Re: [Freedos-user] Windows 3.11 issues about FreeDOS
Hi Liam, Windows 3.11 cannot be run in 386 enhanced mode on FreeDOS, as it shows ERROR: Unsupported MS-DOS version. Windows 3.11 can be run in standard mode on FreeDOS, but when I launch the MS-DOS Prompt, it shows Invalid Opcode. Is there anyone who can solve this problem? As far as I know, this is a known and documented issue. There are several factors. Windows for Workgroups 3.11 (unless in limited safe mode) and the 386enh mode of Windows 3.0 and 3.1 require DOS to be predictable and compatible enough to wrap themselves around DOS to be able to create several independent DOS tasks. The solution for THIS problem should be to use the kernel updates from Jeremy to implement some special API extensions for Windows. Unfortunately, they are not yet part of the distro, but I am sure somebody can mention a good download link here on the list? Another problem is that Windows cannot deal with large amounts of RAM, so you have to configure your EMM386 (yet another compatibility issue! It may be best to use the MS version??) and/or HIMEM (or maybe XMGR?) to only show an "understandable" amount and/or configure Windows to use a smaller swap factor. It cannot work with FAT32 or LBA as far as I know, so you have to tell it to use DOS and BIOS for disk access etc. So, no, for now it cannot be fixed. See above, there could be a chance :-) I hope this thread is seen by Jeremy and other experts :-) Maybe in some future version of DOS. Maybe sooner than we think. If you really need Windows 3.1x on a FAT32-capable DOS, then I would suggest DR-DOS from the DR-DOS Enhancement Project or possibly IBM PC-DOS 7.1. See above - Windows for Workgroups should have a more general problem with FAT32 and LBA, so first try to get it to work at all. Maybe a good (!) virtual PC configured to have "retro" hardware, little RAM, small FAT16 disk etc. is a start?

It is possible to run Windows 3.x in 386 Enhanced Mode on FreeDOS. https://virtuallyfun.com/wordpress/2021/07/27/freedos-running-windows-3-1 https://www.youtube.com/watch?v=35OQjLYdvJ0 W dniu 30.08.2022 o 04:53, Victor Yeh pisze: Hi, Windows 3.11 cannot be run in 386 enhanced mode on FreeDOS, as it shows |ERROR: Unsupported MS-DOS version.| |UnsupportedMSDOSversion.png | | | |Windows 3.11 can be run in standard mode on FreeDOS, but when I launch the |MS-DOS Prompt|, it shows |Invalid Opcode|. | |InvalidOpcode.png | | | |Is there anyone who can solve this problem?| | | | | |Regards,| |Victor| ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

I have download links for both on my blog, but I've been accused of spamming in the past so I won't give the links. I think they should be easily Googled and I've shared them on both Reddit and Facebook in the DOS groups. -- Liam Proven ~ Profile: https://about.me/liamproven Email: lpro...@cix.co.uk ~ gMail/gTalk/FB: lpro...@gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven UK: (+44) 7939-087884 ~ Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053 ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
