Ron, I'd suggest changing busses[20] to busses[200] on line 290. My motherboard has a bus 128. It seems to run in 32-bit mode. Steve -----Original Message----- From: Ronald G.

I've just added the mptable tool from freebios1 to freebios2. It is in util. I am sending you a private copy in case you are 'cvs delay mode' ron

Ollie, it is worse than that, Gin needs to rewrite his mainboard config file. I am not sure what mainboard he has any more. ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

Hummm. Got both tomsrtbt and coyote Linux running. coyote Linux is very nice and I have other apps for it. But none of those had minicom on them.

AWWWW Crap!

OK, I have a bios chip that my flash ROM programmer cant program... The chip is a Amic A290021TL-70. OK, I would like to buy a new chip from a different manufacture. What do I need to keep in mind when I buy a replacement chip? Here is the data sheet from the off brand chip. http://www.amictechnology.com/pdf/A29002.pdf -Adam Talbot

RE: K8 D0 support

>Long term I wish we had a better way to handle development before the official >product launch. I think if I can keep pace with normal bios development, I can get updated detail info from vendor and our BIOS engineers. Otherwise they may forget some detail info and also some vendors may fail to update their datasheet. Then it may take some time to make Linuxbios work. YH

I am confused about what the current situation is. All I know for certain is that AMD has not updated their public documentation yet. So it does not appear as if these processors have been released to the public. Long term I wish we had a better way to handle development before the official product launch. Eric

Booting dos from freebios ?

Hi all, We have downloaded freebios 1.0 and we are trying to boot freebios on National Geode GX1 processor based system. We were successful enough to create a new target in freebios and boot freebios on the board with bios output on serial port . Also we tried to boot linux image minimal from freebios, but we are getting error saying error gunzip.
