Applied. Some of the patches though didn't put there resulting
files in the correct places. For example ram.ld ended up at the
top of the linux-2.4.x directory, instead of down under
linux-2.4.x/arch/m68knommu/platform/5282/SERRA.
Yes, there was another little bug I notice now.... Here you have fixed
if you didn't fix it.
The patch #8 is partial in binary mode because I added some images to
the webserver
I have only one question, on the patch #10 I have to modified the
telnetd Makefile form the user application to be able to start/stop
telnetd service. Now the inetd.conf is on flash, and we can modify. Is
this the correct way to start/stop telnetd?
I would do this in your vendor specific Makefile.
I'll try it

Greg
