flash rom utility

[Gin]

Is there a flash rom utility I can use to flash linuxbios to my EEPROM?
Currently I am WICE to do it. But I can't depend on a hardware device to
update bios.

Check out the flash_rom utility included in the
freebios2/util/flash_and_burn directory.

Which flash part are you using?

Etherboot and Linuxbios

[Gin]

Etherboot version used: 5.3.11

I am trying to build a Etherboot image to work with Linuxbios but got a
compile error. There are couple undefined references to some functions
due to the settings in the Config file.

I commented out the PCBIOS option, and define the following.

-DLINUXBIOS -DCONFIG_TSC_CURRTICKS  -DCONSOLE_SERIAL -DCOMCONSOLE=0x3f8
-DCOMPRESERVE -DCONFIG_PCI_DIRECT -DELF_IMAGE

-DPXE_IMAGE -DPXE_EXPORT

p.s The undefined reference is due to the undefined PCBIOS.

Linux kernel in Rom

What Options should I enable if I want to embed a linux kernel with
Linuxbios in Version2?
CONFIG_FS_STREAM?

What should I use as the Linuxbios payload? What file format should it
be?

Linux kernel in Rom

[Ronald G. Minnich]

Here is my config file for a kernel version of linuxbios.
opteron_phase1_p4_noapic is a kernel that I ran mkelfImage on.

Let me know if this works, I just quick hacked it for the new config 
scheme but it is untested as of today.

target hdama
mainboard arima/hdama
option ROM_SIZE=0x100000
romimage "fallback" 
    option USE_FALLBACK_IMAGE=1
    option ROM_IMAGE_SIZE=0x10000
    option LINUXBIOS_EXTRA_VERSION=".0Fallback"
    payload ../../../../opteron_phase1_p4_noapic
end

buildrom ./luxbios.rom ROM_SIZE "fallback"

Ok. I will test on this config file.

I am trying to make my linux kernel image smaller as I want to embed it
with the ROM. Is there anyway you suggest to do this instead of using
the menuconfig in RedHat linux. I can only take out options provided in
the menu but the sometimes the dependency doesn't work that well. I get
compile errors later when make bzImage.
