Subject: Re: Getting the image section of the ELF file to load w/ VxWorks boot

Message-ID: <m12pEA0-001SyZC@bucks> (raw)
In-Reply-To: <391834D3.9E57B710@Zentropix.com> from "Daniel G. Clemmensen" at May 09, 2000 11:54:59 AM
The approach that I settled upon was identified in my initial post,
however I didn't actually do all the steps. I have attached the the
files that are needed to make it work.
Note: The Linux_2_3 BitKeeper repository at FMS Labs contains
these changes.
