What has to be done to port to a new AMD board now? Its Nforce 4. Havent used linuxbios for a while as had to use Intel boards. Its Tyan S2865 http://www.tyan.com/products/html/tomcatk8e.html lspci is 00:00.0 Memory controller: nVidia Corporation CK804 Memory Controller (rev a3) 00:01.0 ISA bridge: nVidia Corporation: Unknown device 0050 (rev a3) 00:01.1 SMBus: nVidia Corporation CK804 SMBus (rev a2) 00:02.0 USB Controller: nVidia Corporation CK804 USB Controller (rev a2) 00:02.1 USB Controller: nVidia Corporation CK804 USB Controller (rev a3) 00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97 Audio Controller (rev a2) 00:06.0 IDE interface: nVidia Corporation CK804 IDE (rev a2) 00:07.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev a3) 00:08.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev a3) 00:09.0 PCI bridge: nVidia Corporation CK804 PCI Bridge (rev a2) 00:0a.0 Bridge: nVidia Corporation CK804 Ethernet Controller (rev a3) 00:0b.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:0c.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:0d.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:0e.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:05.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 01:06.0 FireWire (IEEE 1394): VIA Technologies, Inc.

[LinuxBIOS] Solaris
by Justin Cormack 06 Aug '05

06 Aug '05

Has anyone looked at what it would take to get Solaris booting under Linuxbios on Opteron? If not I might dig around (there is a modified grub - I think that does some of the init work; one suspects that because of its heritage it is quite BIOS-unencumbered). justin

[LinuxBIOS] First instruction in linuxbios
by Jorge Cardona 05 Aug '05

05 Aug '05

Hi. I'm new in this, and i'm reading the source and i have a question, which one it's exactly the first instruction that the processor execute when the pc is booting?, in which file is it? I don't complete understand the relationship between a normal bios and the kernel, i think that the bios it's has to pass some data to the kernel, if that's true ¿how exactly is that data passed to the kernel? In linuxbios, how it's this issue handle? PD: sorry for my english Thanks -- Jorge Eduardo Cardona jorgeecardona(a)gmail.com ------------------------------------------------ Linux registered user #391186 Registered machine #291871 ------------------------------------------------

[LinuxBIOS] Potential copyright issues with decompiling ACPI tables?
by Ken Fuchs 05 Aug '05

05 Aug '05

I haven't spend much time working with ACPI tables, but there may be copyright issues with decompiling these on a COTS BIOS and using the result in LinuxBIOS. Does anyone agree there may be a copyright concern here? I don't think there is, but I'm not a copyright lawyer. Sincerely, Ken Fuchs <kfuchs(a)winternet.com>

RE: [LinuxBIOS] util/getpir & util/mptable [Was "A boot problem...."]
by Stephen.Kimball＠bench.com 29 Jul '05

29 Jul '05

I think the words "make it dynamically" could be causing some confusion. I suspect YH doesn't mean you could run a getpir or mptable utility on Linux and get a good IRQ or MP table. I think YH means the mptable.c file will programtically build the mptable by looking for secondary busses. My experience has been that running utilities on Linux booted with a commercial BIOS does no good at all, because most BIOS's use ACPI tables. When ACPI tables are used, the get_pir utility will return an empty IRQ table, because all the IRQ table stuff is in the ACPI tables. You may be able to dump an mptable but it may also rely on ACPI stuff. So the best way to do it is manually like YH says. The IRQ table just needs the peer bus information and the MP table needs to match the bus configuration.

[LinuxBIOS] Is the MSI 694T Pro MS-6309 (v5.0) ATX mainboard supported?
by Marko Mäkelä 29 Jul '05

29 Jul '05

Hi all, I have built a personal video recorder using VDR and vdr-softdevice plugin on a MSI 694T mainboard running a 900 MHz Celeron. I would like to speed up the boot process: the BIOS needs over 10 seconds before starting LILO. I need the following features: - ATX wakeup timer - nvram-wakeup needs a reboot for the changes to take effect - wake-on-LAN (for starting the computer by the remote control unit bundled with the DVB-T tuner card; see my hardware hack at http://www.iki.fi/~msmakela/electronics/worc5/) - PCI, AGP and IDE (USB is not needed) Here's the lspci output: 0000:00:00.0 Host bridge: VIA Technologies, Inc.

The south bridge (next to the processor, I hope this is the correct terminology) is a VIA VT82C694T 0130CD TAIWAN 2IB0004361. The BIOS device is a PLCC chip with 9 pins on the long side and 7 pins on the short side. I can peel off the AMIBIOS label if needed.

I meant to say that booting a COTS BIOS & Linux and running util/getpir and util/mptable can be very useful in LinuxBIOS v2, but hand editing the results may be required. It would be nice, if util/getpir and util/mptable could be modified so hand editing the resultant irq_table.c and mptable.c would not be needed. This may not be very useful for experienced LinuxBIOS developers, but can save a lot of porting time for people who don't have as much LinuxBIOS or other BIOS experience.

Fwd: Re: [LinuxBIOS] Potential copyright issues with decompiling ACPI tables?
by Paul Millar 29 Jul '05

29 Jul '05

I guess we can all claim that IANAL, but I've seen similar arguments with wine that might be useful. Reading the copyright section on wikipedia: http://en.wikipedia.org/wiki/Copyright there's a mention of the "idea-expression dichotomy". From wikipedia: "a copyright covers the expression of an idea, not the idea itself [...]" For this reason, simple header files (*.h) are normally not considered copyrightable. See, for example: http://www.kerneltraffic.org/wine/wn20010219_83.html which links to the Sega case: http://www.eff.org/pub/Legal/Cases/sega_v_accolade_977f2d1510_decision.html If the copyright notice is in the BIOS binary, it applies to that instantiation of the code. Simply copying the ACPI tables verbatim may be legal (c.f. Sega case summary above about "purely functional" code), but parsing the in-memory tables and writing them out to disk (which is what's happening here, right?) is legal. (IMHO, IANAL, ...)
