No keyboard on startup?

hello

noticed wasn't able use keys during startup, trying reset pram. later on, when replaced standard 80gb harddrive bigger 1 , trying use "c" during startup, found out t can't use key during startup. learned firmware-password blocks keys during startup, except alt-option-f-o enter open firmware, can't enter open firmware during startup. mini doesn't respond key try use on startup. once booted, keyboard , mouse work both fine in snow leopard.

nothing. firmware-password protect machine unauthorized changes configuration, , does, you've found out.

assuming have administrator-account, can modify or remove password after booting machine.

open terminal, , type:

code:

sudo nvram -p

that prints list of variables stored in nvram, , should include line with

code:

security-password %70%61%73%73%77%6f%72%64

with ascii-table can decode (and your) password, way.

removing password:

code:

sudo nvram -d security-mode  sudo nvram -d security-password

when rebooting should able influence boot-process or access openfirmware.
