All,
I got the mbuff working today. I truely don't know what I missed before I
got it working. But, anyway it works fine.
One question though -- I was using release 0.6.6 before, now the RTL2.3 is
packaged with version 0.6.3. I would prefer to keep myself at 0.6.3 since
it comes nicely with the kernel 2.2.14 rtl2.3 prepatched tar and I have to
deliver the system and write procedures for technicians (not at all computer
literate) to be able to re-build the system if something happens. Will I be
o.k. ? I only have 1 big array to hold A/D data that I read from a A/D
card.
Thanks in advance - Janet

Unfortunately, No, it gets loaded when I boot the miniRTL and I checked
to
make sure it is there.
