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.

        Yes of course. Point your subversion client to http://www.xtideuniversalbios.org/sv...rsalbios/trunk and then do a checkout. If you don't have a client then I'd recommend using TortoiseSVN (assuming you're using Windows). The instructions at https://code.google.com/archive/p/xt...tructions.wiki might also be useful even though that page is a bit outdated.

            Any plans for adding ATAPI (CD-ROM) support?

            Comment


              I would like to add detection of ATAPI devices at some point just to show that the device is detected at boot. Anything more than that is going to take serious effort because it would require El Torito and/or ARMD support.

                XUB r606 is out!

                Thank you Montecarlo4tony for reporting the problems with 32-bit disk access drivers under Windows 3.x! RESERVE_DIAGNOSTIC_CYLINDER is now completely removed so your patch should not be needed anymore. Thank you Pickle for providing the BIOSDRVS output that lead to the discovery of the CHS translation bug!

                Please note that this revision involves changing the CHS translation for some drives - affected drives must be repartitioned and reformatted after upgrading to this revision of XUB! See the link for more info!

                  Native support for QDI Vision QD6500 and QD6580 VLB IDE controllers
                  1) Does it mean that is not necessary to change 32bit device type (as default is 16b) ?
                  2) I tested it with other VLB cards (not QD, not promise) and works. Does it mean that the best performance is with QD6580 card?

                    Upgraded my V20 XT clone, V30/8086 IBM and 286 IBM, no issues except for forgetting that I run the XTP image on the 286 instead of the AT image because I have an xt-lite card in there. Not ideal for speed I know.

                      1. Yes.
                      2. Other VLB cards will still work as regular ISA 16-bit IDE controllers with no performance improvement. So yes, you will get the best performance with a QD6580 card.

                      XTP vs AT images shouldn't matter regarding performance. Or were you referring to running an 8-bit controller in a machine with 16-bit bus?

                          A CHS Translation *Bug* ??
                          Now i gotta remember to manually set the " CHS Translation Mode " to LBA, Otherwise i get the "Missing operating system" error.
                          No big deal, The CF cards i use in my XT's support LBA, I use a much newer / faster system to set my CF cards up.

                            Could this 'bug' be responsible for disk content over >8GB being inaccessible? This is using a r605 ide_386l image on a 3c509b.

                            I've got some CF cards and modern hard drives all over 8gb that I am trying to partition and format with Win98se or PC-dos 7.1 fat32 (and they do so just fine) but fail at accessing any content I drop on to them over ~8gb...

                            But connect them back up to a modern pc and all the content and files are there.

                              Yeah, forcing the translation mode to use LBA can be used if you want to avoid repartitioning and reformatting the drives. The downside of using LBA is that you might lose a bit of disk space due to rounding because of the translation. The translation also makes disk accesses a bit slower (not sure how much slower, though).

                              No, this bug affects only small drives with 1024 cylinders or less. So basically drives with sizes up to 504 MiB or 528 MB. MS-DOS 6.22 and older versions has a drive size limit at about 8 GB. So which version of DOS are you using?

                                So far I've tried the Dos 7.1 as included on a Win98SE boot floppy, as well as IBM PC-DOS 7.1. Both are fully FAT32 aware, as far as I know.

                                Both will partition the drive(s) and format them as normal (a small C:, another ~7GB for D:, and the remainder for E: - so E: stretches from just below 8GB to the remainder of the drive). I've even tried a big 64GB CF card and a couple of 2.5" IDE laptop drives and both Win98SE and PC-DOS 7.1 are happy partitioning and even formatting partitions up to the maximum size of the drive. All devices I've tried experience the same behaviour I describe below.

                                However, if I go back to my 16GB card that I'm using - I put a basic bootable system on C:, check it can boot and then remove the drive to copy content on to it from my Linux workstation.

                                On accessing the drive back in the XTIDE system again, all content copied to C: and D: is present and correct - absolutely zero problems. If I left things there, the system is absolutely fine, everything works. But, if I copy enough content on to E: so that directory entries and file content is beyond 8GB (say 2GB of data), I see empty directories, corrupt filenames or dir will simply lock the computer up.

                                Remove the card and put it back in to a modern PC and all the content is still there, absolutely fine.

                                Output from biosdrvs.com:

                                xtide_biosdrvs.png

                                Win98SE fdisk output, one primary and one extended partition:

                                xtide_fdisk1.png

                                Two logical drives, with E: extending from under 8GB to the end of the (16GB) drive.

                                xtide_fdisk2.png

                                Drive C: is fine, so is D:, and here I've got several GB of content copied to E:, root directory entry looks okay:

                                xtide_dir_sizes.png

                                ... but trying to access virtually anything from that third partition which is beyond 8GB generates rubbish:
