We have a 440gx based custom board. I have learned that it does not
have a RTC. Has anyone had any success with a board without a RTC, or is
it even possible? How much of a problem will this cause? =20
Should we get the board respun with a RTC? We would prefer using a 2.4
kernel, but would certainly go to a 2.6 kernel if that made things
easier.
Thanks in advance for any advice.

There shouldn't be any problems without RTC except the fact that you
need to worry about getting correct time.
I have many 4xx-based boards without RTC. They "just work".

No problems. Just set your time from another source. Many PPC boards
do this that don't need local time retention across power cycles.
I've got a 440gx board sitting here running happily this way.

Thanks to everyone who responded. Now that a RTC is not a requirement,
can anyone offer advice on what I will need to do to get the kernel
(2.4.18) to play nice?
Thanks,
Ed

Are you using the linuxppc-2.4 tree? If you want up to date 2.4 4xx
support you should be using that tree as a starting point. Support
is better yet in 2.6 where most developers are spending their time.
