[LinuxBIOS] Nvidia MCP55 support
by Lu, Yinghai Aug. 29, 2006

Aug. 29, 2006

I'm working on MCP55 support. There is some blank in mcp55_early_setup.c, So Current Only IDE and USB are working but the sata/nic/pcie don't work. There is another option is use Nvidia binary code (NVMM) directly. So questions is nvidia would allow AMD to release NVMM binary to LinuxBIOS. .., Is it ok to LinuxBIOS? Does is voliatiote the GPL?. Because this code will be called by LinuxBIOS. And it is not loaded and started by LinuxBIOS. (cpu microcode patch code and scsi firmare is loaded and started by LinuxBIOS but setting some register). Is VSM loaded and started only for OLPC? Thanks Yinghai Lu

Some SB need special setting about LPC decoding on PCI conf space.

This has the potential to get quite a lot of people started and getting any output at all is a major motivation factor even if the rest of the code for bringup has yet to be written. Can we build a ROM which does nothing but execute early serial code for a given SuperIO, prints a few messages and then halts? So that if somebody knows the SuperIO on his mainboard he can build a ROM testing the code we have for it? Or does the early serial code also depend on northbridge/southbridge/CPU?

Re: [LinuxBIOS] Microkernel / Manufacturers

Will, The Edk2 project on www.TianoCore.org does not have silicon enabling code but it does implement UEFI conformant interfaces. It currently builds under Windows, Linux, and Mac OS X. So this code may be helpful to you. It's all BSD license so you can use it how ever you like. If you have any EFI questions you can use the mailing lists on www.TianoCore.org to get answers as a fair number of the people from United EFI Forum board of directors companies (AMD, AMI, Dell, HP, IBM Insyde, Intel, Microsoft, & Phoenix Technologies) and others hang out on these mailing lists. Of course www.UEFI.org lets you get the official UEFI info and latest versions of the specifications. I'm really excited about the future of EFI. The Intel based iMac in my office is a cool machine and it's really great to see the innovation Apple has done based on EFI.

Hello, I am currently involved into the UEFI project. I would want to build an Open Source UEFI firmware in the style of U-Boot/LinuxBIOS but to boot a microkernel. Which manufacturer could I contact to build a firmware ? ( to have the specs/datasheets of the hardware) If you want to contact me, my mail is guillaume_dot_fortaine_at_wanadoo_dot_fr I will set up a mailing-list, a web server, a wiki and an IRC Thank you for your answer, Best Regards, WIll

[LinuxBIOS] Booting LinuxBIOS on an EPIA-V
by Fredrik Tolf Aug. 26, 2006

Aug. 26, 2006

Hi list! I've been trying to get LinuxBIOS to boot on my EPIA-V motherboard (VIA 8601A NB, VT8231 SB), and at first I followed the bundled HOWTO for the EPIA-M, before I discovered that EPIA-V was an entirely different creatures (it uses SDRAM, whereas I believe that the EPIA-M uses DDRAM), and the EPIA-M BIOS didn't boot, of course. However, I've tried a number of different variations of the via/epia configuration now, and it doesn't seem to want to boot whatever I do. The new flash chip I used is a 512 KiB chip, as opposed to the original 256 KiB chip (which isn't a problem, though, because if I burn the original BIOS to it with a 256 KiB block from /dev/zero prepended to it, it boots just fine), so I tried the 512kbflash config file as well, but to no avail. I'm using FILO as the payload. I'm beginning to run out of options, and I don't know how to diagnose LinuxBIOS. The monitor doesn't turn on, so I'm guessing it might be something to do with the VGA BIOS. In the EPIA-M HOWTO it said to prepend the LinuxBIOS image with the original 64 KiB VGA BIOS image -- is that the same for the EPIA-V (and in that case, how would I do to generate a LinuxBIOS image that is suitable for prepending with the VGA BIOS)? Thank you for your time! Fredrik Tolf
