MS-DOS 6.22 from usb to HDD

July 15, 2013 at 07:58:15
Specs: windows XP

Trying to install MS-DOS 6.22 on a flash drive, then from this flash drive use it to install MS-DOS 6.22 on to HDD connected through USB ports.

My Bios does have legacy support

You've got the right forum.

Dos doesn't recognize USB ports and therefore won't see anything connected to them without the addition of special drivers. There's some info here:

Does the computer you're doing the install on have a floppy drive? I assume you have the 6.22 floppy installation disks? How big is the external drive? 6.22 only works on fat16 partitions which can be no larger than 2 gig. Most external drives are going to be much larger so you end up with many logical drives or wasted space.

If your eventual goal is to get 6.22 installed on a hard drive, the easiest way is to connect the drive internally and do a regular install with floppy disks. Can you temporarily remove the external drive from its enclosure and connect it internally? Is it an IDE/ATA drive and not SATA?

You can experiment with the suggestions and maybe find something that works for you but the easiest way would be to use the traditional installation method.

Yes, Does not support USB, so I've tried using DUSE.sys and USBASPI.sys and putting them in command line in config.sys.

I have a 2 Gb transcend external SATA SSD drive. And I am okay with wasted space.

My set-up is ancient technology that has to have 6.22 DOS. And the IDE flash drives are getting hard to come by, so I was moving to an IDE to SATA adapter seen here:

I used this bc it said no driver required. Then next step would be plugging sata in via USB to sata adapter to reformat it to dos 6.22. Then plug into machine.

I'm using a laptop, that I currently can not open up to get to the insides.

Ultimately, I want to know can this work with all of the stuff out there for DOS? Or am I wasting my time.

These are the things I have attempted to do:

Through a bootable floppy disk (connected through USB) I have tried using DUSE.sys, USBASPI.sys, But this is my first time dealing with DOS. Therefore, I don't really understand everything that needs to be in Autoexec.bat and in Config.sys to make these files do what they claim to do. Also, I was able to get them to start "initializing drives" but then they would fail. That to me seems the easiest solution but i also want to get away from using floppies because they are becoming obsolete.

Now about getting DOS 6.22 onto a usb drive, every program out there installs something higher than that, including the following:

I'm sure others too.

So then I tried to figure out what made a drive bootable or not. I found out that there is something called a boot sector that has to be present. Therefore, my next plan was to try to make a bootable sector on a usb drive and then copy 6.22 files over from a bootable floppy to the usb. I using MKBT20 and the steps in the text file:

To install bootsector from file "bootsect.bin" onto drive A:
-> mkbt c:\os\dos622\bootsect.bin a:

To install bootsector from file "bootsect.bin" onto floppy image "288.img"
-> mkbt c:\os\dos622\bootsect.bin c:\tmp\288.img

To copy bootsector from a bootable floppy in drive A: to a file called
-> mkbt -c a: c:\os\dos622\bootsect.bin

However, I was unsuccessful and received some error when doing this.

Lastly, in my most recent findings, there the IO.sys and MSDOS.sys have to be the first two files on the drive that needs 6.22.

All of these ways I have been unsuccessful in doing, however, this could be due to my inexperience with these programs and DOS. For all I know I did it wrong and all of these ways are possible options when done correctly.

I've never tried anything like what you're attempting so I hesitate to suggest things that likely won't help.

I don't see how installing 6.22 on a flash drive will help to then install it on an external hard drive. It seems to me that since they're both USB devices then if you can install dos on a flash drive you can use the same method to install it on the external hard drive. Google shows a lot of interest in installing dos on flash drives. Here's one:

But I suppose your previous searches have found a lot of that. If you can make it bootable then I suppose you can manually copy the rest of the dos files to it.

However, my suggestion would be to get a desktop computer, attach a regular IDE drive to it and install 6.22 on it and then clone that drive to the external. Or since I don't know what your specific needs are, if you have an application that requires 6.22 maybe you can set up a separate dos-only computer.

First of all, I really appreciate the replies. I agree with what you have said it seemed to me that if i found a program to install it in a usb why not just use it to do a Hard Drive? Well, that is just the problem, surprisingly all of the programs that let you make a flash drive bootable will not let you select a hard drive.

The only other problem with the flash drive programs are that none of them use the DOS 6.22 they are all at least 7.1+ at least from the one's i've found.

However, your suggestion seems genius. This process of cloning does it essentially make the exact same drive as the one that was cloned. Including the bootsector etc, so that it will be bootable? With that being said, can I clone the drive in xp (through usb interface ex drive f:\) and then copy that clone to drive g:\?

Basically, I'm just trying to use newer technology to make ancient technology. In other words, use XP to make bootable DOS SSDs.

Ah yes and this is also because I only have laptops and can't easily get to the HDD inside of it. Anyways, just let me know what you think, looking to hear more advice from you.

Oh just a small edit:
Is it possible to use a newer version of msdos (anything, ME, PE) and install an earlier version aka the version I want... dos 6.22?

Newer dos version should be just as easy (hard?) to install as 6.22. 7.1--which I think is win98 dos--and freedos should be fat32 capable so you wouldn't be limited to 2 gig drive sizes. I wouldn't put on an older dos version

Under normal circumstances a cloned drive will work exactly the same as the original--it will boot and run the software the same. I have some concerns about dos on a USB SATA SSD drive but I would think if you can get it on there it will work OK.

To clone a drive to the external you need to make sure whatever software you use will work with the external. (I think you can assume any cloning software will work with an old IDE drive.) The support site for the external drive will likely have cloning software that will work with it. Most use a version of Acronis that is branded for their own models. I'm not sure if you can boot from one drive and then copy a second drive to a third drive. I've never tried it that way. You'll just have to try and see if it allows that.

It's going to be harder to do it with laptops. You can probably find an old P-4 desktop at a garage sale or thrift shop. It's going to be hard to do the original dos install on anything but an internal IDE connection. Other options would be to get a new laptop drive and swap it in to do the dos install and then maybe put it in an external enclosure. Then you can put the original XP drive back in. Then both the dos drive and the drive you want to clone it to would be connected externalliy to USB ports.

Also if you did find a desktop to install dos on you could remove its drive after the install and put it in an external case and set it up as above.

Well, just some thoughts. What you end up doing depends on what hardware you can find and the capabilities of the cloning software.

Hey guys, if you have since figured a way to install dos 6.22 from floppies in a usb 3.5 floppy to an external IDE HDD connected via an adapter (both connected to a laptop) I sure would appreciate it. I got a medical device that uses IDE HDD's loaded with proprietary software on dos 6.22 and want to have backups available.

Thanks in advance!

I'm not sure how you intend to use it but dos installations aren't picky about being moved from computer to computer as are windows versions. So if it was me I'd install dos on an IDE drive in an old desktop and then attach it externally to the other computer.

Note that dos 6.22 only installs on FAT16 partitions which have a maximum size of 2 gig. And I'm not sure about disk access. It should boot OK but I'm not sure about reading and writing to the drive after that. You may have to do some experimenting.
