hi all,

there are two questions on OpenFirmware:

i) what does this error or warning message mean:

'WARNING! MSSCR VALUES MIS-MATCH.' (IIRC followed by sth. like DEFAULT=20=

CATCH BLAHBLAH)?

ii) can i force re-flashing of the Power Mac's firmware?

the machine now has a new Sonnet Encore Dual G4/1,3GHz, before we tried=20=

a similar PowerLogix board, which turned out to be absolutely crap :(=20
however, PowerLogix req'd to install software and AFAIK it patches the=20=

Mac's firmware.

unfortunately, it doesn't patch the applied firmware's 'version'=20
information, that is one cannot determine whether _original_ Apple=20
firmware is loaded or a patched version -- furthermore, Apple's flash=20
utility seems only to check the firmware by its version, _not_ by it's=20=

checksum, so i have the following problem:

patched firmware says it's Apple's last for this machine -> Apple flash=20=

utility doesn't want to replace/flash it.

does anybody know how to get rid of this uncommon situation?

thanks in advance!

--=20
mit vorz=FCglichster Hochachtung/best regards,
