[Server] Boot from floppy without floppy connector

Posted 18 February 2012 - 05:23 AM

Hello everyone,

I'm busy with building my own OS for a while.
Now I should like to test this on my server machine, with a floppy as boot-medium.

The problem is just, the server machine doesn't have a floppy drive connector.
It only has:
- 2 IDE 40-pins
- 1 PCI
- 4 USB ports

I've read something about LS-120 drives, which could connect to IDE connectors.
But these things are quite expensive for my little project, so I would first consider other options.

There is an boot option on the BIOS of the machine which is called "USB-FDD", I don't know what kind of thing this is.
I mean, I don't think this is a USB Floppy drive, because those drives needs drivers installed on the OS, before connecting and there isn't a OS running before it has been booted.

So I have been looking and I found: http://www.geekalert...usb-floppy2.jpg
Is this the thing I need? Isn't this just handled as a USB-stick. (It doesn't fit in a floppy drive, so it isn't a floppy anymore, right?)

To come to the point:
Could someone give me advise how to boot my server, which has no floppy-drive connector, from an floppy?

Thanks,

Sinned

Can the machine boot from a USB thumb drive? You know newer-ish machines can do that... also why not just burn it to a cd and boot from that?

Plus that photo is just a usb thumb drive shoved into a floppy disk as a promotional item.. it is *not* a magical floppy disk to usb.

No, it's an old machine.

This could be possible if I only should do it once.
But what I have to do is: test, edit, test, edit, test, edit, test, edit, etc...
So this isn't possible.

I was already supposing something like that, but it looked like an USB-FDD, so I thought maybe it could be it. :P

If it's that old then it should have a FDD connector for a floppy drive and then you just buy one off ebay.

If it comes to the worst then twenty five bones gets you a spindle of a hundred CDRs... use the re-write option on a cdr to get a few uses out of it and stretch those hundred...

Also don't forget about CD-RW disks are available.

To come back to this old topic of mine. (It's still top list, and this problem goes on with it)

I've been trying many things to boot it.
Now I think: maybe I can boot it from CD. :P
But I don't know how to write sectors right to the CD.
With floppies I could just do:
dd if=boot.bin of=/dev/fd0 bs=512 count=1
I can't do that with a CD, CD's need an ISO format or something ??

I don't know how to write my boot sector (512 bytes) direct to the CD.
I was hoping someone could tell me how to do this. :)

Thanks,
Sinned

But... I read already something like that.
I thought this isn't where I was looking for...

This creates some sort of file system on the CD with some start-up .bat files ???
I just want to burn 1 sector of 512 bytes to the first sector of the CD. (The same as just burn 1 sector to a floppy)

At least I thought so.

It also returns an error:
Size of boot image is 4 sectors -> bin/mkisofs: Error - boot image 'cds\cdromsi\
files/cdrom.img' is not the an allowable size.
BCD: mkisofs.exe returned an error...
BCD: Aborting, removing ISO file "C:\Users\Dennis\AppData\Local\Temp\bcd.iso"
BCD: Aborted...

(C:\Users\Dennis\ is my home directory, I'm Dennis)

Yeah - well you really don't write a cd like you would a floppy disk.

I made a boot CD working with Nero ROM 11.
I can just insert the (assembled) .bin file. (bootloader)
And it burns it directly to disk.

I know it's not the best method, because I simulates an 1.44 MB Diskette. (So the maximum capacity is 1.44 MB)
But it works for now.
