amd64: Problems with vfat fs?

Hi folks,

Is it possible that there is a problem with vfat on amd64? This is the effect I see:

I want to flash the BIOS of my PC, so I have to write a bootable DOS image on an USB stick and add the flash program and the new BIOS file:

cat DOS.img >/dev/sdd
mount -t vfat /dev/sdd /mnt
cp AWDFLASH.EXE FN85S235.BIN /mnt
umount /mnt

The USB stick boots, but if I run AWDFLASH, then nothing happens. It justs sits there and doesn't do anything.

But if I try this instead

cp DOS.img FLASH.img
mount -t vfat -o loop FLASH.img /mnt
cp AWDFLASH.EXE FN85S235.BIN /mnt
umount /mnt
cat FLASH.img >/dev/sdd

then AWDFLASH works as expected.

Kernel is 2.6.8, but I had problems with 2.6.7, too.

???

Could you check difference of those disks? Or could you send both images to me?

And please send dmesg and .config.

Thanks.
