Re: [coreboot] ASUS M2V problems

It's complicated and dependent on the chipset. There is no general answer to how or whether VGA will or won't work. You can thank the chipset makers for this situation :-) ron

This seems strange to me. Besides, I've got the Coreinfo payload working when trying out Coreboot in Qemu, so obviously there's some VGA code somewhere that works at least when the Coreinfo stage has been reached, but I still get nothing when flashing Coreboot onto my bios chip. > When you use FILO as a payload, your key-presses may be detected like > ESC button though i did not test it myself but I found some keyboard > manipulating code.... > > > On Mon, Apr 23, 2012 at 5:16 PM, G <tjmadwja(a)gmail.com> wrote: >> On Mon, Apr 23, 2012 at 12:33 PM, ali hagigat <hagigatali(a)gmail.com> wrote: >>> You'd better buy a debug card and plug into the PCI slot and see what >>> numbers it will display.

As far as I know Coreboot can not drive VGA and monitor by itself. There is not enough code to do that and nothing is displayed on monitor when you run Coreboot only. It only sets up some parameters regarding to VGA which will be used by Linux kernel later. When you use FILO as a payload, your key-presses may be detected like ESC button though i did not test it myself but I found some keyboard manipulating code....

More elaborate commit messages
by Paul Menzel 28 Apr '12

28 Apr '12

Dear coreboot folks, it is great to see all the patches sent, reviewed and committed to the list. Could the commit messages please be more elaborate? In my opinion it would not only help review and prevent possible breakage, it is in my opinion even more important for new contributors and later bug or regression hunting. I am well aware that it takes more time to write nice and elaborate commit messages like for commit 751508ab [1]. But it is worth it in the long term to know what the problem was, how it was fixed and how it was tested. In addition since our Wiki lacks some pages on supported boards and some areas are not that up to date, it is important to document a certain working state in the commit message. So if new boards are added, it would be great, to have more information about this board. An URL to a Web site with more information, what payload was used, what operating system was tested, what did work and what did not and how long did it take coreboot to execute. This would also make it easier for journalists and non-developers to write up articles including blog posts about new developments in the coreboot project. Thanks, Paul [1] http://review.coreboot.org/gitweb?p=coreboot.git;a=commit;h=751508ab019e061…

Patch merged into coreboot/master: 8e0e8bc Reverse Vendor ID & Device ID for map_oprom_vendev()

the following patch was just integrated into master: commit 8e0e8bc705bcf1394c1b0e2fb2144f08fada8803 Author: Martin Roth <martin(a)se-eng.com> Date: Thu Apr 26 16:04:18 2012 -0600 Reverse Vendor ID & Device ID for map_oprom_vendev() - When calling map_oprom_vendev() the vendor ID and device ID are joined into a 32 bit value. They were reversed from the order that I would have expected - Device ID as the high 16 bits and the Vendor ID as the low 16. This patch reverses them so so that the the dword comparison in map_oprom_vendev() matches what's entered into Kconfig for vendor,device. - Change files calling map_oprom_vendev() Change-Id: I5b84db3cb1a359a7533409fde7d05fbc6ba3fcc4 Signed-off-by: Martin L Roth <martin(a)se-eng.com> Build-Tested: build bot (Jenkins) at Fri Apr 27 17:42:40 2012, giving +1 Reviewed-By: Stefan Reinauer <stefan.reinauer(a)coreboot.org> at Fri Apr 27 21:58:47 2012, giving +1 See http://review.coreboot.org/938 for details. -gerrit
