Does linux care the PCI IRQ tables created by LinuxBios? I thought it only look at the MP-table. gin

Assuming you just want to flash the bios with a given rom image, go to freebios2/util/flash_and_burn/ and do make there. The resulting flash_rom utility might help. For detailed information how to build LinuxBIOS itself for a given platform, see http://www.openbios.org/LinuxBIOS-AMD64.pdf The SIS6x0 is not yet supported by the LinuxBIOS v2 tree yet. Which means you cannot replace your motherboard bios with LinuxBIOS on those systems. > Openbios did not work for me, bios.ko had problems with my NIC. >From what I can see, flash_and_burn contains support for all chipsets and most if not all flashchips that /dev/bios supports, plus it is less intrusive, being a userspace program.

RFC: Generic shadow mechanism useable from a payload
by Richard Smith 31 Jan '05

31 Jan '05

Thinking about ADLO and the shadow enable/disable got some wheels turning. I've been spending lots of time in V2 and I was wondering if the same type of methodology can't work for ADLO. In V2 there are specifc .c files that do thing in a chipset specific way and the auto.c includes them as necesary. Those get compiled and then stuck in the startup assembly. What if we created a shadow.c file that was in the northbridge directory with a simple API type setup that enabled and disabled the various shadow ranges. Then the ADLO build system could just romcc these files and the loader would include them just like crt0.S does. That way there are no callbacks across the payload boundry yet you could setup ADLO or other payloads so they would work in a chipset agnostic way. I suppose that that FILO and the emulator render most of ADLO un-needed but if you are going to try and use FreeDOS or Windoze as an OS then you will need ADLO. -- Richard A. Smith

Where to start.....
by G.Marshall 31 Jan '05

31 Jan '05

Hello, At Stefan's suggestion, I have downloaded the latest V2 snapshot. I expected a Makefile, configure or README in the base directory which told me where to start and how to progress. I have found some details regarding a 2.4.0 kernel, but that appears to relate to V1. I have also looked at the LinuxBIOS.pdf by Anthony Stone. I just cannot work out where to start. Would someone be kind enough to point me to the start, and I can go from there. Intel Celleron SiS 650/M650 Host Bridge 2.6.10 kernel (from src not a pkg) Many thanks, PS Openbios did not work for me, bios.ko had problems with my NIC.

In other words it > uses a different cmos.layout file. My image only uses cmos for normal booting. For fallback booting it is hardcoded. Might be some issue with the reserved K8 areas in CMOS or the position of the checksums? Stefan

Hi, just to give some final feedback on this one. Using cmos_util worked fine whereas lxbios seemed to work "sometimes" but I did not track the exact issues down. Thanks for the hints. Stefan
