x86emu / bios-emu gnuarch repository
by Stefan Reinauer 29 Sep '04

29 Sep '04

Hi, I finally set up a GNU arch repository for x86emu+intXXemu development. With this tree we should try to unify the x86 and legacy bios interrupt emulation that the various projects out there need. If you want to reach it, you have to use tla (http://www.gnuarch.org/) or a the snapshot facility at http://www.openbios.org/arch/ To check out the work from the repository directly, you have to do: tla my-id 'Your Name <name(a)example.org>' tla register-archive ftp://ftp.openbios.org/pub/arch/x86emu@openbios.org--devel/ tla get x86emu(a)openbios.org--devel/bios-emu--devel--2004 bios-emu More information (trimmed towards OpenBIOS though) can be found in Patrick Mauritz' very nice tla primer: http://www.openbios.org/~oxygene/tla-primer.txt NOTE: The tree has no patches from LinuxBIOS' testbios or any other project using x86emu included. It is purely taken from X.org X11R6.8.1 It won't even build. Though, I decided to use the X.org code since it is the most sophisticated version out there with most testing. Patches, comments, ideas are very welcome. If you think you need write access to this archive, let me know. Regards, Stefan

I seem remember few people mentioning to me that they could not find the SEBOS/ADLO/WinInt web pages. I'm told they have been restored at : http://www.missl.cs.umd.edu/sebos.html enjoy.

PCI IRQ tables
by Dave Aubin 29 Sep '04

29 Sep '04

Hi, What happens if the pci irq mapping is a mess? I know you can use getpir with a good bios, but what if you don't have one? Is there a way to get the pci irq mapping without a standard bios? If you had to do it by hand could you explain how it should be done? Thanks, Dave

awdbedit's Chipset Registers
by Bryan E. Chafy 28 Sep '04

28 Sep '04

OK, I downloaded linuxbios but I dont have a supported board/chipset (an older acer aspire with an ALI chipset). And of course, acerlabs makes it a policy not to give away their specs. But there still might be hope. Award bios's exist for other boards with the same chipset (take a look at http://www.wimsbios.com/index.htm?/numbers.shtml for a cross reference). I got one of those bios files and loaded it in awdbedit. awdbedit lists the chipset registers, or so it seems (click Recognized Items->System BIOS->"Chipset Registers" tab, as well as the "Setup Menu" tab.) Could that be enough info to get a board up and running? The tables look kinda raw, ie no distinction between northbridge/southbdride etc. The "Setup Menu" tab gives a little more detialed description for some registers. Are there any chipset experts out there who could comment on this?

RE: nVidia CK804 support

We will get answer this week. -----Original Message----- From: Craig C Forney [mailto:cforney@opus.com] Sent: Tuesday, September 28, 2004 12:01 AM To: linuxbios(a)clustermatic.org Subject: nVidia CK804 support We are in development of a dense dual Opteron board with nVidia's CK804. I understand that YH has been able to port LinuxBIOS for the TYAN S2895 which has a pair of CK804's. I'd really like to make LinuxBIOS available on our board, which is designed to be a blade in a cluster. What is the status of this code, and what are the possibilities/problems related to it's availability? I'd be happy to test/verify the code it in our configuration (which is somewhat different than the TYAN 2895). Any information/assistance appreciated.

(1)I disabled i786/earlymtrr, RAM NOP ok (2)After executing original bios, RAM NOP couldn't pass. Maybe I should set mtrr correctly. zhu _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com

Kernel for linuxbios
by Sagiv Yefet 26 Sep '04

26 Sep '04

I am using linuxbios with etherboot. In tyan2850. The only kernel so far that was loaded by the bootloader and run is: Cwlinux. www.cwlinux.com/downloads I tried without success: 1. Thinstation (etherboot) 2. Kernel from kernel.org. Is there any specific version I need to use of those kernels? Are there any patches made for the kernels that I didn't use? Where can I find them. What could be the problem? Sagiv
