Hi,
after putting some debug statements, it seems the LinuxBIOS resets after the jmp instruction is boot.c ( " jmp *%%eax\n\t" in jmp_to_elf_entry) fails. I am using ETHERBOOT payload with IDE support. Is it because the ram initialization is not proper or something, has anyone experienced this kind of problem.
Any pointers, why it should fail over here.
Here is the extract of the log ...

that problem is typically RAM initialization. I think you are going to need to run memtest86 and look for problems.
But congratulations, you are making progress.

Could you please elaborate on how to use memtest. Can we use it with etherboot, what is the procedure?

use memtest INSTEAD of etherboot as the payload. I have a memtest elfimage lying around here somewhere if you need it.

I have tried it and it doesnot work. linuxbios resets at the jmp instruction, where it is supposed to jump from rom to ram. So how is memtest payload supposed to work, if there's a problem with ram initialization. Any other suggestions on how to use memtest.

are you setting CONFIG_COMPRESS=0 in your config? If not, do so. You don't want to use ram at all if ram is not working.

I'm haveing a little difficulity with the nsuperio setup.
I keep getting a undefined reference to superio_NSC_pc87351_control
I see that nlbconfig generates a prototype reference
extern struct superio_control superio_NSC_pc87351_control;
in nsuperio.c but I don't see where the the actual struct definition is/should be.

I found it.. I missed updating that from the WinBond example I started with in my NSC/pc87351/superio.c file.
tried even setting CONFIG_COMPRESS=0 , but no luck....

I would say a RAM problem. Have you run remtest.inc?

I had the same thing after updating from etherbot 5.1.7 to 5.1.8 when I forgot to change the config file to build for LinuxBIOS instead of PC bios. I assume etherboot tries to call some intXX services early in that case which might cause the reboot. Did not investigate further after it worked though
