Ok.
Problem cislo 1: nejede mi stara sitovka 3C900 na koaxu. Pres LiveDVD chodi. Ovladace jsou stejne.
Nemuzu ji ani restartnout nebo neco, v /etc/init.d/net.eth0 jaksi chybi :/

Using the default interface 'eth0'.
Basic registers of MII PHY #0:  0000 ffff 0000 ffff 0000 ffff 0000 ffff.
 The autonegotiated capability is 0000.
 No common media type was autonegotiated!
 This is extremely unusual and typically indicates a configuration error.
 Perhaps the advertised capability set was intentionally limited.
  Basic mode control register 0x0000: Auto-negotiation disabled, with
  Speed fixed at 10 mbps, half-duplex.
  Basic mode status register 0xffff ... ffff.
  Link status: established.
  Remote fault detected!
