bootable USB drive

Hi,
I am trying to install OpenWRT image on bootable USB thumb drive. I have kernel+ext2 fs image:
"openwrt-x86-2.6-ext2.image" ,
The thumbdrive is formatted to vfat, the device for it is "/dev/sdb1", but when i try:

dd if=openwrt-x86-2.6-ext2.image of=/dev/sdb1

seems like everything is removed from thumbdrive, but but nothing is installed. No errors...
Any idea what the problem might be?
Thanks,
-v

You don't need to format the drive if you overwrite it with dd. Try it with /dev/sdb instead of /dev/sdb1.

There is your fix. I'd put bs=6M at the end.

I kind of doubt the block size would fix it. I agree that you are not using a block device correctly. The sdb wouldl be my choice. (better be sure of that)

See this maybe.
