How big is your flash chip? How big is the image you are 
burning?

Do you have a serial cable attached to the machine and 
the correct baud rate set?

Before I get BIOS download from IWILL's website. 
The .ROM file is 524288 bytes. Is this the flash_chip
size? The linuxbios.rom built is 1048576 bytes.

I didn't connect the serial cable to the machine. And
do you mean set the baute rate in Bios settings?

Thanks.

Then you probably flashed half of LinuxBIOS only.. You need to create
one that is 512k big if that is the size of your flash chip

Connect the board with a serial cable to another machine. you will see
lots of output if LinuxBIOS is there. (i think 115200 baud is the
default)
VGA is still a bit tricky in LinuxBIOS

Hi, Stephan, Thanks for the information.
By changing the ROM_SIZE in the Config.lb, I get 
a linuxbios.ROM of 524288 bytes and flashed it to the
destination node.

After that I connected the null modem cable to another
machine, use minicom and configured the serial poart 
as 115200 8N1, quite and restart the minicom again and
then started the machine with linuxbios flashed. But I
cannot see any inputs. What could be the problem?

Thanks.

[LinuxBIOS] A question about compiling linuxBIOS

[Frank Samuel]

hi, all,
I got some new progress by more experiments.

It seems that my serial connection was working. When I
reboot the machine by running "reboot", I saw a string
of LinuxBIOS $Version Starting...
My board is Iwill DK8S2. This seems to be what main()
of auto.c prints when it call console_init().
report_bist_failure is also alled. 
But setup_default_resource_map failed. Don't know why
this failed.

If I power down the target machine, I can see nothing.
I checked the cmos.layout. I saved cmos settings to a
file by cmos_to_file and read it via
cmos_util, I get a settings file in which baud rate is
1200. This desn't match with the cmos settings of the
machine. I am wondering whether cmos.layout is
still correct now since iwill motherboard changes 
structure of cmos settings pretty frequent. Could this
be the reason that I cannot see any output of
linuxbios after the target machine power up? BTW, how
cmos.layout for Iwill is created? by flipping cmos
settings and observing the differnces of the binary
file or Iwill provides this?

Can someone provide some hints? Thanks a lot.
