Can an Amiga write MS-DOS disks from an image?
« on: November 04, 2007, 01:41:27 PM »
I'm thinking of trying to get PC-Task up and running, simply because I have never tried it on anything faster than an 040. I don't have a PC I can use to create a DOS boot disk. Is there any way I can download a boot disk, e.g. from bootdisk.com, and use my Amiga to transfer the image on to a real floppy for use in PC Task? I am of course aware of tools which write disk images to floppy on the Amiga, just not sure if they can be used in this way with an MS-DOS image.

I don't think mounting the image is the answer. After all you don't mount an ADF before writing it to a disk. I just want to dump the raw contents of the file on to the disk, regardless of filesystem. I would imagine this is possible, since the Amiga doesn't have to understand what's in the image in order to write the tracks to floppy (I assume). Also, it's a 1.44MB image. I think the floppy drive in my A4000 is HD, so it should be ok - as long as the software doesn't stop after 720/880k.

I'll just try it and report back :-)

Just tried ADFBlitzer and I don't think it wrote the whole disk - I counted only 40 clicks from the drive and then it stopped. I then tried the Amiga port of dd to pipe the raw file directly on to the disk, but this failed with an "unspecified error" after about 500 bytes :-?

[EDIT]
Anybody know if it is enough to format PC0, then put command.com etc on to it, from the Amiga side? Will that boot under PC Task?

@Andy
Yes, it's /s. But doesn't that just copy command.com et al so the disk will boot? Not sure whether it does anything to the bootblock of the disk itself to make it bootable (i.e. with AmigaDOS "install" command).


@MarcFrick
Just had a look on Aminet for that version and can't find it. Could you let me know where you got it?


This may all be academic now since I don't seem to have PC Task on my Amiga any more, and I think my CUCD with PC Task on it is long gone :-(

Just a quick observation: Everyone screams murder at the first sign of Amiga piracy, but an open discussion of pirating MS-DOS goes unchecked. Silliness.

Where did that happen? Who mentioned pirating MS-DOS?

Anyhow, MS-DOS bootable disks consist of the following:

The problem is I have no way of creating the disk from within a DOS environment since I don't have a PC with a floppy drive. That's why I was trying to write the disk image from bootdisk.com directly to a floppy with my Amiga.

None of the images on bootdisk.com are legal. ;-) FreeDOS is an excellent substitute, but it's not truly 100% MS-DOS/PC-DOS compatible.

Really? I didn't realise that. Although didn't MS give DOS away at one point anyway?

In the same way that most Amiga software is perceived as free or abandoned?

No, I thought MS actually allowed people to download it. Maybe I'm thinking of Apple with System 7.

Thanks Thomas. I will try your suggestions once I have located my copy of PC-Task.
