I've put the board's original BIOS in the RD1 and am writing > to the SST 39SF020A instead, which works without problems. I've read posts about the RD1 that suggest its integrated flash device is low quality and it may take 10 or more flash attempts to get a good flash update to the RD1 flash device. As a result, many RD1 BIOS Savior users will flash the commercial BIOS image (or other known good BIOS image) into the RD1 integrated flash device as many times as needed to get an image that boots. Then use the original BIOS device to flash test BIOS image (usually LinuxBIOS images among this group), since the original BIOS device usually flashes OK on the first attempt. I've used the RD1 in the above fashion with great success on the Tyan S2885 mainboard. The same RD1 would not work on the nVidia CK8-04 CRB mainboard. I think the CK8-04 CRB requires a flash device that the RD1 does not support. However, the RD1 worked well as an "do nothing" adapter which allowed swapping the BIOS flash device between my flash burner and the mainboard without any wear to the mainboard's BIOS socket. BTW, my flash burner is an older Enhanced Willem Universal Programmer. I got mine for only $60 US over a year ago. I've seen it for less than $40 on eBay a few weeks ago. The newest model is going for about $50 US. It does a LinuxBIOS flash in about 5 minutes; not bad for a $60 burner. However, it does require changing DIP switches to match an image for each device it can program. Great for the amateur or professional with a small budget. > > BTW, a cable of your RD1 is not broken? > > I needed soldering to fix it. > Mine was fine out of the box. Mine cable and switch worked fine out of the box as well. Sincerely, Ken Fuchs <kfuchs(a)winternet.com> ami-mac-sun

[LinuxBIOS] LinuxBIOS support for nvidia CK804 northbridge?
by Carl-Daniel Hailfinger 19 Apr '06

19 Apr '06

Hi, in the process of trying to find any motherboard with more than 3 PCI-Express slots and LinuxBIOS support, I failed miserably. It seems such boards only exist with nVidia CK804 northbridges for which I couldn't find any code in the LinuxBIOS source code. Section 2.9 of the LinuxBIOS FAQ suggests to send lspci -vvv to this list for closer inspection. One of those systems with 4 PCIe slots is the Asus K8N-SLI Deluxe. The lspci below contains four PCIe gigabit ethernet controllers at 0000:01:00.0, 0000:02:00.0, 0000:03:00.0 and 0000:04:00.0. It's the only motherboard with this northbridge I have access to at the moment. switch:~ # lspci -vvv 0000:00:00.0 Memory controller: nVidia Corporation CK804 Memory Controller (rev a3) Subsystem:

[LinuxBIOS] bus 0 dev 0 and fidvid change
by Lu, Yinghai 04 Apr '06

04 Apr '06

Please check the issue 41, I make K8 MB can be compiled, and It include bus0/dev0 and fidvid change enhancement HT_CHAIN_UNITID_BASE Default is 1, and if it is 6, then amd8131 will be from 6, also if it is 0, will assume ht chain only have one HT device... HT_CHAIN_END_UNITID_BASE Default is 0x20 --- mean do not use that, if it is 0, the amd8111 will be dev0 SB_HT_CHAIN_UNITID_OFFSET_ONLY Default is 1, so if HT_CHAIN_UNITID_BASE!=1, will only offset unitid of SB CHAIN. K8_SB_HT_CHAIN_ON_BUS0 Deault is 0, if it is 1, will put sb chain on bus 0, even for S2885 sb ht is on link2, it will put on bus0. K8_SET_FIDVID in cache_as_ram_auto.c or auto.c Fidvid change to sync the fid on 4 way or more system with different cpu installed.... Put following sequence in your cache_as_ram_auto.c after ht is set. enable_fid_change(); enable_fid_change_on_sb(); init_fidvid_bsp(bsp_apicid); please check init_cpus.c and fidvid.c and amd8111_early_ctrl.c for detail....

[LinuxBIOS] VIA EPIA-ML6000EA VGA Problem and Kernel Panic
by Daniel Parthey 04 Feb '06

04 Feb '06

Dear List Members, I tried to get LinuxBIOS Rev 2163 running on an VIA EPIA-ML6000EA Board using the EPIA-M target. The kernel is on /dev/hda1 of an IDE harddisk. After building the rom image vgabios+linuxbios[filo] I did the following: Boot factory BIOS Remove BIOS chip Insert Test chip Write linuxbios.rom image to flash Reboot, it booted, network worked, but vga output failed Reboot, it booted, network worked, but vga output failed Switched off power Switched on power Graphic output totally fails and kernel panic occurs, my LinuxBIOS.rom does not boot on its own anymore. Maybe this has something to do with the VGA Bios, but I don't know what the reason could be? I extracted the VGA Bios from the running system with original BIOS with the following command and get an video.bios.bin with the 55 aa in the first two bytes: dd if=/dev/mem of=/video.bios.bin bs=65536 count=1 skip=12 At some other location I read something about other weird dd parameters. The resulting vga image from /dev/mem looked as follows: $ ls -l video.bios.bin -rw-r--r-- 1 pada pada 65536 2006-01-23 10:31 video.bios.bin $ file video.bios.bin video.bios.bin: BIOS (ia32) ROM Ext.

I hacked the Makefile to prepend vga.bios.bin to the bios image (as described in the VIA EPIA-M howto) Now I get a kernel panic with the following output on ttyS0 and the system hangs. And Ideas what I could try to prevent the kernel panic? Here's the full console output from null modem connection on ttyS0: LinuxBIOS-1.1.8.0Fallback Mon Jan 23 11:24:51 CET 2006 starting...

[LinuxBIOS] Fwd: [Linux-fbdev-devel] [patch] Framebuffer driver for Geode GX
by Richard Smith 01 Feb '06

01 Feb '06

This may be of interest to some people working with the Geode GX ---------- Forwarded message ---------- From: David Vrabel <dvrabel(a)arcom.com> Date: Jan 31, 2006 12:19 PM Subject: [Linux-fbdev-devel] [patch] Framebuffer driver for Geode GX To: linux-fbdev-devel list <linux-fbdev-devel(a)lists.sourceforge.net> A framebuffer driver for the display controller in AMD Geode GX processors (Geode GX533, Geode GX500 etc.). Tested at 640x480, 800x600, 1024x768 and 1280x1024 at 8, 16, and 24 bpp with both CRT and TFT. No accelerated features currently implemented and compression remains disabled. This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS) has created an appropriate virtual PCI header.

[LinuxBIOS] IWILL DK8-HTX
by Philipp Degler 31 Jan '06

31 Jan '06

Hi greg, coming back on your thread-entry. We would like to get the IWILL DK8-HTX Rev. 1.0 running. Is it possible to use devbios or mtd to access the bios or is the hardware flash programmer the only possible (better) way? The board uses an AMIbios, SVR 2000, AA46 (6827) with the following layout: (x7) , , , , , , , - - - - - - - - - - (x9) - - - - - - - - , , , , , , , What hardware flash programmer would you suggest to get started? thx a lot -- phil On Fri, Dec 09, 2005 at 08:24:34AM -0600, Young, Jeff wrote: > > > I see that the Iwill board dk82s is supported?

I am merely proposing to mod the standard LinuxBIOS makefile so that the ldscript.ld is not a sequence of INCLUDE statements, but instead a sequence of ld commands. (Sorry, folks, I have not done this yet) What you did is hack the ldscript.ld script to make things fit. This is going to burn you big time next time you need to run buildtarget -- you will lose those changes. You need to set proper options in your targets/tyan/s2895/Config.lb -- for best results, however, make your own copy of that file. Please see my linux journal web article, wherein the way you size rom images is explained. Sorry you are having trouble, we are looking at this board too and will try to make sure it works. thanks ron

[LinuxBIOS] tyan s2895 build question - again
by Young, Jeff S. 27 Jan '06

27 Jan '06

Howdy again, Things are getting better now, so I wanted to keep everyone up to date with what I had To do in order to get as far as I have. System: Tyan s2895 with 2 Dual Core AMDs and 8GB memory BIOS: Using RD1 Bios savior (4mbit) OS: Linux - SuSE 10.0 stock (ie, gcc 4) Build issues: when building, there was an overlapping section. I created the following Section and it fixes it: .rodata. : { *(.rodata.str1.*); } This was placed after .rom section Payload not found. It wasn't clear from the writeup that I had to get the Payload from the web site. Stefan was an immense help in this arena. Maybe the payload directory should be bundled with the snapshots because You need it anyway. Run issues: I build the s2895 bios (fallback and normal) and flash the RD1. I don't know If the fact that the RD1 is 4mbit and the original chip was 8mbit will cause any Problems. The BIOS starts up just fine until the time comes to enable the cache The second time around. (This is after the device enumeration and is in the Initialization stuff.) It hangs right after the code gets cr0 to update it. I get the impression that I am the only one seeing these issues. It seems that everyone else Can just build and run. Is this really true? If you just grab snapshot 2163, untar it, and buildtarget tyan/s2895 Cd tyan/s2895/s2895, and make, it does it just fine??? Any ideas on the cache enable? Thanks, Jeff

It builds fine here, see build log http://snapshots.linuxbios.org/stats/abuild-LinuxBIOSv2-2163.log Your gcc might make things larger than gcc 4 which is why you saw the overlap error. increasing ROM_IMAGE_SIZE(?) should help without changing the LD script. Also I am pretty sure you get your image compiling when you fix your payload path above.. Stefan
