Forum Rules and Etiquette

Our mission ...

This forum is part of our mission to promote the preservation of vintage computers through education and outreach. (In real life we also run events and have a museum.) We encourage you to join us, participate, share your knowledge, and enjoy.

This forum has been around in this format for over 15 years. These rules and guidelines help us maintain a healthy and active community, and we moderate the forum to keep things on track. Please familiarize yourself with these rules and guidelines.

Rule 1: Remain civil and respectful

There are several hundred people who actively participate here. People come from all different backgrounds and will have different ways of seeing things. You will not agree with everything you read here. Back-and-forth discussions are fine but do not cross the line into rude or disrespectful behavior.

Conduct yourself as you would at any other place where people come together in person to discuss their hobby. If you wouldn't say something to somebody in person, then you probably should not be writing it here.

This should be obvious but, just in case: profanity, threats, slurs against any group (sexual, racial, gender, etc.) will not be tolerated.

Rule 2: Stay close to the original topic being discussed
  • If you are starting a new thread choose a reasonable sub-forum to start your thread. (If you choose incorrectly don't worry, we can fix that.)
  • If you are responding to a thread, stay on topic - the original poster was trying to achieve something. You can always start a new thread instead of potentially "hijacking" an existing thread.

Rule 3: Contribute something meaningful

To put things in engineering terms, we value a high signal to noise ratio. Coming here should not be a waste of time.
  • This is not a chat room. If you are taking less than 30 seconds to make a post then you are probably doing something wrong. A post should be on topic, clear, and contribute something meaningful to the discussion. If people read your posts and feel that their time as been wasted, they will stop reading your posts. Worse yet, they will stop visiting and we'll lose their experience and contributions.
  • Do not bump threads.
  • Do not "necro-post" unless you are following up to a specific person on a specific thread. And even then, that person may have moved on. Just start a new thread for your related topic.
  • Use the Private Message system for posts that are targeted at a specific person.

Rule 4: "PM Sent!" messages (or, how to use the Private Message system)

This forum has a private message feature that we want people to use for messages that are not of general interest to other members.

In short, if you are going to reply to a thread and that reply is targeted to a specific individual and not of interest to anybody else (either now or in the future) then send a private message instead.

Here are some obvious examples of when you should not reply to a thread and use the PM system instead:
  • "PM Sent!": Do not tell the rest of us that you sent a PM ... the forum software will tell the other person that they have a PM waiting.
  • "How much is shipping to ....": This is a very specific and directed question that is not of interest to anybody else.

Why do we have this policy? Sending a "PM Sent!" type message basically wastes everybody else's time by making them having to scroll past a post in a thread that looks to be updated, when the update is not meaningful. And the person you are sending the PM to will be notified by the forum software that they have a message waiting for them. Look up at the top near the right edge where it says 'Notifications' ... if you have a PM waiting, it will tell you there.

Rule 5: Copyright and other legal issues

We are here to discuss vintage computing, so discussing software, books, and other intellectual property that is on-topic is fine. We don't want people using these forums to discuss or enable copyright violations or other things that are against the law; whether you agree with the law or not is irrelevant. Do not use our resources for something that is legally or morally questionable.

Our discussions here generally fall under "fair use." Telling people how to pirate a software title is an example of something that is not allowable here.

Reporting problematic posts

If you see spam, a wildly off-topic post, or something abusive or illegal please report the thread by clicking on the "Report Post" icon. (It looks like an exclamation point in a triangle and it is available under every post.) This send a notification to all of the moderators, so somebody will see it and deal with it.

If you are unsure you may consider sending a private message to a moderator instead.

New user moderation

New users are directly moderated so that we can weed spammers out early. This means that for your first 10 posts you will have some delay before they are seen. We understand this can be disruptive to the flow of conversation and we try to keep up with our new user moderation duties to avoid undue inconvenience. Please do not make duplicate posts, extra posts to bump your post count, or ask the moderators to expedite this process; 10 moderated posts will go by quickly.

New users also have a smaller personal message inbox limit and are rate limited when sending PMs to other users.

Other suggestions
  • Use Google, books, or other definitive sources. There is a lot of information out there.
  • Don't make people guess at what you are trying to say; we are not mind readers. Be clear and concise.
  • Spelling and grammar are not rated, but they do make a post easier to read.

Windows 10-compatible motherboard with dual floppy drives?

    Windows 10-compatible motherboard with dual floppy drives?

    I'm looking to run 3.5" and 5.25" floppy disks in a machine that will run Windows 10.

    I've found some socket 478 and 775 boards that recognize dual floppies, but the hurdle for running Windows 10 on them is that they lack the Execute Disable Bit in their BIOS.

    I'd prefer not to use a USB solution because I want to use my existing dual floppy drive and write to the disks: A feature that the 5.25" USB controllers I've found lack.

    One further requirement is that I need an ITX or otherwise small motherboard because I'm stealthing the build inside an IBM 5150 chassis.

    There are Core 2 Duo/Quad motherboards that have floppy controllers, but I'm not sure if the BIOS will support the 5.25 and 3.5 drives.

    You might have better luck with an AMD solution, some of the AM2 and AM3 boards ( like the ASUS M4N78 ) have floppy ports.


      I think it's gonna be a tough challenge to get all the necessary and still compatible ingredients together to meet this project's demands.

      10 does not play nice with BIOS.

      5" drives won't run with that hardware and don't really come in the USB flavor, anyway.

      All in all it'll be quite a feat to put this together within reason so be sure to keep us informed as to how you finally end up doing it.

        Be polite and I may let you live.

            My Nforce4U chipset Athlon x2 3800+ system does support 5.25 floppies, but not windows 10 as it doesn't have the CMPXCHG16b instruction.

            My socket AM3 board, M4A79XTD EVO, supports windows 10, but has no floppy controller.

            The Core 2 Duo boards might be the best bet, or a socket AM2 board, like this board: ASUS M3A78-EM


              The ASRock 980DE3 is inexpensive and still current. Has both IDE and FDC (1 drive only) as well as SATA.

              I'm sitting in front of one right now.

                Before you start pulling those old motherboards out of mothballs, you are going to need to address the question of driver availability.

                Latest OS:
                Make sure you are running the latest version of either Windows 7 SP1 or Windows 8.1 Update.
                Don’t know which version you are running? Check here to find out. Need to download the latest version? Click here for Windows 7 SP1 or Windows 8.1 Update.

                1 gigahertz (GHz) or faster processor or SoC

                1 gigabyte (GB) for 32-bit or 2 GB for 64-bit

                Hard disk space:
                16 GB for 32-bit OS 20 GB for 64-bit OS

                Graphics card:
                DirectX 9 or later with WDDM 1.0 driver

                Surely not everyone was Kung-Fu fighting

                  The M3A78 mentioned above has driver support in Windows 8.1 64 bit, so it will likely work with Windows 10 out of the box. Socket AM2 processors have the necessary instructions and speed to support Windows 10, it just won't be as fast as current hardware. Unfortunately, the BIOS only supports a single floppy drive (this may be a limitation of the AMD SB700 chipset).

                  However, nVidia made a number of AM2/2+ chipsets that do support two floppy drives. Finding one in the smaller form factor with the floppy connector supporting two drives might be the fun part....


                    Hmm... the modern motherboards with floppy controllers only support a single drive, but many do support 1.2mb 5.25/360k 5.25 still.

                    How about a 5.25 drive on the internal controller, and a USB connected 3.5 drive?


                      Please note that for some AMD chipsets, it is necessary to turn off the High Precision Event Timer in order to use the motherboard floppy controller.


                        I've seen this come up before and I think I have the best solution. This is the board I personally use in my garage. It is small, POWERFUL and has an extra cool factor of having 2 sockets.


                        That said, the bios only supports one floppy drive. I worked around this by placing my 5.25 drive on the mobo and using an LS-120 drive as my 3.5 drive.
                        It is a mistake to think you can solve any major problems just with potatoes.


                          My msi x58m board supports only 1 floppy drive, but it supports 360kand 1.2m 5.25s and 720k and 1.44m 3.5s. there may also be a way to enable 2 drives. bit if youre going for the authentic 5150 look just use an original 5150 drive and have an external 3.5. That is the only newish board I know of to support it, and its micro atx, which would work perfectly with the 5 slots on the 5150.


                            No motherboards fit the 5150 case except 5150 boards, unless you cut up the back of the case. The slots are too far apart. IBM moved them closer together on the XT and that has been the standard ever since. You may have to cut the drive bays for clearance, as well.


                              And many did, unfortunately.
                              Be polite and I may let you live.
