Yeah, floppy goes clich clich clich and the light comes on (I've done mis-called the device name before so I tripled checked that).
I also did an fdformat /dev/fd0u1440 and an fdformat /dev/fd0 but neither worked.
I've also tried re-specifying how the image is to be written to the floppy with:
dd if=/mnt/cdrom/boot/modules4 of=/dev/fd0 bs=32b
and I also tried
dd if=/mnt/cdrom/boot/modules4 of=/dev/fd0 bs=8k
and also
dd if=/mnt/cdrom/boot/modules4 of=/dev/fd0 bs=2x80x18b
But none of that worked either.
Is there some order you in which you need to load the drivers?
