Hello,
I am trying to run the "coreinfo" payload on Qemu using the prebuilt image from the link:
http://www.coreboot.org/images/0/06/Qemu_coreboot_coreinfo.zipHowever, the ZIP file seems to be corrupted, I cannot extract the file. Could you update the link with the uncorrupted ZIP file?
looks like the file gets unzipped somewhere on the road without rena- ming. If yours is 262144 Bytes in length too, you can simply treat it as `coreboot.rom`.
Although, it shouldn't be hard to build your own, see: https://www.coreboot.org/Lesson1

Hi Nico,
Thanks for your reply. I had initially followed Lesson 1. Although I was able to build the Coreboot and Coreinfo successfully, when I ran the package (coreboot + coreinfo) on Qemu, the screen that appeared had only a green, narrow band which read "coreinfo 0.1". That is, I did not get any interaction with the Coreinfo program by pressing any keys.
Also, after around a minute, Qemu is crashing with the following messages:
e1000: Writing to register at offset: 0x00002410. It is not fully implemented. e1000: Writing to register at offset: 0x00002418. It is not fully implemented. e1000: Writing to register at offset: 0x00002420. It is not fully implemented. e1000: Writing to register at offset: 0x00002428.

It is not fully implemented. qemu-system-x86_64: Trying to execute code outside RAM or ROM at 0x00000000000a0000 This usually means one of the following happened:
(1) You told QEMU to execute a kernel for the wrong machine type, and it crashed on startup (eg trying to run a raspberry pi kernel on a versatilepb QEMU machine) (2) You didn't give QEMU a kernel or BIOS filename at all, and QEMU executed a ROM full of no-op instructions until it fell off the end (3) Your guest kernel has a bug and crashed by jumping off into nowhere
This is almost always one of the first two, so check your command line and that you are using the right type of kernel for this machine. If you think option (3) is likely then you can try debugging your guest with the -d debug options; in particular -d guest_errors will cause the log to include a dump of the guest register state at this point.
Execution cannot continue; stopping here.
Do you observe the same problem when you follow the instructions in Lesson 1 and build Coreboot and Coreinfo from the sources? I am attaching the screenshot of Coreinfo.
