Re: [Trinux-talk] Compiling a Trinux-compatible kernel

[J. R. v. B. <jr...@cs...>]

Hey Matthew - 

The kernel's bundled w/ Trinux work like a charm - I can boot to them
via loadlin from a DOS partition, through lilo, or from a floppy.  The
default redhat kernels (which all include initrd and ramdisk support),
as well as the ones I've built all fail, even with all other
configurations being identical.  I've seen this behavior now on two
different machines, one a dual processor Pentium 6, and the other a
single processor Celeron.  I just tried passing mem=XXX to the kernel,
but that didn't help.  ;-(

Are there any other things that need to be done?  (eg, using rdev to set
some magic options in the kernel image, etc.)  Would it be possible for
me to see a copy of the kernel .config you are using these days?  I'd
like to at least rule out kernel options as a variable.  

Thanks for your help!!

Best,

-Rob
