Hello all,

I have some problem with this floppy card:

http://www.vintage-computer.com/vcforum/showthread.php?16908-What-kind-of-Floppy-controller-is-this

I have the same card as mentioned in the thread link above.. But i dont have the actually bios rom for it.. So i cant use the HD floppy options..
I had contacted the new owner of this card, but he dont know how to dump the bios rom to file..

Myself using a eprom reader / writer the dump those images.. But i can guess that the owner with the bios card doesnt have one..

I red a the past that i also could do it with the program called `debug` ... I guess this is just a ms-dos program?

But i want to know how need it be used to dumping the bios rom to file.. Because i needed this rom very much, because the actually owner of the rom could be the only one on the world with this working rom..
And iam not that greedy to, because i will make it shareble..

Could anyone explain me how to use the debug option (if it could work) to dump the rom to file?
 
I know I've got some software tucked away that reads and saves the ROMs to a file. That's a lot simpler than using DEBUG! :)

Where can i find that software? I only want to save that floppy controllers bios, but not from the motherboard he have.

So this is de file iam need to look for?

To use DEBUG, you need to know two things:
1. Address of ROM; and
2. Size of ROM.

The photos in the thread that you pointed to indicate a 27C64 type ROM, i.e. 8 KB sized.
But you do not know the ROM address.

That program copies all of the memory from C0000 to FFFFF into a file named DUMP.BIN
DUMP.BIN will be 256 KB sized.
The 8 KB ROM from the floppy controller will be somewhere in DUMP.BIN

If you cannot find the ROM content in DUMP.BIN, then email me DUMP.BIN and I will find it, placing it at http://www.minuszerodegrees.net/rom/rom.htm
 
ree has worked well for me, the BIOS has to be 64k or less. It's runs under either DOS or Windows. All you do is run the program, it steps through all BIOSes found and you either tell it y or n if you want it to copy to disk.

The website is at http://gnu.ethz.ch/linuks.mine.nu/ree/

The download you want for DOS or Windows is http://gnu.ethz.ch/linuks.mine.nu/ree/ree-1.3.tar.bz2
The archive with the DOS/Win version is nested 3 layers deep in the archive, it's named ree_dos_win9x.zip
The archive is attached to this post for ease of acquisition, more info at https://launchpad.net/ubuntu/+source/ree/1.3-2.1

here is info from the readme
"will scan your system memory, address c0000 - f0000 in 512 steps for
identification of rom extensions (55,aa), if found it will calculate
its size (byte after id, multiplied by 512) and save that to a .rom file.

note
as most system bios are bigger than 64k nowadays (128k or 256k) and them
are only 64k memory window reserved, they are not dumped completely, if
anyone knows how to dump the completely, please contact me"

I dont think debug will do.. For a beginner its just to hard to understand i guess..

But i can try ree instead.. Thanks. i will try.
