[LinuxBIOS] Random Bios Postcodes after 0x88 with 440BX
by roger 09 May '07

09 May '07

Using a PCI Bios Postcard here and seeing some random Bios Postcodes. clipping from LinuxBIOSv2/documentation/POSTCODES: ---snip--- 0x10 Entry into protected mode 0x01 Entry into 'crt0.s' reset code jumps to here 0x11 Start copying LinuxBIOS to RAM with decompression if compressed 0x12 Copy/decompression finished jumping to RAM 0x80 Entry into LinuxBIOS in RAM 0x13 Entry into c_start 0xfe Pre call to hardwaremain() 0x39 Console is initialized 0x40 Console boot message succeeded 0x66 Devices have been enumerated 0x88 Devices have been configured 0x89 Devices have been enabled ---snip--- I don't know if the above are listed in an order that states these postcodes should be reported on the device or any order, but I do get the following reported on my postcard in order: 0x80, 0x88, E7 0x80, 0x88, 27 0x80, 0x88, A1, AC (Notice the 3rd and 4th post_code reported appear random.) Back Ground Info: I'm using the s1826 target with a 440BX board that has a Winbond w83977tf SuperIO chip. So I made the following changes for supporting the SuperIO W83977EF-AW chip. LinuxBIOSv2/src/mainboard/tyan/s1846/auto.c ---snip--- /*#include "superio/nsc/pc87309/pc87309_early_serial.c"*/ #include "superio/winbond/w83977tf/w83977tf_early_serial.c" /*#define SERIAL_DEV PNP_DEV(0x2e, PC87309_SP1)*/ #define SERIAL_DEV PNP_DEV(0x3f0, W83977TF_SP1) ---snip--- (w83977tf is an earlier model of the w83977ef-aw chip but appears very similar layout, if not, the same with minor fixes or updates.) >From what I'm guessing, superio devices are configured by the 0x88 post_code, but enabling the devices fails??? -- Roger http://www.eskimo.com/~roger/index.html Key fingerprint = 8977 A252 2623 F567 70CD 1261 640F C963 1005 1D61 Wed Apr 25 19:26:00 PDT 2007

[LinuxBIOS] Flashrom --layout fails badly
by Jeremy Jackson 08 May '07

08 May '07

If it can't open the layout file, it just goes ahead and flashes the whole part. Perhaps what the user (not naming names here) would prefer is for it to print an error message and stop. Just writing an email so I don't forget. -- Jeremy Jackson jerj(a)coplanar.net Email/Jabber/Google Talk/MSN (519)489-4903 Coplanar Networks http://www.coplanar.net

[LinuxBIOS] winflashrom architecture (Windows port of flashrom) -- looking for suggestions
by Darmawan Salihun 08 May '07

08 May '07

Hi all, I'm currently working on a windows port of the flashrom utility. I have been thinking about how it should be done. There are two paradigm that I'm thinking about as of now. I need your suggestions/critics, etc. ;-). Both of them based on the fact that this utility should be divided into user mode code and kernel mode code. 1. The kernel mode code a.k.a kernel mode device driver is as simple as possible and only provides "raw" functionality, i.e. capability to map the physical address space in which the BIOS chip is mapped into the requesting user mode code. This approach provides the user mode code similar to mmap() function in *NIX. The pros in this approach is there won't be much changes to the *NIX version of flashrom to adapt it to windows and it will be a little easier to develop because no need to load/unload the driver. The cons is if the user mode code went wrong, it can bring the whole system down. I've been experimenting with a minor tested version for this approach though. 2. The kernel mode driver implements the majority of the flashrom code and the usermode code is merely a "front-end" to the kernel mode device driver which provides all of the chip related logic. The pros in this approach is the code would probably much stable because the user mode code won't bring the system down as easily as the previous approach. The cons is it will very probably requires more work to port the *NIX version of flashrom to Windows with this approach and more over, I haven't been able to figure out how to do integrity-testing to the driver to ensure its stability :-(. Anyway, I'm also thinking about a quite "universal" interface between the user mode code and the kernel mode code. Perhaps a well defined interface that will work both in *NIX and Windows in the future will be needed or maybe I will try to provide an "evolution path" to such an interface. I really need suggestion in this area. --Darmawan

[LinuxBIOS] set fiv fail

Hi all, I got an error message from linuxbios as below: The CPU on my platform is Sempron. Why do I get “set fid failed for apicid =00” and how to solve this issue?? On the other hand, I got error message as follow: Ram2.00 No memory for this cpu I have no idea how to solve this issue. Can somebody give me a suggestion how to find the bug out??

[LinuxBIOS] ECS top hat flash - dual-bios-circuit useable elsewhere ?
by Quux 07 May '07

07 May '07

I just managed to get my hands on a top hat flash. it is an empty plcc32 socket to flip over an soldered in flash chip. attached to the socket is a secondary flash mem and some circuitry to handle the "chip enable" signal, i.e. pull down the primary one and daisy chain the data/addr bus. now I wonder, whether it is risky to use it on a non Elitegroup mainboard and it might brick a mobo with no matching circuitry. Ideally, I hope it works on a Gigabyte M57. should I give it a go ? --Q

[LinuxBIOS] Televideo TC7020 successfully booted with LinuxBiosV2
by Kenji Noguchi 06 May '07

06 May '07

Hi, I bought a TC7020, Windows CE.NET based thin client terminal for $10 about a week ago, and wanted to make it a car-puter. http://www.televideo.com/TeleVideo/TC7000_WinCE_Series.htm The box uses NS Geode GX1 CPU, PC97317 Super I/O, CS5530A south bridge, DP83815 NIC, and SST 29EE020 BIOS chip. I noticed the system configuration is very similiar to eaglelion/5bcm, and wanted to see how far it goes with unmodified configuration. I chosed Etherboot as payload, it just booted as if the 5bcm and TC7020 was identical box. Thank you for the great software! Kenji Noguchi

[LinuxBIOS] EPIA patch to fix non working IDE, with sigin off
by Ben Hewson 04 May '07

04 May '07

patch to fix the IDE configuration on EPIA boards. At some point this broke and stopped FILO from being able to boot. The fix is a simple one line change plus a comment to src/mainboard/via/epia/auto.c to write to the IDE configuration register 0x42 . This has always been done here, however at some point something broke it. The same register was also being set correctly in ide_init(), however for some reason this does not work. Possibly the register needs to be set before the IDE peripheral is enabled or maybe it is a timing issue. The section of code in ide_init() ( src/southbridge/via/vt8231/vt8231_ide.c ) that does write to register 0x42 has been commented out as it is superfluous and I have added a comment to indicate the reason, should someone at a future date wonder why. I have also changed the default COM speed from 19200 to 115200 in src/mainboard/via/epia/Options.lb There has been mention before about the EPIA board not being able to use 115200 but I have seen no such problems with my board.

[LinuxBIOS] [PATCH] flashrom patch for iwill dk8_htx
by Mondrian Nuessle 04 May '07

04 May '07

The attached patch enables flashing on the Iwill DK8-HTX board. Basically, it configures the SuperIO to set the right GPIO pins, so write protection is disabled. Signed-off-by: Mondrian Nuessle <nuessle(a)uni-mannheim.de> --- So, this is the second try :-) Only pci vendor id/device id is given, no subsystem id. Therefor, flashing when booted from factory BIOS will only work, if -m iwill:dk8_htx switch is given. I guess this could go in the wiki doc to this board...
