[LinuxBIOS] [PATCH] Reimplementation/fixing of CS5530/CS5530A southbridge code
by Uwe Hermann 16 Aug '07

16 Aug '07

See patch. This is also required to make the JUKI-511P code work AFAICT (won't build otherwise). Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

[LinuxBIOS] #78: Implement larfs to handle GRUB2 modules in flash easily.

#78: Implement larfs to handle GRUB2 modules in flash easily. ---------------------------------+------------------------------------------ Reporter: stepan | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Port GRUB2 to LinuxBIOS Component: code | Version: v3 Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ Implement a (simple) larfs driver in grub. Besides making it easy to solve the module loading itself, it would also help us - with copyright issues: if we port over the usb stack from FILO, it would not have to be part of the grub2 tree with all the efforts of getting it in there - with using grub2 as a 1st stage bootloader to load other payloads directly from flash, ie payloads that are in multiboot format rather than pure ELF. (I have XEN in mind) -- Ticket URL: <http://tracker.linuxbios.org/trac/LinuxBIOS/ticket/78> LinuxBIOS <http://www.linuxbios.org/>

[LinuxBIOS] GIGABYTE GA-M57SLI-S4
by Allix Davis 13 Aug '07

13 Aug '07

Hello, i bought a GIGABYTE GA-M57SLI-S4 motherboard after hearing LinuxBios works on it. I have not yet installed it, at the moment i am using the proprietary Award bios version F8 2007/03/20 . I wanted to use AMD-V with kvm or xen, unfortunately the bios has disabled it and there is no option in the bios to enable it. I found on a thread that before G stepping support disabling amd-v was difficult and therefore bios companies left it enabled. On a xen forum somebody had a Gigabyte M61P-S3 and had the same problem , they downgraded to a bios that did not have G stepping support and amd-v was enabled, of course they lost powernow and other features. I am asking if anyone knows if the latest bios version F9 or some way to enable amd-v on the bios, of course i am willing to use linuxBios , but i would like to wait for a few releases so all bugs are cleared and acpi is enabled. I have amd64 x2 5200+ on the board... kind regards Allix Davis

[LinuxBIOS] Filo + USB-OHCI boot
by Remy Bruno 12 Aug '07

12 Aug '07

Hello, It seems that the linuxBIOS mailing list also manages FILO, so I post this here, please let me know if I'm wrong. I'm trying to boot on an USB key using Filo and an OHCI host, but without success for now. I don't know if this is supposed to work (apparently yes). If not, is there a means to achieve USB key boot without the BIOS? Here is the description of the problem: USB key used: 0ea0:6828 Ours Technology, Inc. OTI-6828 Flash Disk Please not that this key boots right using the BIOS (but I would like to avoid using the BIOS), and is correctly recognized by linux (I noticed some similarities between the linux USB driver and the filo USB driver) PCI USB controllers (from lspci): 00:0b.0 USB Controller: nVidia Corporation MCP51 USB Controller (rev a3) 00:0b.1 USB Controller: nVidia Corporation MCP51 USB Controller (rev a3) Apparently, the host doesn't manage to give an address to the key (it tries 2, 3, 4, and so on, and reboots after a while).

I'm not familiar at all with USB, so I don't know how to debug this, nor what's wrong here. Note also that I'm using the regular BIOS of the MB (modified by adding an ISA ROM to the BIOS image, which contains FILO), and that I successfully boot using the IDE device. Any help would be much appreciated.

[LinuxBIOS] [PATCH] [ADLO] Booting Windows XP and Windows 2000
by Augusto Pedroza 06 Aug '07

06 Aug '07

We finally got windows XP to work with LinuxBIOS. Since it is working fine on qemu I hope more people can test it and understand it. Just few modifications to ADLO were necessary. see wiki for details: http://www.linuxbios.org/Booting_Windows_using_LinuxBIOS -- Augusto Pedroza

[LinuxBIOS] GA-M57SLI - Nvidia X Server
by john 02 Aug '07

02 Aug '07

Hello, I managed to boot LinuxBIOS on my M57sli MB but without X. I'm using the Nvidia proprietary driver. Here's the error message: (EE) NVIDIA(0): The NVIDIA kernel module does not appear to be receiving (EE) NVIDIA(0): interrupts generated by the NVIDIA graphics device (EE) NVIDIA(0): PCI:7:0:0. Please see Chapter 8: Common Problems in the (EE) NVIDIA(0): README for additional information. (EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device! Should I be using the free driver? My card is BFS8600GTS. Anybody have suggestions? John ==============

[LinuxBIOS] PIRQ REF DES AMD LXUVCRDK
by Otávio Alcântara 01 Aug '07

01 Aug '07

Hello to all, I'm porting a linuxbios v2 version for a board ref des LXUVCRDK ( http://www.amd.com/geodelxuvcrdk) based on norwich board. I've already got to boot linux from HD, but it seems to halt in some point (see log below captured from serial). Although, I'm using VSA (lx_vsa.36k.bin) and I got no output from video VGA. I'd like some help for setting up the PIRQ table and for VGA setup. PS: The schematics for this board are publicly available from AMD Embedded Developer Web Site.

[LinuxBIOS] [RFC] Use Linux MTD framework for SPI flash?
by Carl-Daniel Hailfinger 01 Aug '07

01 Aug '07

Hi! While thinking about adding SPI support to flashrom, I came across the directory linux/drivers/mtd/maps/ in a recent kernel tree and found drivers for flash on * Nvidia CK804 * AMD 76X * Intel ICHx Should we try to use the Linux MTD framework before hacking flashrom? If so, can somebody test? My machines either run too old kernels (production router) or the chipset doesn't appear in the list. Regards, Carl-Daniel
