Are you certain it is a hardcoded requirement and not just a setting which depends on the CD drive letter it was installed from? I tried this copy of Worms CD just now (not sure which version), and the CD drive letter is encoded in SETUP.CFG offset 12 (0xC) as a 1-based integer value of the letter. …

You can get around this but it is a bit dumb. Create two partitions, 1 that is a scratch disk, say 10MB (D:), and the second is everything else (E:). In Autoexec.bat do this: LOADHIGH C:\DRIVERS\SHSUCDX.COM /D:IDE-CD /L:F /V /C LOADHIGH ASSIGN D:=F: This will assign your CD to F: and then "Assign" …

So I'm setting up a brand new partition on MSDOS and as I already have a primary partition, I have to create an extended one and then a logical one, but for some reason it's giving me the letter D: as the hard drive, instead of E: The problem is that WORMS game (version 1.0) requires CDROM drive to …

I was wondering why the heck when we're using 256 colors mode in Windows 95 or 98, sometimes the screen refreshes with wrong color palette and then if you open another window / close a program, all of sudden it goes back to normal? I notice this behavior since my first PC back in the 90s but never …

How does that mode look like? I would expect some garbage, or a completely different mode from the one it's trying to set. Anyway, it's possible that SVM doesn't attempt to detect the RAMDAC type, and/or it's a version for different card. By the 'preview mode' from the SVM.EXE, it looks the same as …

Grzyb wrote on 2024-01-23, 16:01: KDA0476 is a standard VGA RAMDAC, limited to 256 colors. I see, so this is the best we can get. Do you have any idea of why the SVM.EXE seems to be applying hi-color under DOS? Or is it just placebo, like it always 'seem' to set the resolution, even that it doesn't …

Yeah, it worked flawlessy. So yeah, you have to use 169-pin ODP Intel Overdrive, even that the motherboard has only one CPU socket. Kinda odd, but it works.
