chcem nahdar do RB112 firmware cez netinstall, ale nechce mi to ist

(na inych RB mi tento postup fungoval)
pri boote standartne nastavim boot options na Ethernet, a v netinstall nastavim Net booting, ale cez hyperterminal vidim nasledujucu hlasku...
Kód: Vybrat vše
RouterBOOT booter 2.4
RouterBoard 112
CPU frequency: 175 MHz
Memory size: 16 MB
Press any key within 2 seconds to enter setup..
kernel not found
trying bootp protocol.... OK
Got IP address: 10.1.1.77
resolved mac address 00:13:20:CA:13:1F
transfer started ....................... transfer ok, time=7.51s
setting up elf image... OK
jumping to kernel code
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
a dalej sa nepohnem, vie mi s tym niekto pomoct, alebo aspon povedat ako ozivim toho smejda?
