Re: [Etherboot-developers] Bootrom hang at booting local - any ideas?

[Richard Shih-P. C. <csh...@ds...>]

Tried BOOT_INT18H but it didn't work either. It's got something
to do with the exit() function. I built a new ROM where
I commented out everything in main() so that it will fall through
to exit and it also freezes. Tried this on two different Gigabyte
mobos and had the same problem.

Any more ideas? BTW what is it that floppy does differently than
bootrom? Is there anyway to debug the return address (after main)?

Cheers
