[LinuxBIOS] abandoning vt686a/amd75x, starting i815
by Corey Osgood 07 Dec '06

07 Dec '06

So far, with the FIC SD11, I've been able to get serial output ONLY after a soft reboot from the original BIOS (in other words, my initialization isn't working right). Also, SPD has been completely uncooperative (can't read the ram at all), and I just don't have the knowledge/tools to properly debug it. So, I'm leaving it for now and going to work on the i815 northbridge, as it seems there is at least _some_ demand for this, and the southbridge/superio are already very nearly supported (i82801ba, lpc47m102). Has anyone looked at this in the past and have any suggestions? Also, is there somewhere a generic rundown of what exactly needs to be done by the northbridge, and what functions are supplied by linuxbios already, or just doxygen? Thanks, Corey

Please wait one or two days. The usb debug cable should arrive my lab today.

If someone needs me to buy the motherboard and ship it to him in order to work on it, I'm willing to do that. Just let me know; we'd like to get this working quickly, if possible.

[LinuxBIOS] AMD PIC BIOS - Flashing on WinCE?
by ozcan＠ug.bilkent.edu.tr 07 Dec '06

07 Dec '06

Hello all, I have one of those AMD PIC Computers (Personal Internet Communicator). It has a Geode processor (x86). it comes with WIndows CE preinstalled and refuses to boot antthing else. I read on numerous places that there is some cryptographic handshaking going on between BIOS and the OS loader. Therefore at the moment I cannot boot it with Linux. And unfortunately the BIOS chip is soldered onto the mainboard. So my only bet is programming the chip with LinuxBIOS under Windows CE. Is this possible? I want it so bad, as this machine is garbage with Windows CE running. Thanks in advance.

[LinuxBIOS] C3 Lightning Talk abstract
by Peter Stuge 07 Dec '06

07 Dec '06

I'm going to C3 and would like to hold a LinuxBIOS Lightning Talk. See http://events.ccc.de/congress/2006/Lightning_Talks and http://www.guckes.net/cccc2006/lightning_talks.html We get five minutes. What do we want to say? I was thinking: (Please revise this list. :) * Describe what LinuxBIOS is and does, benefits and use cases off the excellent wiki welcome page. * Talk about payloads. * Mention OLPC. (But what are the important points?) * Show a demo. //Peter

[LinuxBIOS] vga bios troubles
by Jon Dufresne 07 Dec '06

07 Dec '06

I followed the guide at this site http://linuxbios.org/VGA_support to get my onboard video to work. I have yet to be successful. I am a little confused about the Config.lb section. This is what the guid says: device pci 9.0 on # PCI chip drivers/pci/onboard device pci 9.0 on end register "rom_address" = "0xfff80000" #512k image end end I don't get why you list the "device pci 9.0" twice. I tried that and when I did my vga device never got the driver from onboard.c, instead it would always get the generic pci driver. So I changed it to only include the device below the chip line. This is what my Config.lb looks like chip northbridge/intel/i855gm chip cpu/intel/socket_mPGA479M device apic 0 on end end device pci_domain 0 on device pci 0.0 on end # host bridge device pci 0.1 on end # memory configuration device pci 0.3 on end # process configuration device pci 1.0 on end chip drivers/pci/onboard device pci 2.0 on end # vga controller register "rom_address" = "0xfff80000" #512k image end chip southbridge/intel/i82801dbm chip superio/ite/it8712f end end end end One thing that is also strange is that when I run "lspci" in a working environment I see two vga devices one at 0:2.0 and one at 0:2.1, I tried listing both but LB complained that I had a leftover static device at 0:2.1, it appears that only one of these devices is visible at boot. So I continued with the code above, and in the debug output I can see where linuxbios attempts to run the proprietary vga bios. I see: PCI: 00:02.0 init rom address for PCI: 00:02.0 = fff80000 PCI Expansion ROM, signature 0xaa55, INIT size 0xc800, data ptr 0x0040 PCI ROM Image, Vendor 8086, Device 3582, PCI ROM Image, Class Code 030000, Code Type 00 copying VGA ROM Image from 0xfff80000 to 0xc0000, 0xc800 bytes entering emulator Now, 0xC0000 is controlled by my PAM registers, so I took my best guess and set it read/write to SDRAM. When I do this LB stays inside the emulator for a while and eventually kicks out with this message: halt_sys: file /root/LinuxBIOSv2/src/devices/emulator/x86emu/ops.c, line 4387 I never see anything on my monitor. I looked at the ops.c file but couldn't figure out what was going on. I have been fooling around with this for quite some time, changing every little thing I can think of, but no luck. My northbridge is an Intel 855 gme, I used the perl script to extract the vga bios which is 50KiB, I subtracted that size from the ROM_SIZE, and I concatenated it with the linuxBIOS. Anyone have an idea how to fix this? Thanks, Jon
