What SVN rev are you using? I thought Stefan reciently fixed up all the compile and alignment issues to work with newer compilers. Its ok if flashrom and the linuxbios image are compiled with different compilers. -- Richard A. Smith

[LinuxBIOS] EPoX 8KTA3 Mainboard
by Keven L. Ates 13 Dec '05

13 Dec '05

Hello All, Can anyone give me some feedback on using LinuxBIOS on the following: EPoX 8KTA3 Mainboard AMD Athlon 1GHz Socket A "lspci" output follows AGP Video Card - ATI Radeon PLCC with Award BIOS v6.0 (flashed updates with awdflash.exe) Some MBs may also have an optional RAID chip. http://www.epox.com/USA/product.asp?ID=EP-8KTA3 As it uses VIA chip I'm hoping for the best. I'm currently using SuSE Linux 9.3 (2.6 Kernel) and Windows 2000 booting from GRUB on the MBR of boot partition and would like LinuxBIOS to call the MBR (so LinuxBIOS only needs to do the minimum). NOTE: It seems to me that much of the configuration of a system can be derived from a linux installation directly such that the LinuxBIOS make can "read" a system its compiling on and set itself up. Particularly, it could "lspci", read the active BIOS or a supplied BIOS file for the video, etc. with very little user intervention and create an appropriate LinuxBIOS for the machine. Yeah, I know, what if you need to compile on one machine and feed to another? But, how about a "what if you don't" option? Could it be made to do it automagically? linux:~ # lspci -vvv 0000:00:00.0 Host bridge: VIA Technologies, Inc.

[LinuxBIOS] tyan s2881
by Ward Vandewege 12 Dec '05

12 Dec '05

Hi there, First of all, thanks for upgrading the SVN tree, it now compiles without problems (but still lots of warnings ;) for the Tyan s2881. I've managed to build a Linuxbios image, using FILO 0.5 and the latest subversion revision of the Linuxbios tree (2141). So I've compiled filo, built the rom image, and burned the rom into our biossavior. This is the filo configuration file I used: USE_GRUB = 1 MENULST_FILE = "sda1:/grub/menu.lst" AUTOBOOT_FILE = "sda1:/vmlinuz-2.6.12-9-amd64-generic root=/dev/sda4 console=tty0 console=ttyS0,19200n8" AUTOBOOT_DELAY = 4 IDE_DISK = 1 VGA_CONSOLE = 1 PC_KEYBOARD = 1 SERIAL_CONSOLE = 1 SERIAL_IOBASE = 0x3f8 SERIAL_SPEED = 19200 FSYS_EXT2FS = 1 FSYS_FAT = 1 FSYS_REISERFS = 1 FSYS_ISO9660 = 1 ELTORITO = 1 SUPPORT_PCI = 1 PCI_BRUTE_SCAN = 1 LINUX_LOADER = 1 PCI_CONFIG_1 = 1 I'm unsure about the references to sda in the MENULST_FILE and AUTOBOOT_FILE parameters. This is how my running kernel sees the SATA drives; Linuxbios supports booting from SATA, right? The Config.lb I'm using is: target s2881 mainboard tyan/s2881 # Tyan s2881 romimage "normal" option ROM_SIZE = 475136 option USE_FALLBACK_IMAGE=0 option ROM_IMAGE_SIZE=0x20000 option XIP_ROM_SIZE=0x20000 option LINUXBIOS_EXTRA_VERSION="$(shell cat ../../VERSION)_Normal" payload ../../../../../payloads/filo.elf end romimage "fallback" option USE_FALLBACK_IMAGE=1 option ROM_IMAGE_SIZE=0x20000 option XIP_ROM_SIZE=0x20000 option LINUXBIOS_EXTRA_VERSION="$(shell cat ../../VERSION)_Fallback" payload ../../../../../payloads/filo.elf end That's pretty much the stock version from the SVN tree. I used the flashrom tool to burn & verify the image. That works perfectly. Unfortunately, when trying to boot it, nothing happens. Nothing on the screen (but I didn't expect that as I'm still not clear about the whole vga bios thing). I've hooked up another linux box for capturing the serial output, and verified that that setup works (serial login to s2881 works, running the proprietary bios). When booting linuxbios, there is no output on the serial line. This MB has POST leds onboard; when booting from poweroff, they remain stuck at FF when using the linuxbios image. When booting the proprietary image, they cycle through a whole range of numbers, to finish on 00 once the system is up. I have a feeling I'm missing something important. Any pointers?

Biederman; LinuxBIOS Subject: [LinuxBIOS] Fwd: [issue50] put pgtbl after 1M Eric, I moved the pgtbl to the last 1M of CONFIG_LB_MEM_TOPK.... Please check it.

The reason is every cpu page table will be 20k, and if there is 16 cpu will need 320k, it will push the stack and heap cross the 0xa0000, the region for vga font buffer. TO use that need to set CONFIG_LB_MEM_TOPK in MB Options.lb It also remove the hardcode 1M in clear_1m_ram.c to use CONFIG_LB_MEM_TOPK.
