good to know.  but this bios iso seems pretty mysterious to me, i
downloaded it a second time, they compare equal, neither memdisk nor the
bios boot it, and ls doesn't even show anything, tho dir and type did (see
OP).

seems to have written properly.  both the iso itself, and /dev/sdb, appear
to be an iso9660 filesystem, both mount without error, but ls shows no
contents:

when i select USB HDD and hit enter, the screen goes blank for a half
second, shows no message, and simply shows the boot menu again:

Boot Menu
=========
 ATAPI CD0: MATSHITADVD-RAM UJ8E2
 ATA HDD0: SAMSUNG HN-M101MBB
 USB HDD: Generic Flash Disk
 PCI LAN: Realtek PXE B03 D00

i'm clueless...
