[LinuxBIOS] Where to write up win / qemu / linuxbios / filo?
by David H. Barr 22 Nov '06

22 Nov '06

I've finished booting a full Ubuntu desktop in qemu via a LinuxBIOS/filo image. I accomplished this under MS Windows, using the virtual machine to build its own ROM. Any recommendations as to where this sort of build information would go? I started to write an article, but most of what was accomplished is already covered here: http://linuxbios.org/QEMU_Build_Tutorial It was a great (and totally free/riskfree) way to get my feet wet, and it felt like "the real thing" since, like many ports, I was using the target "board" as my development platform. At any rate, thanks for all the great docs and discussions. -dhbarr.

[LinuxBIOS] abuild and Config.lb

Back when I started it, the custom Config.lb in the target directory contained a lot of build specific stuff like payload ../../../../../../../somewhere/thisandthatpayload.elf which I assumed people needed to build and use LinuxBIOS in their environments. Also, these Config.lbs are all very different. Some are very verbose, some are completely silent. The idea was to create a config that is as simple as possible and the same for all boards. Since this is not possible, I started out using Config-abuild.lb on those boards that would not work with a "default configuration". What I do nowadays is replace the path to the payload while building the images (using /dev/null if no real payload is used). In the Config.lb file you just see payload PAYLOAD Ideally we could put Config-abuild.lb files in place for every mainboard. I could also make abuild automatically download payloads if no others are found in place, so it always builds with real payloads. When I started building all qa.linuxbios.org images with real payloads, half the boards broke, since they would not leave any room in the images for a payload at all. To work around a mess I started using compression in abuild every time a real payload is used. We should indeed make that an option to abuild.

[LinuxBIOS] Intel 440bx
by Shaddam Corrino IV 21 Nov '06

21 Nov '06

Hello folks, Ideally in few weeks I would like to use 440bx. It is my impression that it is not working right now quite right. Am I screwed? What I would need is LB+VGA bios (so that I can use working vesafb in linux). # lspci 00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 02) 00:01.0 PCI bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 02) 00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02) 00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 02) 00:0a.0 Multimedia audio controller: Ensoniq ES1370 [AudioPCI] (rev 01) 00:0c.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 20) 01:00.0 VGA compatible controller: S3 Inc.
