to create DOS bootable system disk under Linux

[openmind]

Hi

How can I create DOS bootable system disk under Linux. I am trying to fix crashed BIOS from 1998. I already found firmware and I need a floppy on which I can write it. By the way, is it right to use FAT16 FS for 1.44 MB floppy? I am not very familiar with dividing disks, so need a little help 🙂

AFAIK you'll need to download a DOS image to put on the floppy.

Is it an image? (ie. needs rawrite.exe or whatever?)
dd will work if that's the case.

thanks guys 🙂, but...

I already have BIOS files xxxx.ROM and xxxx.BIN. The question is - which FS(on floppy disk) should I use to be able to place this files on floppy disk. And which command?
I tried cfdisk but it can not read partitions table on floppy at all, then I tried

fdisk /dev/fd0
Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 
Value out of range.
Partition number (1-4): 1
First cylinder (1-80, default 1): 
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-80, default 80): 
Using default value 80

and than created one partition (FAT16) on free space with help of cfdisk
but now I can't mount floppy disk to place BIOS files on it

mount -t vfat /dev/fd0 /mnt/floppy/
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
dmesg | tail
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev fd0.

can't get what he is trying say to me, don't know what to do :hmm:
Colt45, no, the files are not image, unfortunately the image is not available
