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.

    LBA in mainboard BIOS, DDO

    My vintage 386 socket-PC is nearly complete and in a while I want to start writing posts here with it. Now, what I want:

    1) Is there a way to edit/modify/hack the mainboard BIOS so that I "add" the LBA support? I'm sure a super-duper hacker would be able to do that, but I looked for it, couldn't find anything for common mortals like myself. Opening the BIOS with a hex-editor, I couldn't understand anything other that the "BIOS text"
    2) If not, does anybody have a universal DDO software that will work with my SD-IDE "virtual HDD"? I tried the one from WD, it says it doesn't find a WD drive installed.

    Have you tried Anydrive?

      How big is the drive you're trying to install? I think ANYDRIVE will only allow up to a certain capacity of drives before it won't work. You could also give Ontrack Disk Manager a try if ANYDRIVE doesn't work.

        The "drive" is an SD card with an SD-IDE adapter. I use 8 GB cards as I had the LBA 8.4GB limitation in mind. Never heard of Anydrive or Ontrack Disk Manager. I'll give them a shot.

          AnyDrive has a 520mb limit, but Ontrack should do it, the WD tool you tried before was probably a version of Ontrack made to work on WD ROM'd drives, that was common back in the day, I know theres Seagate and Quantum versions just like that too. Ontrack DID make and sell a generic version that should work on ANY drive.

          Have you also looked into adding the XT-IDE BIOS to your PC? It can be burned to an EEPROM and installed in any bootable ROM socket, most common being "BOOT ROM" socket of NIC Cards.

            I was never a fan of OnTrack's DDO. For some reason Microhouse's "EZ-Drive" always seemed to work for me and it wasn't locked to a particular vendor's drives. Even then I used DDOs as a last resort as they make data transfer a pain (non-standard partition layout), I usually stick with LBA option ROMs.

                520Mb is supported in this mainboard already. I'll look into this "Ontrack".

                TBH I haven't looked into this before, as the "XT" name made me think it is for XTs. It sounds quite interesting the way I see it and I'll certainly have a look.

                If it is freeware, then I do want to try it, but isn't that for WD drives only?

                  Yeah, the point of ANYDRIVE, is for machines that ONLY have hard-coded BIOS drive entries for a FEW sizes, lets you overcome that UP TO the 520mb limit. Does not apply to your machine since its got manual entry or autodetect options, it was more for early 286 era prior to manual entry or some rare manufacturer-hobbled machines that tried to lock you into certain drive types.

                  It started out as an XT thing with the 8-bit XT-IDE card, however the BIOS has an AT mode that can be used with ANY IDE Controller, and its BIOS overcomes all the way up to 48bit LBA I believe (137gb).

                    I thought that too but it seems to support Seagate, Samsung, Conner, Fujitsu, JTS, Maxtor, Micropolis, Microscience, Toshiba, Rodime, HP and Quantum, as well.

                      FWIW, the latest version of EZ-Drive is 9.04. I believe the main difference is that it supports drives over 8.4GB.

                          If you watch ebay for an SIIG IDE ISA controller card, then you might be happy with the results. They look EXACTLY like this:

                          I have one, and it is probably the best IDE ISA controller cards you could wish for. It's about as fool-proof as you can imagine taking any hard drive up to the 8.4gb barrier. Its also VERY FAST! The last one I saw on ebay sold for $40, and I would agree its a bit steep, but if I lost the one I had, i'd replace it at that price.

                          found one on ebay:
                          http://www.ebay.com/itm/120989826683
                          It is a mistake to think you can solve any major problems just with potatoes.

                            I have this very card in my 486. Its a nice board and works fine with my Compact Flash cards. They also made a VLB version that pops up from time to time on ebay.

                              Well how fast can it be on the ISA BUS? This 386 board does have VLB slots and I have a few VLD IDE controllers with dual IDE and support at least up to PIO MODE 3. They do support LBA 8.4, but support is only enabled if the mainboard BIOS supports it as well.

                              Does this ISA controller "overcome" the mainboard limitation of not supporting LBA?
