someone report to me that www.linuxbios.org is down. You'd better to direct them to wiki.linuxbios.org in the page. YH

don't need, 1. good hw design should use one serial EEPROM to store MAC address, So when flash the BIOS, the EEPROM is still there. in ck804_nic.c will read MAC from serial EEPROM in SMBUS (bus num and device num is set in Mainboard Config.lb), at first. 2. even for bad design, you can keep your own romstrap.inc/lds in your mainboard dir, and modify Config.lb to point corrent file. In such case, you need special flash util to keep your MAC address or read the MAC address at first, and then set it back.... YH > -----Original Message----- > From: Ronald G.

Your approach only allows the MAC address to be in the EEPROM or the romstrap. Every motherboard would have to put the EEPROM in exactly the same place for this to be a general solution. Not likely. Neither place is a general solution. Getting the MAC address is board specific and belongs in mainboard.

[LinuxBIOS] CK804 suggestions
by Stephen.Kimball＠bench.com 17 May '05

I'd like to suggest that the romstrap files be moved from southbridge to mainboard, because the files are board specific with a default MAC address. Also the ck804_nic.c files needs a mainboard specific get_mac_address() that resides in mainboard. Steve

K9? I can not find the doc in NDA section.... Quad core? I guess current only tie-1 can have some sample....

[LinuxBIOS] About Nvidia chipset support
by YhLu 17 May '05

17 May '05

All, Finally I get the approval for releasing Nvidia chipset support for Ck804. I hope end user to press nvidia to release more info to make sata and on die lan work. The problem my code is messed up dual core support etc. I need some time to split them up. I will commit soon about Nvidia CK804 support smbus bus number support (to handle multi sumbus and mux) superio smsc 47 support Tyan S2895/S2891/S2892 support flash_rom Ck804 support maybe two months later after AMD issue auth letter or put dual core on public AMD D0/E0 Opteron new mem mapping support AMD E Opteron dual core support AMD E Opteron mem hole support AMD K8 Four Ranks DIMM support Regards YH

[LinuxBIOS] EPIA result
by Jun OKAJIMA 16 May '05

16 May '05

Here is my result of current LinuxBIOS. And still does not work. Do you have any advice? Especially, lx1 / epia would run with very little effort, I suppose. What I have missed? BTW, I even have not got EPIA-M with VIA fast boot util running. Why? any advice? I used a single-bank 128 MB DDR-266 DDR RAM which the doc assigns and tried both BIOS_R and BIOS_D, but even debug messages from a serial port do not come. --- Okajima, Jun. Source: freebios--devel--2.0--patch-30.tar.bz2 freebios--devel--1.0--base-0.tar.bz2 Payload: filo.elf with USB from Etherboot-5.4.0 M/B: EPIA C800 with 128M SDRAM on slot0 and 512M SDRAM on slot1. EPIA MII 12000 with 128M single bank DDR. both are confirmed to work in Linux and Windows. mems are checked with memtest86 and no problem. result: lx1 / epia -> can not load a payload. maybe I missed something? lx1 / epiam -> can not recognize SDRAM. lx2 / epia -> stuck with MTTR stuff. lx2 / epiam -> can not build.
