram and the onboard video has 1mb. I have my DOS boot with an option to boot with extended, expanded or no memory manager.
I have played around with Norton Utilities but never saw it report an error. Is there a particular test I should do?
Is it the video memory or the main memory that would be the issue here?

Just to clarify, with win95, it is just the EGA issue that works. The non existent game port still acts up.

Onboard GPU is adressed in main memory (this if ram dimms are fine and not with problems) , NC is for checking allocation of EGA , and conflicts manually , for Ram check you can do CheckIT from dos or
check manually like adrian on YouTube

I haven't downloaded CheckIt yet, but I have been playing around with Norton. (I have an original CD with all the tools on it.)

I found a memory test, booted in with and without memory managers and tested all the memory I could find tests for. Including the video memory.
It found no errors. The video tests had no errors, but the mode tests, it skipped one of the mode tests.

Other things that I found was that in one boot, Norton detects that there is a joystick and in a different boot (one with mem managers, on without) id doesn't find it. Although a separate joycheck program always sees it.
There is also a IRQ check and Norton will list everything on the IRQs, or if it is not used. On this check every time, IRQ 2 is present but unknown.

I saw the video. I hope I don't need to resort to that. The Norton test was testing the stuck bits in the ram...

I'll get Checkit when I get home and run that test.

I ended up needing the XTIDE bios & CF card reader in a different computer, and I came back to this one recently and just put in an IDE HDD to get it going.

The game port problem is just gone. I assume that it must have been conflicting the the XTIDE bios somehow...
