Just remind:

His MB has E7501 ....

So first step is make freebios2 work on that.

He may need to copy Tyan S2735 to make his MB copy at first. Then he .....

don't forget you can make your own!

I have

targets/arima/hdama/Config.filo.lb

and I do this:

./buildtarget arima/hdama/Config.filo.lb

File is this:

# Sample config file for the Arima HDAMA

target hdama.filo
mainboard arima/hdama

romimage "normal"
    option USE_FALLBACK_IMAGE=0
    option ROM_IMAGE_SIZE=0x10000
    option LINUXBIOS_EXTRA_VERSION=".0Normal"
    payload /opt/filo/normal/filo.elf
end

romimage "fallback" 
    option USE_FALLBACK_IMAGE=1
    option ROM_IMAGE_SIZE=0x10000
    option LINUXBIOS_EXTRA_VERSION=".0Fallback"
    payload /opt/filo/fallback/filo.elf
end

buildrom ./linuxbios.rom ROM_SIZE "normal" "fallback"

boot linux from an ide

[Gin]

Thanks everyone. I found the Config file for Tyan S2735.
1. why are the Config.lb files different under /target and /src for
Tyan/S2735? Which one should I use? Also the one under /target doesn't
specify the chipset model.

2. I was looking at the freebios instead freebios2. I notice it's a lot
different. How do I build the rom image from the freebios2 source? Is it
similar to freebios?

Thanks,
Gin

to build the S2735

cd targets
./buildtarget tyan/s2735

cd tyan/s2735/s2735

boot linux from an ide

[Gin]

I use FILO as the payload to boot from a Hard Disk, which has a
installed linux on it. I noticed if I enabled the ide stream. It tries
to read the ELF header from my IDE drive. But I thought the FILO payload
should be the one to load the image from the IDE drive. When does it
come in and play the role?
Anyone can explain the flow of booting if I try to load the INSTALLED
linux from a IDE drive.

If FILO is a payload in flash, then you need to set CONFIG_ROM_STREAM=1 
and CONFIG_ROM_STREAM_START to the address you want to start looking 
for the payload ELF header (usually just after the LinuxBIOS image). 
CONFIG_IDE_STREAM is used to load a payload (such as FILO) from an 
attached IDE device. This is useful if the flash is not large enough to 
hold LinuxBIOS+payload, but is probably not what you are looking for. 
Sorry for the confusion.

could not find a bounce buffer

[Gin]

Yes, I think I need to set CONFIG_ROM_STREAM=1 in order to have it boot
from my FILO payload which then will go load the image in a IDE drive.
Thanks.

I got an error when it ties to get_bounce_buffer in elfboot, Don't know
if you have the same problem. I dumped out the mem entries info. Looks
like the 2 mem entries are all LB_MEM_TABLE(ram config tables to be kept
in). So there is no LB_MEM_RAM, (where everyone could use) to allocate
the bounce buffer from.

Any idea?

=======================================================
Wrote the mp table end at: 00000020 - 000001f4
Wrote linuxbios table at: 00000500 - 00000be4  checksum 18e1

mem_entries=2
mem entry1: type=0x10, start=0, size=0xc4c
mem entry2: type=0x10, start=0xf0000, size=0x400

Could not find a bounce buffer...

You should use the Config.lb in the target directory. The Config.lb in 
the src/mainboard is a general config file to the mainboard. You can
make your own specific change in the target/ Config.lb.

Use freebios2 if it supports your mainboard. freebios is going to be 
obselete soon.

PXE support

Hello,
It seems like linuxbios supports PXE. Can anyone tell me how it works if
you have experience with it? Thanks

etherboot supports PXE. If you use etherboot as LB payload it should
work. Never tried this though since I can't really recognize an
advantage over the usual dhcp/tftpboot scenario. It's unlikely that you
are able to use any driver like code on the network adapters without
16bit bios.

I saw the Config options for PXE boot in Etherboot. Has anyone
successfully remote booted an image using PXE through Etherboot?

If so, what is the target name I should give to the makefile. I am not
sure how to build the file to use as the payload in Etherboot.
