by Ronald G Minnich

This should whet your appetite for the 3-day linuxbios summit Oct. 11, 2005 in santa fe! For more information, http://lacsi.rice.edu/symposium/ Title: AMD's Roadmap for Free Firmware (as in Beer) Speaker: Rich Brunner, AMD Fellow Abstract: This will be a discussion of the upcoming AMD Processor roadmap, AMD plans for supporting LinuxBIOS, and AMD's directions for the future of firmware. Speaker BIO: Richard A. Brunner is the Software Architect for Advanced Micro Devices' AMD64 Architecture. He is an AMD fellow and is responsible for driving the technical direction of AMD's AMD64 software strategy for operating systems, device drivers, compilers, libraries, OS/firmware interaction, performance optimizations, and 3rd party tools. Richard led AMD's initial involvement into the Unified Extensible Firmware Interface (UEFI) forum.

[LinuxBIOS] romcc - Internal compiler error: Cannot find block dominated ....

by Doug Bell

0x8360d58 phi Internal compiler error: Cannot find block dominated by 0x82ba9a8 Any ideas on workarounds / fixes here? Is am I running out of registers or some other problem? __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

Re: [LinuxBIOS] VIA EPIA-MII in the supported list but no target?

But FILO doesn't setup any of the low level hardware. You need LinuxBIOS to initialise the cardbus bridge and then map the CF slot appropriately so that the IDE code in FILO can talk to your CF device. > what was the code that doesn't compile for? (I suspect once I hit send > all this will make sense but just now I seem to have lost it). It looks like it does initial configuration of the bridge and maps the CF card to 0x1E8->0x1F0. I don't have an EPIA-MII so I've only looked at it just now. J. -- There are always at least two ways to program the same thing.

[LinuxBIOS] testing again

by ron minnich

It has come to my attention that I've not been receiving mail from the list, hence this test. Something broke somewhere ... ron

[LinuxBIOS] VIA EPIA-MII in the supported list but no target?

by John Galloway

I'm looking at attempting to use LinuxBIOS to boot my VIA EPIA-MII10000 from the CF slot (a common desire among MII users, but with little success it seems). The EPIA-MII IS in the supported motherboards list, but targets/via only has an entry for epia and epia-m, no epia-mii. The M and the MII are different enough that I can't see them using the same target config. What gives? -jrg

FW: [Retrieved][LinuxBIOS] SATA issues with Tyan2891

by Edwin Morales

HI, Still having SATA issues with Linuxbios and the Tyan 2891. I am using Etherboot 5.2.6, network booting, with a PATA hdd as the RH drive and a SATA as a data disk mounting to /export. RH sees the SATA hdd but it cannot initialize. System comes up fine but no SATA. No special arguments passed for the NBI. Here is the output, I've also attached the LinuxBios output. SCSI subsystem initialized ata1: SATA max UDMA/133 cmd 0x3050 ctl 0x3092 bmdma 0x3030 irq 201 ata2: SATA max UDMA/133 cmd 0x3060 ctl 0x30A2 bmdma 0x3038 irq 201 ata1: no device found (phy stat 00000000) scsi0 : sata_nv ata2: no device found (phy stat 00000000) scsi1 : sata_nv ata3: SATA max UDMA/133 cmd 0x3070 ctl 0x30B2 bmdma 0x3040 irq 193 ata4: SATA max UDMA/133 cmd 0x3080 ctl 0x30C2 bmdma 0x3048 irq 193 ata3: PIO error, drv_stat 0x50 ata3: dev 0 not supported, ignoring scsi2 : sata_nv ata4: no device found (phy stat 00000000) scsi3 : sata_nv kjournald starting.

[LinuxBIOS] Executing Real-Mode Binaries

by San Mehat

Greetings, Are there any facilities for linking in and executing real mode binaries? I have a 'blob' that I need to execute fairly early in real mode. If not its fine, I can start on one... thanks ;) -san

[LinuxBIOS] sc520 support is in

by Ronald G Minnich

you can now build an sc520 bios for the digital logic msm586sev, and the ethernet works. Due to a glitch with hardware, the name of the target is mem586seg; I plan to fix this problem. For now, it's a great little cluster node. msm586sev is a nice little board, small, low power. To-dos - no vga bios yet (well, not totally, you can get it in user mode with the "testbios' program in linuxbios utilities, just not in linuxbios itself) - need to finish up dynamic memory sizing code - keyboard stuck error (no kb interrupts?) - reset is still not reliable this cpu was kind of a bear, and still does not fit well into the linuxbios way of doing things, and never will be that good a fit due to architectural design problems with the FLASH address map(see linux journal web article). I'm going to build a cluster of them anyway ... ron
