AWWWW Crap!
by Adam Talbot 09 Dec '04

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 ?
by Arun 07 Dec '04

07 Dec '04

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.

Can any one give the the difference between the VIA Northbridge's vt8601 and vt8604. Will the code from the vt8601 be able to boot the vt8604? -Adam Talbot

epia problem
by Luc Belliveau 06 Dec '04

06 Dec '04

I compiled from freebios2 from cvs, when I boot all I get back from the serial port is: LinuxBIOS-1.1.7.0Normal <date> starting.. vt8601 init starting Slot 00 is SDRAM 04000000 bytes x2 Slot 01 is empty Slot 02 is empty Slot 03 is empty vt8601 is done 0 that's it. I tried changing the DEFAULT_CONSOLE_LOGLEVEL but when I do that the resulting rom stops at Slot 00 is SDRAM 04000000 bytes x2. I can't add uses DEFAULT_CONSOLE_LOGLEVEL or option DEFAULT_CONSOLE_LOGLEVEL in the Config.lb file either, the buildtarget scripts shuns it. I'm using FILO as the payload, with no vga bios yet. Could it be a FILO problem? I've never seen linuxBIOS before yesterday so I don't know what should be appearing on the terminal.. Any assistance would be appreciated :) Luc

jump to boot code
by Gin 06 Dec '04

This is the message I got in the end. Linuxbios tries to load the ELF image. It seems that there are 2 segments in the ELF. In the end, linuxbios jumps to an entry that looks like the in the middle of the first segment. Does it look right? The FILO.elf doesn't seem to load succeffully.
