Hi all,
At last... Finally I have had time to look at LinuxBIOS... I have been playing around with Etherboot and Filo for booting a development target, making good progress.
Up to now I have managed to add Etherboot to the original BIOS and have it working fine.
But now I want to LinuxBIOS my system ;-)
I have a Lippert Cool Roadrunner II with 64MB memory and a 128MB CompactFlash for disk, and I have tried to use LinuxBIOS v1 with its support for this board, but no success.
The serial port is very quite, and unfortunately I have no POST card. I have verified the serial connection: Linux on target "$ echo Hello
/dev/ttyS0" gives a nice "Hello" on the receiving end (no handshakes),
so something seems odd with the LinuxBIOS image...
Host is i686-Linux using gcc-4.0.3
--- config ------------ target /home/pdj/tuxway/builds/roadrunner2 mainboard lippert/roadrunner2
# Enable Serial Console for debugging option SERIAL_CONSOLE=1 option TTYS0_BAUD=57600
option DEFAULT_CONSOLE_LOGLEVEL=9 option DEBUG=1
option RAMTEST=1 option USE_GENERIC_ROM=1 option USE_ELF_BOOT=1 option ROM_SIZE=262144 option STD_FLASH=1
payload ~/tuxway/etherboot-5.0.6/src/bin32/eepro100.elf
option PAYLOAD_SIZE=196608 ---------------
I've hexdump'd the resulting romimage, and it looks fine as far as I can tell: (jmp far 0xf000:0x0004 at address 0x0003fff0, and payload image starting at 0x00000000).
I've used the flashrom from LinuxBIOSv2-2191 for burning: "# flashrom -w romimage"
Anyone able to give me a clue of what I've missed?
Anyone had success with LinuxBIOSv2 on a Roadrunner2 ?
~Per -----------------
PS: --- My ultimate goal is fast boot to either a remote image (through Etherboot) or a local linux on CompactFlash (filo and ext2).
My plan was to use LinuxBIOS with a combined filo and etherboot image as payload. Like this: 0x000000 FILO 0x010000 ETHERBOOT 0x030000 LINUXBIOS 0x040000 --- I have already modified filo so an external switch can select the boot-method.
