After quick reboot my steps to repro the problem are as following: -> FreeDOS boots up, I enter NDN, browse to OpenWatcom 1.9 BINW folder and type 'wmake'
[Result] App shows all the info it should for no targets specified, I assume on exit it just crashes and hangs the whole system with a message: DOS/16M error: [26] 8042 timeout DOS/16M error: [26] 8042 timeout DOS/16M error: [26] 8042 timeout DOS/16M error: [26] 8042 timeout DOS/16M error: [26] 8042 timeout ... multiple lines with the same thing. Google search not helpful on the line that pops up. Now I wonder if this is part of - the OS - or the app (which is compiled against DOS4GW, 32bit protected mode extension, - or perhaps that refind and legacy bios or some hardware conflict is causing it or obviously combination of all.. but how to troubleshoot it more to identify the root cause? /h1 On Fri, Nov 13, 2020 at 10:53 PM Hollowone PL <hollowon...@gmail.com> wrote: > Thanks for your replies, to address your comments in one message: > > *[1] How did I install FreeDOS on iMac* > That was relatively easy once I installed this boot manager: > https://www.rodsbooks.com/refind/ > With it I can install Linux, Windows and FreeDOS from a bootable CD or USB > quite easily and aside of FreeDOS, no Bootcamp is required to start the > process. > Happy to provide more step by step instructions if they are really > required. > > *[2] 64bit stub. *Yes I'm aware of the software and the code.
