Forum 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.


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.


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.



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.


"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.

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.

    That would be very hard without source codes for the BIOS.
    You can find C&T chipset drivers here. Maybe one of them can be used to enable shadow RAM. That way you wouldn't need to use emm386.

        I have discovered that I can use a Sandisk CF/IDE converter with the Western Digital 9.06 overlay in place of less than 528MB hard drives.
        I am also going to try the IDE to SATA converter adapters and a Western Digital 500GB SATA hard drive with the WD overlay to see if that will work as well.
        Either of these will solve my problem w/o having to figure out why I have conflicts with the use of XTIDE and the machine's application software.

        Thanks for the help.

          I noticed my 486 DX2 66 box is taking longer to boot up, at first i thought it was my imagination but today i was actually sat staring at the screen when i switched it on, XTIDE Bios detects the drive fine but then takes about 20 seconds to get to "Booting C:", Likewise if i have the A: drive as the first boot drive it's the same. I rebuilt the bios using the "Boot_Menu" instead of the "HotKey Bar" and it takes about 20 seconds for the boot menu to pop up after drive detection, This is with r523 bios. I reverted back to r511 and boot up was much faster almost instant, Could this be due to the hotkey bar delay fix ?

            I would not be surprised if EZ-Drive doesn't go beyond 128GB (48bit LBA addressing limit). FWIW, new PATA drives in the 80-160GB range are still being made new, but sell for a high price compared to 500GB drives.

              Updated to r524 and my 486 box is happy again much better, I raised the "minimum time to display hotkeys" to 5 seconds as 2 seconds was too short and 5 seem's to be a happy medium on this box.

              Going back a bit to the "old" configurator there was an option to "Hide Rom Boot" are there any plans to bring this option back ? i thought it was a good option to have.

              Thanks

                This question is probably for aitotat and pearce_jj.

                I've been testing my version of XT-CF-Lite board. It does work with BIOS from James's site using two CF cards: a TOPRAM 4GB card and Kodak 32MB card. But I have several issues and questions:

                1. What is XTIDE Universal BIOS version the James's BIOS is based on? What are the modifications? Is there a patch (or a modified source code) available?
                2. James's BIOS doesn't work with Transcend 133x 4GB and 8GB CF cards. These cards don't get detected at all. BIOS prints "not found" very quickly. Cards model numbers are TS4GCF133 and TS8GCF133 respectively. The datasheet is available here.
                3. XTIDE Universal BIOS 2.0.0b3 doesn't detect any cards at all. I configured it as XT-CF / PIO mode. I also tried to configure 2.0.0b2 BIOS, but apparently it doesn't support XT-CF-Lite at all. With 2.0.0b3 it takes BIOS about 10 seconds to print "not found".
                4. At least the James's BIOS looks for secondary drive which is not available/not supported on XT-CF board. This is causes some delay during the boot. It not impossible that some later versions will support two cards, so it would be nice to make "look for the secondary drive" a configuration option.

                Thanks,
                Sergey

                  I've not looked at the BIOS (or the PCB) for a while - time has been a real problem. But the board is very simple; it just needs the BIOS configured as:
                  • Address lines CF A[0..2] mapped to ISA A[1..3] (this is the XT-CF mode of operation)
                  • IO Port base address per board, usually 300h


                  The date stamp on the BIOS is 2012-10-07 so probably it's quite old, I'll see if I still have the source. I did a lot of testing around R427-ish.

                  For the purposes of testing, work with 8-bit transfers (IN AL,DX), and move to 16-biit once proven. Some systems have issues with the BIU implementation that can result in reversed byte ordering when using that trick.

                  BTW I realised that the pull-down resistor on D7 might be inappropriate on the lite board, since there is no buffer. It's purpose is to aid detection of an absent device (i.e. slave) so should probably be removed and the BIOS updated accordingly to only look for master for these cards.

                  Will see if I can find any more info later. For the cards that don't work, see if you can manually pull the device ID data from the cards - I think Tomi has just such a utility available. Provided they support 8-bit transfers (which they must), they should work OK.

                    The BIOS on my site seems to be R476. Most likely I modified it to not check XT-CF status register (an XT-CFv2 feature that has been removed in the lite and the V3) and instead just use 8-bit port-mapped IO.

                      James, can you please send me a diff, or just all the source code with your modifications? Thanks...

                        Sorry, I can't find the source code. At some point I'll get on to revising a newer build to suit.

                          Quick question - are there any specific 16-bit ISA controllers out there that are known to work decently well in an 8-bit slot with this BIOS? (I'm led to believe that this would be a working setup to drive a CF card, feel free to correct me if I'm wrong)
                          Atari 800XL (fully working) - Ranasystems 1000 (status unknown - won't boot any of my current disks)
                          Commodore VIC-20 (mostly working)
                          Corona Data Systems PPC-400/luggable XT clone (hard drive dead, boots from floppy)
                          Packard Bell 486DX2-66 - SB16 clone, Intel Pro 8/16 NIC, 512MB CF "hard drive"

                            Correct. Check this thread for details: http://www.vintage-computer.com/vcfo...IDE-Controller

                              I've started work on r528 for XT-CFv3 and XT-CF-lite support. The existing official XTIDE Universal BIOS *will not work* under adapter type 'XT-CF' for these boards, since neither has a readable control register (an XT-CFv2 feature) which is used in initialisation, determining transfer type and auto-detection. I'll continue work this week and feed the revisions back to Tomi when I can.

                                I've just added support for the Silicon Valley Computer ADP50L controller. Anyone up for testing? See here for more info.

                                Thanks to Great Hierophant for providing the original BIOS!
