a question about hardware and PCI
by ali hagigat 10 Apr '11

10 Apr '11

I have a general question about a PCI-to-PCI bridge. If the device has a positive decoder and receives an address in the range of the addresses it should respond. Then it claims the address and forwards it to the secondary interface. Now suppose no target on the secondary interface claims the transaction and master-abort happens for the second interface. What will happen to the primary interface then? Why PCI specifications do not explain the connection between the state machines of the primary and secondary interfaces?

Help for motherboard
by sh4r4d＠gmail.com 10 Apr '11

10 Apr '11

Hi All, I wanted to build a new Desktop workstation with currently available CPU and motherboard that is supported by Coreboot bios, I have searched few links for it e.g. Ubuntu-certified hardware http://www.ubuntu.com/certification/ Zareason http://zareason.com/shop/home.php AMD Processors - Recommended Motherboards http://products.amd.com/pages/recommendedmbfilter.aspx?AspxAutoDetectCookie… But these site mention hardware where gnu/linux could run easily, but they do not inform about coreboot bios compatibility. And checked http://www.coreboot.org/Supported_Motherboards for searching suitable motherboard, seen coreboot related video in youtube. But I did not found here new Intel and AMD cpu for motherboards in Desktop/Workstation section (except Laptop) mentioned for e.g. Intel Core 7i Intel Core 3i and similar AMD's latest. So finally I like to know do these newer CPU's any motherboard going to be supported in near future, So I will purchase that motherboard. I want to find it out as it will be difficult to change hardware than software later. Please suggest which CPU/motherboard combination is good with coreboot. -- Regards, -sharad

[PATCH] i945: improve get_top_of_ram()
by Sven Schnelle 09 Apr '11

09 Apr '11

The current version doesn't honor TSEG, and fails to report the correct top of RAM if IGD is disabled. This is because it uses the BSM (base of stolen RAM) register. In that case, we should use the TOLUD register.

e-vectra flash
by Devel 09 Apr '11

09 Apr '11

Hello, (Murphy's Law in action!) Well, I tried to use Coreboot + Seabios in old hp e-vectra. - Download coreboot. - Compile coreboot. - Flash with flashrom. Seems to be that is not easy, because old e-vectra do not boot. Any page that explains how to add devices like onboard vga, and onboard ethernet to image? Any pre-builded rom for this device? I will try to re-flash using eeprom programmer. Regards, -- Ordenadores, componentes y software: http://www.1pc.es/ Sistemas IT: http://www.precioventa.com/
