I have MS6178 ver 1.1, supported board, noted as not working on Linux. I can only get it working reliably with Knoppix although Debian Etch has worked intermittently. Embedded VGA... does that complicate things? I'm an intermediate user finding detail on the readme within Coreboot download difficult to understand. My chip is soldered and I'll have to reflash in situ, not worried about that because 1 without linux the board is useless 2 might be able to retrieve original image (which I have saved) from bootblock. Can I build the .rom on another box? Is there a way to build using a live cd or do I have to reinstall etch? And very important, is this too ambitious for someone who needs to ask these questions? Thank you.

s2892 Video card problems
by Myles Watson 09 Jul '08

09 Jul '08

All, The s2892 has on-board video. When I try to put a video card in the PCI slot I get the error: copying VGA ROM Image from 0xfd000000 to 0xc0000, 0xd000 bytes entering emulator Unexpected Exception: 2 @ 10:0000bf94 - Halting Code: 0 eflags: 00000006 eax: 000003ff ebx: 03000220 ecx: 00010733 edx: 000003ba edi: 0000c000 esi: 000ffff7 ebp: 0003db1c esp: 0003db1c The only thing I turned up was an old archive post which didn't help much. http://coreboot.org/pipermail/coreboot/2005-January/010362.html Does anyone know what the problem is? A pointer of where to look? Thanks, Myles

MS Windows XP Embedded via coreboot
by Ken.Fuchs＠bench.com 08 Jul '08

08 Jul '08

Is MS Windows XP Embedded bootable via coreboot? Has anyone actually tried to boot MS Windows XP Embedded via coreboot? --- I found a couple of coreboot Wiki pages that are relevant to the above questions, but neither provided any answer regarding XP Embedded. --- The ADLO web page: http://www.coreboot.org/ADLO The ADLO page doesn't mention MS Windows XP Embedded at all. This page doesn't seem to have been updated in years. I recall seeing messages on the list saying that people have been able to boot both MS Windows XP and MS Windows Vista. --- Booting Windows using coreboot: http://www.coreboot.org/Booting_Windows_using_coreboot This page is obviously more up to date and even links to the ADLO page. Thanks, Ken Fuchs

[PATCH] coreinfo: Add RAM Dump module
by Uwe Hermann 08 Jul '08

08 Jul '08

Hi, I've hacked up a small module for coreinfo which should be able to dump arbitrary RAM contents (in hexdump format). I'm using this to demonstrate the "cold boot" RAM attacks published at http://citp.princeton.edu/memory/, which works pretty nicely. Please review, it's possible that the code has some bugs, I'm short on time and didn't program very carefully.

v3 activity: all-time low
by Carl-Daniel Hailfinger 08 Jul '08

08 Jul '08

Hi, the statistics below are either a sign of v3 being completed or a sign of v3 being a neglected target. I find both of these scenarios rather frightening. What follows is the number of commits per month since the initial checkin. 1 2008-07 4 2008-06 15 2008-05 25 2008-04 21 2008-03 56 2008-02 28 2008-01 9 2007-12 24 2007-11 7 2007-10 16 2007-09 22 2007-08 38 2007-07 88 2007-06 42 2007-05 25 2007-04 110 2007-03 95 2007-02 12 2007-01 5 2006-12 18 2006-11 31 2006-10 Last month we reached an all-time low and it doesn't really look better for this month. I'll gladly review v3 patches if that helps. If anyone has pending v3 patches, please send them in. Regards, Carl-Daniel

flashrom: Winbond W83627DHG SPI, RDID 90, SST AAI & Intel D201GLY
by Peter Stuge 07 Jul '08

07 Jul '08

Patch attached. The wbsio driver has been tested by rphlx to work correctly for probe and read on the Intel D201GLY board, but erase and write was not tested since he had no easy recovery strategy in case of failure. If anyone can test erase, write or both on a board with W83627DHG or compatible (please add ids to wbsio_get_spibase()) I would be most grateful. Comments, as always, appreciated. //Peter
