Re: [LinuxBIOS] [FEATURE] payload compression

[Lu, Yinghai]

The Etherboot 5.4 later has different size in elf prefix... to real file
size.

So we need to align rom_end to 16 bytes or use dd to make payload to 16
bytes align before nrv2b payload.nrv2b...

Which one is good?

Makes perfect sense!

So Etherboot produces corrupt ELF files per default? Can we fix this in
Etherboot?

Hm - whatever produces the smaller or cleaner patch..

Hello,

We will be happy to fix this.  Can you be more specific about what is  
wrong with the elf prefix that Etherboot is creating?  Better yet, if  
you could download an Etherboot-5.4.2 tarball from:

http://prdownloads.sourceforge.net/etherboot/ 
etherboot-5.4.2.tar.gz?download

and look at:

etherboot-5.4.2/src/arch/i386/prefix/elfprefix/elfprefix.S

it might shed some light on the problem.

Thanks,

Marty
