[LinuxBIOS] VIA EPIA build
by Jun OKAJIMA 02 May '05

02 May '05

Dont you have any suggestion? --------------- It would be sure that many guys in this list have succeeded to build a rom image for VIA EPIA series with both freebios1 and 2. How you did it? And what is the difference with my case? --- Okajima. ---------------- Hello Linux BIOS developers. I have tried to run linuxbios on VIA EPIA-C800 M/B, but failed. I tried both freebios1 and 2 src trees, but both failed, Sigh. Anyone can help me ? Source trees: freebios-20041019-1200.tar.bz2 freebios2-20050305-0000.tar.bz2 from http://snapshots.linuxbios.org/ in both case, I uses filo/usb from Etherboot 5.4.0 as a payload. FreeBIOS1: I tried with both util/config/epia.conf and epia800.conf, but both failed. epia.conf does not run. it shows weird and buggy chars. must be runaway. epia800.conf runs. but does not load a payload. just ended up with "bad gzip magic numbers" after had execed pc80/ide_* stuff. I looked up why epia.conf does not run and found the difference between both configurations. it would need these lines to be added, but why? option BOOT_IDE=1 option IDE_BOOT_DRIVE=0 option ONE_TRACK=63 FreeBIOS2: Just did not work. it seems not to work totally, because even VGA sync signal does not comes. BTW, how to enable VGA debugging output? --- Okajima, Jun. Tokyo, Japan.

[LinuxBIOS] Opteron memclk speed/loading fix
by Tao Liu 02 May '05

02 May '05

Hello, the following patch fixes memclk selection on different loadings for opteron, it is useful if you have more than 4dimms for one opteron cpu.

[LinuxBIOS] Committed GX1 code to V2 tree
by Hamish Guthrie 01 May '05

01 May '05

I have just finished committing my GX1 code to the V2 tree. There is still some work to be done (enabling shadow, and a few other odds and ends). I have tested this with etherboot only, so I have no idea what FILO will do - maybe someone would like to play with that! I also added my test target mainboard - this is an eaglelion 5bcm board, and is in src/mainboard as well as target. The Eaglelion board I have is a generic PC-style motherboard with the GX1 and cs5530 companion chip on it, as well as an NSC pc97317 super-io. It has no ethernet controller on-board, but I used a PCI ethernet card plugged into one of the 2 PCI slots it has. The SDRAM detection code in this version is robust and detects all the DIMMS I have been able to throw at it correctly. -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
