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:
# Tyan s2881
option ROM_SIZE = 475136
option LINUXBIOS_EXTRA_VERSION="$(shell cat ../../VERSION)_Normal"
option LINUXBIOS_EXTRA_VERSION="$(shell cat ../../VERSION)_Fallback"
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
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
I have a feeling I'm missing something important. Any pointers?
