Title: Dealing with .img floppy images on a slab
Post by: blakespot on July 06, 2014, 04:34:20 PM
I have a few ~1.5MB .img floppy images that I want to use to install an app on my slab. Is there a way to deal with them in image format, or must I write them out to 1.44's? If so, how?

I don't have a PC or a Mac with a 3.5" floppy drive (other than my Mac Plus w/ 800KB drive).

Thanks...

I don't know a loopback driver for the NeXT, so the only way is to write back to a disk. you can do that with rawrite http://www.chrysocome.net/rawwrite on windows. Maybe it works with a cheap USB-drive

At this point in time, it may be easiest if you install NeXTStep or OpenStep for Intel on a PC emulator (perhaps VirtualBox or qemu, both of which are gratis), attach the floppy images there and read them, and use a network connection from the virtual machine to a real one to transfer the files from the floppies to your slab?

You can write the .img files back from your slab to floppy disks like this:

dd if=name.img of=/dev/fd0a

Without bs parameter this will take a while, but in the end it should succeed.

I have a miracle soft on my slab wich can handle disk image directly from the nslab (not to the point to "mount" virtual disk, but you can read and write real disk, even 2.88 one). Need to find it before my SLAB goes to a loooong sleelp away from me.
