[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] Trusted Platform Support for LinuxBIOS
by Mike Anderson 08 May '07

08 May '07

Greetings! I've seen a feature enhancement request for adding support for the TPM into LinuxBIOS. Is there anyone out there actually working on this? We have an Atmel TPM on an industrial motherboard and would like to help add this support to LB. Thanks, Mike

[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] supermicro/h8dmr port, vga
by Patrick McMurchie 08 May '07

08 May '07

Hi all, I have a few questions about the supermicro/h8dmr linuxBIOS port in specific, and the process for enabling vga support in general. Apologies if these questions are too noobish in nature. I can successfully extract the VGA ROM from a supermicro h8dmr-i2 using either /dev/mem with offsets obtained from /proc/iomem, or via amideco. Both methods yield files of the same size, but diff reports a difference. Since I wasn't sure about which one to use. I've alternately prepended both images to an appropriate linuxbios.rom. Regardless of which VGA ROM is used, the machine fails to boot (fans spin up for a moment, then stop, no serial or vga output) after I flash the resultant image. When configured to use serial console, without the VGA ROM, the system boots and works as expected. Something I've been wondering about is the "option ROM_SIZE" entry in the target's Config.lb: The VGA ROM is 44kB, and the SST Flash chip is 1024kB, but when I set ROM_SIZE to (1024*1024)-(44*1024) or 1003520, the final concatenated ROM weighs in at 1020kB, which flashrom will refuse to write. If instead I pad ROM_SIZE by 4kB, making it 1007616, I get a 1MB which flashrom will accept. Am I doing something silly here, or has anyone else seen this behavior? Per the VGA Howto, I've un-commented the appropriate device section in src/mainboard/supermicro/h8dmr/Config.lb, and enabled both CONFIG_CONSOLE_VGA and CONFIG_PCI_ROM_RUN in the target's Config.lb. Any help is greatly appreciated, thanks, Patrick.
