booting debian-installer b2 from usb memory stick

[lloyd <subscr002@twilight-systems.com>]

having some trouble booting di-b2 from a 128MB usb memory stick.  i did 
the following:

- downloaded hd-media-image.img
- dd if=hd-media-image.img of=/dev/sdb1
- install-mbr /dev/sdb
- changed first boot device to USB-ZIP

though hd-media-image.img is about 128MB, i only see about 3.3MB on the 
stick:

# cd /mnt/tmp2
# du -hs *
2.0K    disk.lbl
2.0K    f1.txt
2.0K    f10.txt
2.0K    f2.txt
2.0K    f3.txt
2.0K    f4.txt
2.0K    f5.txt
2.0K    f6.txt
2.0K    f7.txt
2.0K    f8.txt
2.0K    f9.txt
2.5M    initrd.gz
8.0K    ldlinux.sys
708K    linux
2.0K    syslinux.cfg
2.0K    syslinux.txt

i did try booting anyway - the little red light on the stick blinks like 
crazy as if it's being accessed, but nothing happens.  i gave it about 
ten minutes then rebooted.


any suggestions?
