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.

    Yes, always use the latest version. I will post in the v2 beta testing thread if/when I or someone else commits code unsuitable for use. Don't worry about the v2.x versions being 'beta' just because they explicitly say that in the version string. As I see it, they are all beta versions, more or less.

    Keep in mind, if everyone only uses old versions then development will stop due to lack of testing and feedback. Yes, it sucks to be a guinea pig but if I were to do all the testing myself, then it would be extremely time consuming, and expensive (to acquire all the hardware). Yes, I'm a cheap bastard.

    What are the pro's and cons of the different versions?
    The only 'pro' I can think of with regard to v1.1.5 (and earlier, I suppose) is that the harddisk benchmark in Norton Utilities SI.EXE works. With some builds of v2.x it will (appear to) hang the machine.

    Pros for v2.x;
    * Support for more hardware (different types of harddrive controllers and of course the virtual serial drive feature).
    * It's _required_ for the XT-IDE v2 and v3 "High speed mode".
    * More features in general (power saving for example).
    * It's compatible with (can run from the ROM socket on) 3Com 3C503 cards unlike older versions.
    * Higher performance.
    * It's modular which is great if you want to make your own custom builds from source using only the features you want.

    Note that I'm talking about the latest versions here, not the official releases available from Google Code.

    I'm sure other people can add more pro's and cons to the list (for old and new versions). I would be interested to hear if anyone is using an older version (v1.x) for some specific reason.

      Chuck's modified version of Hargle's BIOS also works with the high speed mode/Chuck Mod. That's what's running on my Chuck Modded rev 1 card.

        I have no idea any longer. When I came home today and tried the flashing utility it suddenly said "Found 1 controller" on the auto-configure option. It wasn't kidding either, Master at 80h: WD something...
        The problem now is that I have no idea how I can make this bootable now. The partitioning I tried on another pc didn't work. I tried using windows formatting to clear the drive (unformatted) and used fdisk from PC-Dos 3.3 to create a primary C Partition. So far so good, then comes the next big issue. I type in "C:" it changes fine. I try "mkdir DOS", then "Error reading drive C: " Is there some special formatting I have to do in order to use it?

          Ah yes, that's true. I had forgotten about that. Are you using that version for a specific reason?

            It would help to know what drive you are using.

                Not really, I burned it into an EPROM back when Chuck published his modification. It works fine, so I haven't seen a need to replace it.

                  You don't really expect to be able to use a 250GB drive with DOS 3.3 do you?

                    I thought any size was fine, but dos would only see some of it.

                      That ~may~ be correct but DOS 3.3 can *only* see 32MB partitions.

                        How can I make a 32MB partition? If I try fdisk it doesn't work. fdisk option 4 reports the created partition as: "Start: 0, End: 3, Syl: 4. Total sylinders: 1024"

                          Does FDISK give you the option to... Delete non-DOS Partition ... in its menu?

                          Aside from that a much better alternative would be to use DOS 6.xx or 7.x.

                            Re BIOS version, the main reason to use v2 is that Tomi, Krille and Gregg have poured hundreds of hours into this code to make it as fast and as compatible as it can be.. It works, it works well, and none of these projects would be possible without their efforts.

                              Incidentally FAT12 can put-perform FAT16 for random IO because the resultant FAT fits in the DOS buffers; digging out some DOS2 disks can be worthwhile.

                                You'll probably need to use DOS 5 or 6.22 to delete the partition. Start with no partitions at all on the drive, and do all partitioning/formatting with DOS 3.3, if that's what you're going to use.

                                And yes, you can use a 250 GB drive, you'll just waste almost all of it. Part of the reason I recommend people use smaller industrial Flash modules, or CompactFlash Cards.
