by Ravi 10 Dec '03

10 Dec '03

Hi, This is my first posting to this list. Before posting this mail I searched for any support of net 4501 soekris box. Is net 4501 soekris box is supported by linuxbios? Thanks in advance, Best Regards, Ravi

DOCM mapping address?
by Devi Priya 10 Dec '03

10 Dec '03

Hi, I like to have my linuxbios, linux OS, filesystem in the same diskonchip millennium. If I have to use diskonchip millennium with linuxbios, to which physical address should the DOCM should be mapped in hardware ? Is any driver should be loaded before the OS gets loaded? I have mapped in hardware 0xFFFFFFFF-0xFF800000. Is this correct? Does any remapping is to be done in hardware afer this? Which file system should I use? Regards, Priya. _________________________________________________________________ Discover India. Celebrate her diversity. http://server1.msn.co.in/features/tourism/ Come, fall in love!

legacy BIOS usage
by Ryan Underwood 08 Dec '03

08 Dec '03

Hi, I had the idea of using LinuxBIOS but also maintaining a legacy BIOS for debugging and dual boot scenarios. It would be linked into the LinuxBIOS image and jumped to alternatively depending on the user input. However, thinking about this gave me 2 questions: 1. Are there any forms of user input possible into LinuxBIOS loader? Is the system initialized enough to accept a keyboard input, or ACPI system button, or even something sillier like checking if a PS/2 mouse is plugged in (the user can unplug the mouse to signal LinuxBIOS to jump to the legacy BIOS instead). 2. Is it possible to get the machine into a state where it can check whatever form of user input is possible, but still be able to then put the machine back into a state where the legacy BIOS won't be confused. Or could something like this be done via the reboot vector instead? Power on clean gets you LinuxBIOS, but reboot goes to legacy BIOS... I guess the problem there again would be putting the hardware back into a state that the legacy BIOS can use. any ideas on that topic? It would be nice to use FreeDOS occasionally for testing some external hardware control programs, but FreeDOS requires a PC BIOS, of which there are no open source implementations that I know of. :( Maybe that can be a project for the future, but somehow I see a lack of interest in putting any new effort into a dead platform, so using the legacy proprietary BIOS might be the only real world choice. p.s. there is a broken Microsoft link in the FAQ, it is here now: http://www.microsoft.com/whdc/hwdev/archive/BUSBIOS/pciirq.mspx -- Ryan Underwood, <nemesis(a)icequake.net>

Eric, I mean in the amdk8_scan_chains, you need to put > config_busses &= 0x000fc88; > config_busses |= > (3 << 0) | /* rw enable, no device compare */ > (( nodeid & 7) << 4) | > (( link & 3 ) << 8) | > ((dev->link[link].secondary) << 16) | > ((dev->link[link].subordinate) << 24); > f1_write_config32(config_reg, config_busses); before /* Now we can scan all of the subordinate busses i.e. the > chain on the hypertranport link */ > max = hypertransport_scan_chain(&dev->link[link], max); YH.

Eric, Please check the northbridge.c attached. It seems you should modify the e0 before you do the hypertransport_scan_chain. Otherwise you can not access the buses. YH. config_busses &= 0x000fc88; config_busses |= (3 << 0) | /* rw enable, no device compare */ (( nodeid & 7) << 4) | (( link & 3 ) << 8) | ((dev->link[link].secondary) << 16) | ((dev->link[link].subordinate) << 24); f1_write_config32(config_reg, config_busses); #if 1 printk_debug("Hyper transport scan link: %d max: %d\n", link, max); #endif /* Now we can scan all of the subordinate busses i.e. the chain on the hypertranport link */ max = hypertransport_scan_chain(&dev->link[link], max);

If only - Fix amdk8_scan_root_bus and amdk8_scan_chains so multiple HT chains can be scanned in any order it will not break the code. There must some other file changes cause that.

The problem was that builds that worked friday stopped working this morning, due apparently to this: Revision 1.9 - (download), view (text) (markup) (annotate) - [select for diffs] Sat Dec 6 00:11:56 2003 UTC (2 days, 19 hours ago) by ebiederm CVS Tags: HEAD Changes since 1.8: +21 -8 lines Diff to previous 1.8 - Fix amdk8_scan_root_bus and amdk8_scan_chains so multiple HT chains can be scanned in any order === it was your push, not mine. It broke all the K8 builds. I would normally not have pushed your stuff out but this was kind of an emergency. Trust me, I'm not going to push your changes out before we test 'em, but I can't stop you from doing it :-) thanks ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

your builds are broken today due to the missing amdk8.h file in src/northbridge/amd/amdk8. Do an update; I just added it. ron
