Hello, what's happening fellow retro gamers, hope you are doing ok. So I have been setting up a DOS 6.22 Rig. Here are the specs
Motherboard:LS-486E Rev:D
Graphics card: SiS 6326 4MB
CPU: Am5x86-P75-S
Soundcard: Soundblaster pro 2.0
32 MB of Ram

Not really the best 486 but it has not really disappointed me. However, the reason I am here is I am having 2 issues, 1 the turbo button locks it up anytime it is pressed(I will post this issue in hardware) but the main thing is whenever I try and play Duke3D from my authentic cd-rom I am thrown this error message (see picture attached) I have been trying every troubleshooting step I can think about and I am not progressing at all. The only time I've been able to get it to work on this PC is if I install windows 95, I'm wanting to have more of a strictly DOS build because I have a windows 98 P3 Machine. Any help or advice would be greatly appreciated
