Hi All,
i am having a problem up[censored] IBM ServerRAID cards. i have the SUSE.img that i downloaded from ibm.com.
the problem is i can't extract or make a bootable disk of thaat .img file
i tried the dd command, but i dont think i am using it right.
here is exactly what i have been doing:
droped SUSE.img in /tmp
mounted the floppy drive
dd if=/tmp/SUSE.img of=/dev/fd0h1440

thanks in advance

what's your blocksize and blockcount?

try adding 'bs=1k count=1440' parameters.

IOW, try "dd if=/tmp/SUSE.img of=/dev/fd0 bs=1k count=1440"

oh, and since you're writing directly to the device: do not mount it
beforehand. umounting a mounted filesystem causes stuff to be written to the
filesystem. you don't want this. you want only the bytes from the SUSE.img file
written to the floppy disk and none other.
