Yep, that is correct. Due to it, I had to recompile my own OpenWatcom build using a different extender for runtime to continue using it (which is fine). I also continue investigating the root cause of that limitation. Just spoke to rEFInd developer to assess his opinion. Seems that he shares one

Hello Ralf Quint, I am not sure if you guys all missed a previous post where I said I found a reference that there are issues with some SMM BIOS implementations, providing legacy USB support (for keyboard and mice) and software that is trying to switch in "long mode" (which also might be used

Hi! I like TK Chia's idea that DOS/16M tried to access the keyboard controller to change A20: It would probably stop doing that when HIMEM and/or EMM386 are loaded, but having a DPMI loaded can be even more convincing. Same for DOS4GW: If A20 control is already provided by something else, or

This is a very interesting point regarding the keyboard. I have a standard USB keyboard (actually from Microsoft) that is connected to this iMac and standard HIC USB mouse that works with I think everything (including a few FPGA computers I run retro stuff on. With such a setup, the keyboard

Hello Hollowone PL, hello Eric Auer, DOS/16M error: [26] 8042 timeout DOS/16M error: [26] 8042 timeout ... The 8042 is the keyboard controller. You are using the rEFInd boot manager on iMac, without Bootcamp. I assume that means you had to load some CSM, either provided by Apple or by rEFInd,
