#66 Not booting from floppy / HDD after bootrom

version 5.4.0, NIC: 3C905-TX.
In the configuration I've chousen BOOT_NIC,
BOOT_DISK and BOOT_FLOPPY options, when
bootrom code starts it displays a menu with options to
boot from net, floppy and HDD, when I chouse to boot
from floppu or HDD it displays "Probing bla-bla-bla", but
does not boot. Booting from net is working.
